Biosphere - ANS ✔✔Consists of all life on Earth and all parts of the Earth in which life exists,
including land, water, and the atmosphere.
biome - ANS ✔✔A group of ecosystems that share similar climates and typical organisms
ecosystem - ANS ✔✔A system formed by the interaction of a community of organisms with
their physical environment
community - ANS ✔✔assemblage of different populations that live together in a defined area
populations - ANS ✔✔groups of individuals that belong to the same species and live in the
same area
Niche vs. Habitat - ANS ✔✔The role a species plays in the ecosystem is called its niche. A habitat
is the physical environment in which a species lives.
movement of energy ecosystems - ANS ✔✔sun > producers > consumers > decomposers
three broad categories of biomes - ANS ✔✔terrestrial, freshwater, marine
what is biosphere 2? - ANS ✔✔the experiment in Arizona attempting to make an independent
second biosphere
, what was one success of biosphere 2? - ANS ✔✔they successfully stayed inside for the duration
