. The interactions of an organism with its environment are vital to its survival, and the functioning of the ecosystem as a whole. Nothing to be honest, well if they are in a larger space, because increasing the size of a community will increase the number of all organisms, meaning that competition may not really be affected. Seeking matter and energy resources to sustain life, organisms in an ecosystem interact with one another in complex feeding hierarchies of producers, consumers, and decomposers, which together represent a food web. If an herbivore kills the plant, the interaction is similar to predation. 1996 - 2023 National Geographic Society. "An individual is one organism and is also one type of organism(species)".

Elizabeth Wolzak, National Geographic Society, Mark H. Bockenhauer, Ph.D., Associate Professor of Geography, St. Norbert College Symbiosis occurs when there is a very close ecological association between species. Biotic factors include plants, animals, and other organisms.Abiotic factors include rocks, temperature, and humidity.
