Question 1 Report

Which of the following groups of environmental factors are density-dependent?
Answer Details
Food, predation, disease, and accumulation of metabolites are density-dependent environmental factors. Density-dependent factors are those that become more influential as the population size of a species increases. For example, as a population grows, there may be increased competition for limited food resources, an increase in the spread of disease, and a buildup of waste products, which can all have a negative impact on the population. These factors can limit the growth of a population and help to maintain a balance in the ecosystem.
