[edit] Ecosystem-based mechanisms
In ecosystems the amount of resources available and how much of those resources are utilized by organisms, determine the effects of new additions to the ecosystem.

Ecosystem services are things that natural ecological systems, ecosystems, provide for human beings, and they include things like filtering water, purifying water, purifying the air.

Nonetheless, plants are the basis for the Earth's ecosystem and food web, and without them complex animal life forms (such as humans) could never have evolved.

Overall, microorganisms are some of the most important living creatures. Their roles as producers and recyclers makes them vital in most ecosystems.

organisms, cells form tissues (example, muscle), tissues form organs (example, heart), and several organs function as an organ system (example, circulatory system). Organisms form populations, populations form communities, communities form ecosystems.
