Ecology is the study of the interactions among living things and their surroundings How do organisms relate to each other? How does the environment relate to organisms?

Ecology + Organization Ecology organizes biotic and abiotic factors into levels of complexity BIOTIC – living things ABIOTIC – nonliving things

Examples of biotic factors? Examples of abiotic factors? Abiotic factors balance and change what biotic factors can survive

Ecology + Organization The 1 st, most simple level is the single organism Example: In a swamp in the Florida Everglades, a single turtle

Ecology + Organization 2 nd Level: The Population A group of the same species that live together in one area Example: All the turtles in the swamp

Ecology + Organization 3 rd Level: The Community A group of different species that live together in one area Example: the turtles, alligators, birds, fish, and plants in the swamp

Ecology + Organization 4 th Level: The Ecosystem All the organisms and all the abiotic factors (soil water, climate, rocks, etc. ) in one area Ecosystems can vary in size and be nested (one ecosystem inside another)

Ecology + Organization 5 th Level: The Biome A major regional or global community of organisms Biomes are characterized by the climate conditions and communities that thrive there

Ecology + Organization 6 th (Last, most complicated) Level: The Biosphere All the ecosystems on Earth (everywhere life exists)
