It explores different scales, from individual organisms to populations, communities, ecosystems, and the biosphere. Each level offers unique insights into the complex, often balanced systems that form our world. Ecology also considers potential biospheres beyond Earth.

Would it be upright? Or inverted? Watch the series of videos to understand about ecological pyramids.
