Summary Introduction
Introduction: The density-dependent factors increase with an increase in the population density. The death rate is said to be density-dependent if it rises with an increase in population density. In the same way, the birth rate is said to be density-dependent if it falls with increasing population.

- Make a prediction of how a population of animals behave if the population exceeds the carrying capacity of their habitats.arrow_forwardUse the information and table to answer the following question. An ecologist is studying a population of mosquitos living in a nearby pond. The ecologist estimates the population size twice a day - once at sunrise and once at sunset - for 5 days during the summer when mosquitos are reproducing. Their data is shown. Based on the data, what is the estimated carrying capacity for the population and what factor may have led to a change in data at day three? a. The estimated carrying capacity is approximately 167 thousand. The population may have decreased during day three because of decreased pressure from a limiting factor such as reduction of predators eating the mosquitos. b. The estimated carrying capacity is approximately 188 thousand. The population may have decreased during day three because of decreased pressure from limiting factors, such as more food being available.c.
