Populations

Question 5 • Science 7 B (M12 25/26 S2)

Natural disasters, like an earthquake, can be a limiting factor to population growth. Which is an example of a natural disaster limiting population growth?

Answer
A
A zebra population being attacked by different lion herds.
B
Space in a forest becomes crowded, and a population of low-lying plants cannot get enough sunlight.
C
A strong thunderstorm destroys many of the nests of a bird population.
D
A month of colder air in the spring delays the growth of plants that provide food for a deer population.

Explanation

A natural disaster is a severe natural event that directly harms a population. A strong thunderstorm destroying many bird nests can reduce the number of birds that survive or reproduce, limiting population growth. Crowding and competition for sunlight in B are limiting factors, but they are not natural disasters.
