In the natural world everything is connected. Ecosystem is a community of non - living and living things  that work together. Ecosystems have no particular size. An ecosystem can be as large as a desert or lake or small as a tree or puddle. A healthy ecosystem has different species  diversity and is less likely to be seriously damaged by human interaction, natural disasters and climate changes. Species have a niche in its ecosystem that are helping keep the system healthy. We are learning about species every day, and we are just figuring out the roles they play in the natural world. An ecosystem has lots of different living organism that interact with each other. The living organism in an ecosystem can be divide into three categories: Producers, Consumers,  and Decomposers. Producers are the green plants. Consumers are animals and they get their energy from the producers or from organism that eat producers. There are three types of consumers: herbivores are animals that eat plants, carnivores are animals that eat herbivores and sometimes other carnivores and omnivores are animals that eat plants and other animals. The third type of living organism in an ecosystem are the decomposers. Decomposers are plants and animals that break down dead plants and animals into organic materials that go back into the soil. What are the major parts of an ecosystem? An ecosystem includes soil, atmosphere, heat and light from the sun, water and living organisms. Soil is a critical part of an ecosystem. The atmosphere provides oxygen and carbon dioxide for the plants and animals in an ecosystem.
