Ecology Review

If a country has a death rate of 30 and a birth rate of 45 the natural rate of increase would show the population is:

• Increasing
• Decreasing
• Staying the same
• Fluctuating too much

What factor describes when populations increase because animals are moving into a population?

• Emigration
• Limiting Factors
• Immigration
• Exponential Growth

Logistic growth has 3 phases. In Phase 1, the population grows rapidly. In Phase 2, population grows slowly. In Phase 3, growth stops. What causes growth to stop in the 3rd phase of logistic growth?

• Emigration
• Immigration
• Exponential Growth
• Carrying Capacity

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
• None of these

The major human causes of extinction today are

• hunting and destroying habitats.
• polluting and introducing non-native species.
• Both
• Neither

The carrying capacity of an environment for a particular species at a particular time is determined by the

• number of individuals in the species.
• distribution of the population.
• reproductive potential of the species.
• supply of the most limited resources
