population density
birth rate
death rate
population
The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. What factors would increase a carrying capacity for a population?
I. habitat loss
II. increase in food sources
III. access to clean water
IV. increase in competition
V. increase in diseases
II & III
I, II, & V
III & IV
II, IV, & V
Consider the wetland habitat pictured here. Imagine a very hot summer with little rain. What would be the limiting factor for the populations of all of the animals living here?
competition
food
space
water
This squirrel lives in a forest and eats only acorns. What will MOST LIKELY happen to the squirrel if the oak trees in this forest start dying of a disease?
The squirrel will adapt to less food.
The squirrel will not be affected at all.
The squirrel will starve if it can't find enough food.
The squirrel will eat berries instead of acorns to survive.
Which pattern below shows a clumped dispersion of a population?
Pattern A
Pattern B
Pattern C
If the number of births in a population is higher than the number of deaths in a population, what will happen to the growth of the population?
it will increase
it will decrease
it will stay the same
it will fluctuate
What factor describes when populations decrease because animals are moving out of a population?
emigration
immigration
abandonment
succession

Which of the following shows species population in an environment where there is no limiting factor?
Define "carrying capacity"
any factors in an environment that are limited
when population increases slowly at first then grow at an accelerated rate

uniform dispersion
clumped dispersion
random dispersion
