Question

What is expected to happen to the death rate as population density and competition increase?

Answer 1

As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).

Answer 2

Answer: a. decreases

Explanation:

A population density can be define as the number of individuals in a population of a species living in a unit of area in a particular time. The population density can be influenced by number of births, deaths, immigration, emigration and competition. The number of live birth in a concerned population and immigration (introduction of the new members) are likely to increase the population density of a region. But the number of deaths and emigration (the members of the same population move to a new habitat), and the competition (the members of the same species may compete among themselves for the same resources, the superior one will receive the resources and the inferior one will loose and may die) will decrease the population density.

According to the given situation, death rate and competition among the individuals will likely to decrease the population density.
