Ecology 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)
