Ecosystems support complex communities of organisms, where each has an important role to play. Plants carry out photosynthesis, generating oxygen and food for other species; insects and other animals pollinate flowers, enabling new plants to grow; fungi and microorganisms help cycle nutrients through the ecosystem by decomposing dead material; and predators regulate food webs by keeping populations of other animal species in check. Explore the community dynamics of organisms in Nevada ecosystems and how species interactions make important ecological processes and functions possible.
