7 Omnivores are animals that eat both plants and animals.
8 Look at these pictures. Can you decide what type of food each animal eats?
9 Classification of Animals Vertebrates-An animal that has a backboneEx: fishInvertebrate-An animal without a backbone. 95% of animals are invertebrates.Ex: worm
10 Bilateral symmetry- an object has a line that divides the object into halves that are mirror images.
11 Radial symmetry- many line(s) of symmetry that all go through a central point.
12 Animals with radial symmetry Live in the waterDo not move very fastDo not have distinct front or back endsStay in one spot or move with currentsAre able to sense their environment in all directions.
13 Animals with bilateral symmetry Larger and more complexHas a front end that goes first as the animal movesMove quickly and efficientlyHave sense organs in their front end(All vertebrates have bilateral symmetry)
14 Bilateral symmetry can be an advantage to a predator because: These animals are larger and more complex.They are streamlined and balanced.They have a front end that moves first making them faster and more efficient.They have sense organs on their front end to pick up information.
33 Formation of coral reefs Over time as the coral polyps die, their skeletons remain behind. Rocklike masses called reefs form after thousands of years. The Great Barrier Reef near Australia is about 2,000 kilometers long.
34 Importance of coral reefs Home to more species of fishes and invertebrates than any other environment on Earth.
