question 6
butterflies eat flower nectar and birds eat butterflies. the butterflies, flowers, and birds constitute a(n)___.
a individual.
b population.
c community.

Explanation:

For the first question: Population growth rate depends on the net change from births (adding individuals) and deaths (removing individuals). Carrying capacity affects maximum population size, not the growth rate calculation itself. Birth rate or death rate alone is insufficient—their difference determines growth.
For the second question: A community consists of multiple interacting species in a shared area. Butterflies, flowers, and birds are different species with feeding interactions, so they form a community. An individual is one organism, a population is one species group.

Answer:

First question: B. difference between births and deaths
Second question: C. community.
