    SchoolCenter Picture

    • The living organisms within a specific area and their physical environment define an ecosystem.

    • The major terrestrial ecosystems are classified into units called biomes - large regions characterized by certain conditions, including a range of climate and ecological communities adapted to those conditions.

    • Organisms have specific structures, functions, and behaviors that enable them to survive the conditions of the particular ecosystem in which they live.

    • Organisms adapt to both biotic and abiotic factors in their ecosystem.
