Ultimately, energy that entered the ecosystem as sunlight is dissipated as heat and radiated back into space. Ecosystem ecology considers the interactions between organisms and between organisms and the abiotic components of an area.

On land, plants are major producers. A disturbance of this sort could lead to permanent alteration or loss of the ecosystem. Biotic factors, such as producers and consumers, and abiotic factors, such as the temperature, soil, water and physiographic factors. Levels of Ecology Overview & Examples | Levels of Organization in an Ecosystem - Video & Lesson Transcript | Study.com.

Describe how you are connected with ecosystems, both through the resources that you consume (food, energy, and materials) and through your recreational activities.
