Question 4 • Earth and Space A 26-27

Which statement describes a scenario where limited availability of an environmental resource leads to competition among plants?

Answer
A
Organisms share a place to sleep.
B
A living thing consumes berries on a tree.
C
Sunlight shines only three months out of the year.
D
A stream supplies an abundance of water in a forest.

Explanation

Plants need sunlight to grow, and if it is available for only three months of the year, it is limited. Plants may compete with one another to get enough sunlight during that period. An abundant supply of water, as in choice D, would not describe a limited resource.
