Ecosystems Unveiled: Understanding Organisms Populations Communities and Components

Miss Heaney introduces the concept of ecosystems, explaining the different levels: organisms, populations, communities, and ecosystems. An organism is a single living thing, exemplified by an antelope. A population consists of multiple organisms of the same type, like a group of antelopes. A community includes all living parts of an ecosystem, such as animals and plants. Finally, an ecosystem comprises both living and non-living elements, including water, rocks, and soil. The video aims to clarify these concepts for better understanding.
