Explain how endangered animals can be protected. : Discovering Futurebuilders Pub. Inc., 2012 : Bonifacio V. Navarette Jr., Malyn B. Enojado Pages : pp ; : Endangered animals are those whose population are in danger of becoming extinct. Extinct means that particular animal species no longer exist. Some of our endangered animals are tamaraw, sea cow or dugong, tarsier, Philippine Eagle, Philippine Crocodile, Philippine Duck, green sea turtles and others. Pollution, Habitat loss, illegal hunting of wildlife and other non-environmentally friendly practices cause animals to become endanger. There are different ways to help save endangered species. Protecting and conserving our wildlife is everyone s duty.

16 Activity Sheet # 16 : World of Animals Learning Objectives : Answer each item in the quiz correctly. Follow directions in the test accurately. Observe honesty at all times. Pages : pp : Animals are divided into two big groups: vertebrates and invertebrates. Invertebrates are animals without backbone. They have eight Phyla arranged from the simplest to the most complex: porifera, cnidarians, worms, mollusca, echinoderm and arthropoda. Vertebrates are complex in their body parts and functions. Vertebrates are chordates because they are animals with backbone. They can be classified as bony and cartilaginous fishes, amphibian, reptilian, aves and mammalia. Humans are stewards of God s creations. We should take care and love animals not abuse them. Animals have structural and behavioral adaptation to get food and for self-preservation.
