Question 8

Match each definition to the correct term
-A certain herbivore selectively destroys some types of plants on rangeland but not others. After those animals have left the area, those tasty plants no longer grow on the plot of land, so we would say that this has been reduced there.

Accepted Answer

Carrying capacity refers to the maximum number of individuals of a particular species that an environment can support sustainably over time, given the food, habitat, water, and other necessities available in the environment. When certain herbivores selectively consume and destroy some types of plants but not others, leading to those plants no longer growing in the area, it can alter the carrying capacity of the environment for those and possibly other species by reducing the availability of resources.
