Which of the following most accurately defines the term carrying capacity? Multiple Choice An estimate of our individual and collective environmental impacts. A population explosion followed by a population crash. The populations of plants, animals, and microorganisms living and interacting in a certain area at a given time. The maximum number of individuals of a particular species that can be supported by a given ecosystem on a long-term basis. < Prev 1 of 20 Next >

MULTIPLE CHOICE—Select all correct answers. There may be more than one correct answer or no answers may be correct. 4. How did the development of agriculture affect the carrying capacity of the earth for humans, at least temporarily? a. It decreased the carrying capacity. b. The carrying capacity remained the same; nothing can change the carrying capacity of the environment. c. It increased the carrying capacity. 5. Why is the crude birth rate an inaccurate way to measure births? a. because it neglects asexual reproduction b. because it considers children who die of infant mortality during the first year of life c. because it is based on all the individuals in the population d. because it doesn't take into account the fact that in sexually reproducing species like humans, it takes two individuals to produce an offspring 6. Which of the following is an example of an interaction that has negative effects on both populations? a. commensalism b. competition c. mutualism d. parasitism e. predation f. symbiosis 7. When will the global human population reach zero population growth? a. when each woman has only 2 children b. when the human population reaches the carrying capacity of the earth c. when men are the ones who have to be pregnant for 9 months d. when the number of births is equal to the number of deaths 8. If the growth rate in a population is 2.5% per year, what can you determine about the population? a. the age pyramid will be that of an increasing population b. the birth rate is greater than the death rate c. it will show a boom-and-bust population growth d. the population size is already larger than the carrying capacity of the environment e. the doubling time is more than 30 years
'What defines the carrying capacity of a population? Choose All That Apply the maximum number of individuals a particular habitat can support an indicator of the functional requirements that individuals in a population need for growth and reproduction a reflection of the environmental resources that are needed to support a population'
