Ecology Flashcards
study of organisms AND their interactions with their environment
ECOLOGY
non living things (water, soil, wind, etc.)
ABIOTIC
living things (plants, animals, etc.)
BIOTIC
individual within a species
ORGANISM
all members of the same species in one area
POPULATION
several populations living and interacting with each other in one area
COMMUNITY
a community plus the abiotic factors
ECOSYSTEM
many similar ecosystems within a large area
BIOME
all biomes of the world
BIOSPHERE
process where plants take in H2O, CO2, and light to produce sugar and O2
PHOTOSYNTHESIS
process that all non plants take in sugar and O2 and produce H2O, CO2, and give off heat
CELL RESPIRATION
has effect on population but is out of organisms control
DENSITY-INDEPENDENT FACTOR
has effect on population because of its high density
DENSITY-DEPENDENT FACTOR
how many organisms there are in 1 kilometer
POPULATION DENSITY
how a population of an organism is organized
POPULATION DISTRIBUTION
