When describing a community, a biologist would discuss
a. every population that lives together in an area.

b. biome that exists in the biosphere.

c. every organism that can produce offspring together.

d. every ecosystem that is part of a biome.

The right option is; A. every population that lives together in an area.

A community is a group of living organisms inhabiting the same region (such as town, country, or village) or in virtual space (such as the scientific community) and interacting with each other. In a community, organisms share similar characteristics such as language, norms, manners, religion, identity, values and law.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
