The intensity of competition among animals in a given area will increase with
an increase in the frequency of disease outbreaks
an increase in population size
a decrease in immigration rate
an increase in the emigration rate
Explanation
An increase in population leads to competition because a larger number of individuals vying for the same limited resources (like food, water, mates, or territory) intensifies the struggle for survival and reproduction.
