There is a large diversity in an ecosystem, for example, the species, environment, and the plant diversity in the ecosystem. It’s difficult to model ecosystems because the model needs to be accurate and as well as precise.

In an ecosystem, organisms have many ways to get energy. One way is a producer, who makes their own food. Only plants have this ability. Another way is being a consumer, who eats other organisms for food and energy. An example of a consumer would be animals and humans. Lastly, another way organisms can get food is being a decomposer, one who eats dead plants or animals. Decomposers are mostly bacteria, fungus, or invertebrates. A food web is a series or organisms related by predator-prey and consumer resource interactions. It is entirety of irrelated food chains in an ecological community. There is also a trophic level.
