Question

multiple-choice question
what are density dependent limiting factors?
factors that limit the size of the population based on how large the organism is
factors that limit the size of the population based on the density of the population itself
factors that limit the size of the population because they are too near the carrying capacity

Explanation:

To determine the correct answer, we analyze the definition of density - dependent limiting factors. Density - dependent limiting factors are those that have an impact on a population's size and growth rate in a way that is related to the population's density (the number of individuals per unit area or volume).

• The first option says the factors are based on the size of the organism, which is not related to population density, so it is incorrect.
• The second option states that the factors limit the population size based on the density of the population itself, which matches the definition of density - dependent limiting factors.
• The third option refers to factors related to being near the carrying capacity, but this is not the defining characteristic of density - dependent factors (density - independent factors can also be related to carrying capacity in a different way, and the description here is not accurate for density - dependent factors).

Answer:

B. factors that limit the size of the population based on the density of the population itself
