Lesson Summary
Understand the levels from individual organisms to the entire biosphere.
Explanation
Ecology is organized in levels from small to large. An individual organism is the smallest level. A population is a group of the same species living in one area. A community includes all the different species in that area. An ecosystem adds in the nonliving parts like water, soil, and climate. A biome is a large region with similar climate and organisms. The biosphere is the entire zone of Earth where life exists. Each level builds on the one before it.
