Use examples to explain how changes to both living and non living parts of an ecosystem can affect individuals and populations.

Living Things in an Ecosystem Example - In a pond, for example, living organisms range in size from the algae and zooplankton in a drop of pond water to the larger fish, amphibians, lilies and cattails that make their homes in the pond. All the different populations of species co-existing and thriving within that same environment define the inhabitants of an ecosystem. The resilience of the community hinges on a cycle - - or chain of events and processes - - that creates food and energy for all the organisms within the community.

Non Living - The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks, water, soil, light, rocks etc.
