Question

question 2 of 10
which item is an example of a community?

a. a lake and all of the animals and plants that live near it
b. a herd of deer and the animals and plants it interacts with
c. a flock of geese flying south for the winter
d. all of the garter snakes that are alive on earth at a
specific time

Explanation:

To determine a community, we recall that a community consists of all the different populations (of various species) that interact in a particular area.

• Option A: A lake and its nearby organisms include the abiotic lake and biotic components, which is an ecosystem (not just a community, as community is biotic only).
• Option B: A herd of deer (one population) plus the other animals and plants (other populations) it interacts with in an area fits the definition of a community (multiple species/populations interacting).
• Option C: A flock of geese is a single population (same species), so it is a population, not a community.
• Option D: All garter snakes on Earth at a time is a single species' population (a metapopulation maybe, but still one species), not a community.

Answer:

B. A herd of deer and the animals and plants it interacts with
