Living things need to interact with other living and nonliving things in an ecosystem to obtain resources such as food, water, and shelter, to reproduce, and to maintain balance in the ecosystem. These interactions also help in nutrient cycling, energy flow, and maintaining biodiversity within the ecosystem.
- The organisms have to fit into the energy pyramid- The largest number of organism in any ecosystem needs to be the producers- The smallest number of organism need to be the highest level of consumers in that ecosystem
