1 22. The Resource Games 04/24/2017 EQ: Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem. This will be answered by the end of the lesson!

2 22. The Resource Games 04/24/2017 EQOD 1: Explain two different types of competition that exists between populations within an ecosystem Initial Thoughts: If you had to compete in something, what would it be and why?

3 Evidence I: My.BEANS!! Let s Play a Game :) We ll get in groups of 4 around the table. Goal: To get as many beans in the cup as possible within 15 seconds Assign from oldest to youngest A, B, C or D. Each will represent traits for survival. Some will give more of an advantage than others.

4 Evidence I: My.BEANS!! Goal: To get as many beans in the cup as possible within 15 seconds Flip your card! A. You are only allowed to use your pencil between your teeth to capture beans. B. You are only allowed to use your elbows to capture beans C. You are only allowed to use your pencil held in your fingers to capture beans D. You are only allowed to use a finger from each hand to capture beans. Who do you think will be able to get the most beans? Who will get the least?

5 Evidence I: My.BEANS!! Goal: To get as many beans in the cup as possible within 15 seconds # of Beans Adaptation A. Pencil and Teeth B. Elbows C. Pencil and Fingers D. Just 2 Fingers

6 Evidence I: My.BEANS!! Each of you had a different trait that worked differently as your competed for beans. This is how animals compete for resources in their ecosystem. Traits are certain characteristics of an organism. Traits help animals with competition. Competition is a negative interaction that occurs among organisms whenever two or more organisms require the same limited resource

7 Evidence I: My.BEANS!! How can we see competition with humans? What do polar bears in the Tundra compete for? What do trees in forests compete for?

8 Evidence I: My.BEANS!! There are different ways organisms can compete in their ecosystem. Overproduction: The production of a lot of the same organism by a population. AKA: Having a lot of babies! Why do you think rodents like rats and bunnies have tons of babies?

9 Evidence I: My.BEANS!! There are different ways organisms can compete in their ecosystem. Variation: Differences between populations of the same types of species that help with survival. Example: Huskies vs. Golden Retrievers How are both of these dogs different? How do their differences help them survive?

10 Evidence I: My.BEANS!! There are different ways organisms can compete in their ecosystem. Selection: Traits that allow certain organisms to survive in their ecosystem. Example: Darwin s Finches! If both types of Finches existed in an island with only bugs inside tree trunks, who would survive? Who would lose the competition of life? What if they were required to break acorns?

11 Evidence I: My.BEANS!! There are different ways organisms can compete in their ecosystem. Adaptation: The ability for an organism to change a certain part of themselves to survive in their ecosystem. Example: Venus Fly Trap Since the soil in their ecosystem doesn t have a lot of nitrogen, how have Venus Fly Traps adapted to get nitrogen from a different source?

12 Evidence I: Exit Ticket Question: Explain two different ways organisms compete in an ecosystem. 1. Adaptation 2. Selection 3. Overproduction 4. Variation Extra Credit: Explain how rabbits relate to the words you used. For example, How do rabbits adapt? Why do rabbits overproduce? Provide Evidence from your recent notes! Don t just put page number and lesson title.

13 Evidence II: I Like Turtles :3 EQOD: How does competition affect Sea Turtles?

14 Evidence II: I Like Turtles :3 Match the term with its scenario! 1. Because the Journey of a newborn sea turtle is full of dangers, sea turtles lay tons of eggs to make sure some survive. 2. Sea turtles have large shells that protects them from danger 3. Sea turtles usually swim fast in the ocean, however they may also crawl on land 4. There are 7 types of sea turtles! Variation, Overproduction, Adaptation, Selection

15 Evidence II: I Like Turtles :3 Match the term with its scenario! 1. Because the Journey of a newborn sea turtle is full of dangers, sea turtles lay tons of eggs to make sure some survive. OVERPRODUCTION 2. Sea turtles have large shells that protects them from danger SELECTION 3. Sea turtles usually swim fast on the ocean, however they may also crawl on land ADAPTATION 4. There are 7 types of sea turtles! VARIATION How does each help them survive?

16 Evidence II: I Like Turtles :3 Loggerhead Sea Turtles Facts 1. They are mainly carnivores and eat animals like jellyfish, conchs, crabs and fish 2. They swim by following the currents 3. They travel back to the beach where they hatched to lay their eggs.

17 Evidence II: I Like Turtles :3 Loggerhead Sea Turtles Facts 1. They are mainly carnivores and eat animals like jellyfish, conchs, crabs and fish 2. They swim by following the currents 3. They travel back to the beach where they hatched to lay their eggs. Scenario 1: In 2015, there was a sudden drop in the number of jellyfish and crabs in the U.S. Coasts. How did that affect the Sea Turtle population?

18 Evidence II: I Like Turtles :3 Loggerhead Sea Turtles Facts 1. They are mainly carnivores and eat animals like jellyfish, conchs, crabs and fish 2. They swim by following the currents 3. They travel back to the beach where they hatched to lay their eggs. Scenario 2: In 2007, the California Current was affected due to Global Warming. How did that affect the Sea Turtle's ability to get to shore?

19 Evidence II: I Like Turtles :3 Loggerhead Sea Turtles Facts 1. They are mainly carnivores and eat animals like jellyfish, conchs, crabs and fish 2. They swim by following the currents 3. They travel back to the beach where they hatched to lay their eggs. Scenario 3: In 2013, a popular beach where Sea Turtles lay their eggs was about to be closed down to make a 5-Star Hotel. How did this affect the Sea Turtles?

20 Evidence II: I Like Turtles :3 EQOD: How does competition affect Sea Turtles? Think: 1. Adaptation 2. Selection 3. Variation 4. Overproduction Sea Turtles use for competition because it helps them by In Evidence II of Lesson 22, it says that

21 Evidence III: A Community Story... EQOD: How does resource availability affect populations in an ecosystem? Answer this question in your journal: If you had endless food, money and water, what would you do with it?

22 Evidence III: A Community Story... We are going to build a story about a Community! You ll get to pick the animals and guess what happens to the population. We ll share with our partners and I ll pick a volunteer to share their story :) Ex. There was once a population of (primary consumer) zebra. They lived super happy in the (ecosystem) grassland.

23 Evidence III: A Community Story... There was once a population of (primary consumer). They lived super happy in their (ecosystem). They all had tons of water and food to eat so their population (grew or shrunk?) a lot. However, one horrible day, there came a (secondary consumer/predator). This predator was hungry too and needed to eat. The predator saw (same primary consumer) and decided that it was dinner time! The predator s population began to grow and because they, too, needed food, the population of (same primary consumerl) began to (grow or shrink?). However, because the population of (same primary consumer) became (smaller or bigger), that meant less food for the predator and soon their population began to (grow or shrink?) too.

24 Evidence III: A Community Story... Resources availability affects population. The number of resources available for an organism will cause the population to grow or shrink More resources = population growth Less resources = population shrinks What would happen to us in San Diego if all of a sudden all the water in Southern California dried up?

25 Evidence III: A Community Story... Resources availability affects population. The number of resources available for an organism will cause the population to grow or shrink More resources = population growth Less resources = population shrinks What would happen to us in San Diego if all of a sudden all the water in Southern California dried up? We would either pass away :( or it could create

26 Evidence III: A Community Story... Resources availability affects population. The number of resources available for an organism will cause the population to grow or shrink More resources = population growth Less resources = population shrinks What would happen to us in San Diego if all of a sudden all the water in Southern California dried up? Our population would go down :( or it could create competition! Less resources for everyone in a Community = More Competition

27 Evidence III: A Community Story... Let s analyze this graph between moose and wolves! Work on your own to answer the questions from your worksheet to your journal. We ll then compare with a partner.

28 Evidence III: A Community Story... What is the graph showing you?

29 Evidence III: A Community Story... What is the graph showing you? Moose act as prey to the Wolves. A larger moose population meant a larger Wolf population. Eventually, with more wolves eating the moose, then their population would go down as less moose would become available.

30 Evidence III: Exit Ticket EQOD: How does resource availability affect populations in an ecosystem? Resource availability affects populations because. According to the graph from Evidence III of Lesson 22, the data showed

31 Analysis 1. Sunflowers are known for their fun shape and form. As they grow, young sunflowers turn their stems to allow their flower to follow the sun. Also, they produce a lot of seeds. Label each trait to its type of competition. (Example: When sunflowers turn their stems to follow the sun, that is a form of ) 2. Flowers compete using their bright colors to attract pollinators like bees to help them reproduce. Unfortunately, global warming are causing bee populations to die quickly. Predict what will happen to our flora if our bee population keeps decreasing. Flora = Plants

32 Analysis 3. Orange Trees require water to grow. The annual rainfall between in San Juan changed a lot between How did the annual rainfall between affect the number of Orange Trees during those years?

33 Reflection Create a 3-5 Panel Comic Strip that shows competition between plants or animals in a community. It must include a competition for resources and one of the following: Adaptation Overproduction Variation Selection

34 Summary, Big Idea and Vocab Take 7 minutes to work in a level 0 silence voice on your summary. EQOD: Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem. Big Idea: Growth of populations makes it harder for organisms to get resources. Animals and plants compete for different type of resources like water, food, oxygen and more. New Vocabulary Terms: Overproduction, Variation, Selection, Adapation, Trait, Competiton
