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
