- density-dependent: depend on population size
abiotic
non-living or inanimate
- density-independent: dont depend on population size
what is a biosphere
the land air and water of earth
- all biomes on earth
what is a species
similar organisms that can breed and produce viable offspring
viable
can have their own kids
what is an individual
an organism from a specific species
what is a population
a population is a group of individuals of the same species
what is a community
all populations of habitat
ecologists
scientist who study the interactions of organisms with one another and their environment
- ex: individuals, populations and ecosystems
individual ecologists
- studies the abiotic factors that can change an individuals behavior or physical features
population ecologists
describe changes in the size of a population, its abundance as time goes by
- why a population changes
what factors determine the relative numbers of males and females in a population
community ecologist
study interactions between the populations/species
> competition between individuals of the same or between species
> abiotic factors that affect the living conditions of populations that live there
- why some communities are more diverse
> competition between individuals of the same or in between species
