Ecosystems are really fun to learn about, and I am going to tell you about them right now. An ecosystem is a living system. That means that lots of living things live in an ecosystem like deer, bears, raccoons, and lots of other animals. Some ecosystems are oceans, forests, wetlands, and swamps. Any place where animals and plants live is an ecosystem. If you have been to the beach you have at least been to one ecosystem. The ocean has so many living things like fish and coral. We should also protect these areas. If we don’t terrible things will happen. If trees burn down in a jungle or a forest we won’t have fresh air to breath. Trees help make the air fresh and strong. When we don’t take care of ecosystems lots of animals will die. Animals depend on each other. We also need to be careful of setting fires. A forest fire can ruin a whole entire ecosystem. Ecosystems are very important to us and our world.
