Zoology

In our class we learned about the animals, for example bacteria is the first organism that have life on Earth. We learned about different kinds of organisms that live in the world, for example in ocean there are different kinds of living things like star fishes and turtles. After that we learned about invertebrates and vertebrates. Invertebrates are the organisms that don’t have a backbone. Vertebrates are the organisms that have backbone. Ex: cow have a backbone, sponge don’t have a backbone. We learned about marine animals and territory animals. Marine are the organisms that live in the ocean only. Ex: Octopus are a marine animal. Territory are the organisms that live on land. Ex: cats are the territory animals. In the water there are a lot of insects. We learned how the insects metamorphosis. Metamorphosis means change. We learned about the metamorphosis are about their life cycle. In class we learned a lot of things most things that we learned are about the mammals. Mammals are the organisms that have a baby in their belly and give their baby a milk like a human.
