APES Chapter 8 True/False

STUDY
PLAY
The size of a species' population, be that animal or human, is influenced by births, deaths, immigration, and emigration.
True
A population will increase in size when it is made up mostly of individuals in the prereproductive age category.
True
No population can grow indefinitely because there is always some limiting factor that keeps a population in check.
True
Carrying capacity (K) is a result of the combination of biotic potential and environmental resistance.
True
Because humans can control over their environment and readily adapt to change, human populations can never experience a population crash.
False
A population's growth rate will increase as the population reaches its carrying capacity.
False
When a population overshoots the environment's carrying capacity, species diversity becomes constant.
False
The human population can continue yielding a J-shaped growth curve because of technology.
False
Carrying capacity is the population size (or density) at which the environment saturated.
True
When a population reaches carrying capacity, the population's biotic potential gradually declines to a consistent values slightly greater than the original.
False
The effect of population increase or environmental resistance is not felt instantly in most cases.
True
It is always an advantage to reproduce sexually.
False
Highly developed countries have such a high population growth rate because the birth rate is so high.
False
K-selected species tend to be opportunists and can fill a niche by reproducing rapidly until carrying capacity is reached.
False
On a survivorship curve, r-selected species tend to demonstrate late loss.
