Population Ecology (2024)

The number of a given species in one area is called

• population distribution

• population density

• random quadrat sampling

• mark and recapture

The equation for finding population density is

calculate the density of a 30 km² area containing 24 lions

• 0.8 lions per km²

• 1.25 lions per km²

• 720 lions per km²

• 6 lions per km²

a population is...

• a group of one species in one area

• multiple species that live in one area

• all of the living and nonliving things in an area

As a population grows, it will most likely stop growing at the...

• growth limit

• exponential limit

• carrying capacity

• logical limit

A species' carrying capacity (K) of an environment is determined by

• dispersion pattern of the population

• number of offspring per litter for a given species

• supply of the most limited resources

What type of growth is represented in the graph?

• exponential

• logistic

In logistic growth curves, why does the population number increase so quickly before reaching carrying capacity?

• resources are limited

• resources have not become limited yet

• a few resources have run out but most are still plentiful

• organisms aren't using resources to their full advantage

What is the carrying capacity for this population?

• about 50 organisms

• about 15 organisms

• about 800 organisms

• about 5 organisms
