ecology; what is it's purpose? - correct answer ✔✔-study of how organisms interact with their

-to understand the distribution and abundance of organisms
population - correct answer ✔✔group of individuals of the same species living in the same area, at the
same time
community - correct answer ✔✔consists of species that interact with one another within a particular
area
ecosystem - correct answer ✔✔consists of all organisms in a particular region, along with non-living
components
abiotic components - correct answer ✔✔air, water, and non-living parts of soil
range - correct answer ✔✔geographical distribution; abiotic & biotic determine range
biomes - correct answer ✔✔major groupings of plant and animal communities defined by a dominant
vegetation type
climate - correct answer ✔✔the prevailing, long-term weather conditions found in an area
tropical wet forests (rain forests) - correct answer ✔✔found in equator regions where temperatures are
