Three Key Questions in Population Ecology

This video tutorial covers three population ecology questions to aid GED science preparation. It explains the concept of carrying capacity, competition levels at carrying capacity, and the impact of predators on carrying capacity using graphs. The video emphasizes the importance of understanding these concepts for GED test success and offers tips for interpreting graphs and charts.

What does the y-axis represent in the graph shown in the video?

• Predator population

• Carrying capacity

• Number of organisms

• Time

At point one in the graph, what is happening to the population?

• Staying the same

• Increasing

• Decreasing

• Reaching carrying capacity

What is carrying capacity?

• The minimum number of organisms needed for survival

• The average population size an environment can sustain

• The maximum number of predators in an environment

• The total number of species in an ecosystem

What happens to competition between individuals when an animal reaches carrying capacity?

• Competition is low

• Competition is non-existent

• Competition is high

• There is an excess of resources

What would happen to the carrying capacity of an animal if a predator is introduced?

• The predator would have no effect

• It would decrease

• It would stay the same

• It would increase

What is likely to happen to the population of elk or deer if predators are introduced?

• The population will decrease

• The population will not be affected

• The population will stay the same

• The population will increase

Why do test makers prefer questions involving graphs and charts?

• They test the ability to read and interpret data

• They take less time to answer

• They are more interesting

• They are easier to grade

What is the main focus of the video?

• Chemical reactions

• Physics principles

• Population ecology and carrying capacity

• Mathematical equations
