Ch 5 - Populations

The red area on the map shown below represents places where prairie dogs can be found. This represents the animal's:

• biological niche
• geographic range
• population density
• age structure

The number of individuals in a population in a given area is :

• carrying capacity
• density
• distribution rate
• growth rate

A farmer stocks a small pond with catfish. The first year, he caught 10 fish. The following year, he caught 20 fish. In the third year, there are no fish in the pond. What is the most likely explanation?

• the fish were killed by predators
• the fish depleted the resources in the pond
• the fish migrated to another pond
• the fish died over the winter

Which of the following is a density independent factor for snails living in a small pond?

• food availability
• oxygen levels in the pond
• weather and climate conditions
• egg laying locations

Male cardinals act aggressively toward other male cardinals that come into their territory. This is:

• limiting factors
• predator-prey relationship
• intraspecific competition
• interspecific competition

Which term refers to the maximum number of individuals that a particular environment can support?

• expential growth
• logistic growth
• carrying capacity
• rate of density

If a population grows larger than its carrying capacity, what will most likely happen?

• death rates will rise
• death rates will fall
• birth rates will rise
• birth rates will fall

If the birth rate and death rate in the population are equal, what is the GROWTH RATE of the population?

• positive
• negative
• zero
• infinite

Generally speaking, as the number of predators increase in the system, the number of prey:

• increases
• decreases
• stays the same

What type of growth does the graph below represent?

• limiting capacity growth
• exponential growth
• logistic growth
• restrictive growth
