Exam 11: Intraspecific Population Regulation

Which of the following factors is most likely to be a density-independent regulator of population growth?

No population continues to grow in size indefinitely.

When individuals in a small population have difficulty finding a mate,this is referred to as

The individuals that disperse as a response to high population density are

Within a social group,the ________ individual is dominant over all other members.

The maximum sustainable population size for the prevailing environment is called the ________ capacity.

You see two squirrels fighting over a food resource.This most likely represents

Population density can affect the age at which an animal matures.

The carrying capacity (K)of a population can vary depending on the supply of resources.

What is the minimum dynamic area?

Density-________ growth is the inverse relationship between population density and individual growth.

The carrying capacity is the population size at which dN/dt

As the density of a population increases,dispersal usually decreases.

One hypothesis of population regulation in animals is that increased crowding and social contact cause ________.

Social organization occurs only among invertebrate animals such as ants,bees,and termites.

The part of an animal's home range that is defended against intruders is its ________.

Competition for resources is a density-independent factor affecting a population.

Density-independent population regulation

The factors that influence the growth rate of a population in proportion to the size of the population are called density-________ factors.

You see a plot of plants that is very dense and small and another plot of the same species with fewer individuals but larger individual plants.What might be the cause of this pattern?
