Question

changes in the size of a population of antelope are shown in the table below.
year approximate population
2002 5,996
2003 8,087
2004 11,983
2005 18,264
2006 22,652
2007 17,476
2008 18,652
what is the most likely explanation for the population changes between 2006 to 2007?
choose 1 answer.
a a rainy season led to an increase in plant population sizes in the region.
b an infectious disease decreased the population of leopards that prey on antelope in the region.
c the antelope population overshot the amount that could be supported by the habitat, and many moved or perished.
d as the antelope population reached the carrying capacity, they produced fewer offspring in order to reduce competition.

Explanation:

The antelope population increased from 2002 - 2006 then decreased in 2007. When a population over - shoots the carrying capacity of its habitat, resources become limited. This can lead to migration or death of individuals. Option A would likely cause an increase in antelope population. Option B would also likely increase the antelope population as there are fewer predators. Option D is about a long - term adjustment at carrying capacity, not a sudden decrease. The most likely reason for the sudden decrease in 2007 is that the population overshot the habitat's support capacity.

Answer:

C. The antelope population overshot the amount that could be supported by the habitat, and many moved or perished.
