Question

Which of the following is NOT true of the global human population? A. Humans have exceeded their carrying capacity B. The human population is currently growing C. In the past, humans increased their capacity through advances medicine D. Most population growth is in developing countries In nature, at most times, most populations: A. Are at or near their carrying capacities B. Are far above their carrying capacities C. Are far below their carrying capacities D. Do not have a carrying capacity K-selected populations reproduce: A. Rapidly and gradually approach their carrying capacity B. Rapidly and overshoot their carrying capacity C. Slowly and gradually approach their carrying capacity D. Slowly and overshoot their carrying capacity In nature, growth of a population beyond its carrying capacity leads to: A. Population growth but at a slower pace B. An increase of the carrying capacity C. Extinction the population D. Deaths in the population until carrying capacity is reached Population growth seen in most natural populations is logistic growth A. Slow, steady growth that eventually levels out B. Rapid growth that eventually slows and then levels out C. low, steady growth that never levels out D. Rapid growth that never slows or levels out carrying capacity of a population is: The number of individuals currently in a population The range of ages of individuals in a population The geographical distribution of a population The maximum number of individual in

Explanation / Answer

30.

Option C

Carrying capacity depends on the ecosystem, but not on the life expectancy improvement of humans.

31.

Option A.

In nature, most populations are at or near their carrying capacity.

32.

Option C

K-selected species show S-shaped logistic growth curve that slowly and gradually approaches carrying capacity.

33.

Option D

If the population exceeds carrying capacity, ecosystem can not support their growth. So, deaths in the population occur until carrying capacity is reached.

34.

Option A

Population growth in natural conditions is logistic growth - Slow, steady growth that eventually levels out due to limited resources.

35.

Option D

Carrying capacity is the maximum number of individuals of a population that an ecosystem can sustain.
