What are ecosystems?
Levels of Organization of Living Things:
In a natural area, there are individual organisms living together. Groups of organisms of the same species are called populations. Different populations living together form communities. These communities then form ecosystems, biomes, and eventually the entire biosphere.
Answer and Explanation:
An ecosystem is the collection of living and non-living things in an area. Ecosystems encompass multiple communities and the abiotic factors, or non-living things that support them. For example, a forest is an example of an ecosystem. A forest has multiple populations of organisms living there, such as grass, trees, deer, rabbits, foxes, bears and more. It also has non-living factors that support these organisms, such as sunlight, oxygen, water, and nutrients.
