2 ECOLOGY - the study of interactions between organisms and with their environment

3 BIOSPHERE - portion of planet where life exists
BIODIVERSITY – sum total of all the different kinds of organisms living in an area. It is affected by changes in habitats Habitat- place where a particular population of species lives e.g. top of a tree for some birds, Bottom of a tree for other birds, Ayala High is the habitat of Bulldogs

4 LEVELS OF ORGANIZATION Organism  individual living thing Species - individuals that can breed with one another and produce fertile offspring e.g. horse with horse = horse; horse with donkey = mule, which is NOT fertile (so horse & donkey not in same species Population - all the individuals of the same species (e.g. ducks) in a given area

5 A population is always composed of the same species of organisms
e.g. Rubber duckies

6 Community - all the populations that live together in an area e. g
Community - all the populations that live together in an area e.g. water plants, fish, turtle, grasses, insects, birds, racoons, etc.

7 An ecosystem includes both biotic and abiotic factors in an area Biotic factors are  things that live (e.g. plants, animals, fungi, bacteria) Abiotic factors are  nonliving things (e.g. water, wind, temperature, amount of sunlight, soil type, etc.) e.g. (Examples): Rotting Log Koi Pond Lake Clump of Dirt A field An old maple tree

8 An ecosystem includes both biotic & abiotic factors Biotic factors are living things (plants, animals, bacteria, etc.) Abiotic factors are nonliving things (how much water, temperature, wind, sunlight, soil type, etc.)

9 Biome - large area that has a particular climate, and particular types or species of plants and animals that live there (e.g. tundra, desert, etc)

10 Biosphere - the part of the earth that supports life

11 Levels of Organization
Biosphere Label these levels of Organization in their correct sequential order Ecology: Levels of Organization (Organisms, Communities, Biomes, biosphere) Biome Ecosystem Community Individual organism Population Species
