Population Ecology 1

Which phase represents exponential growth?

• Phase A

• Phase B

• None of the above

• All of the above

Which phase of the graph represents carrying capacity?

• Phase A

• Phase B

• None of the above

• All of the above

Which factor is LEAST LIKELY to impact the carrying capacity of the cacti populations?

• An increase in the number of foxes eating the cacti in the area.

• A decrease in the number of foxes eating the cacti in the area.

• An increase in the amount of rain.

• All of the above will impact the carrying capacity of the cactus population

The maximum number of organisms that an environment can sustain is referred to as:

• Carrying Capacity

• Niche

• Trophic Level

• Biodiversity

• 
• 

Which of the following is NOT a density-independent limiting factor?

• Climate

• Natural Disaster

• Disease

• Weather

Which is NOT an example of a limiting factor.

• Climate
• Available Food & Water
• Available Space & Shelter
• Species color

When a specific population grows past the ecosystem's carrying capacity, what happens to the population?

• Density Independent limiting factors start to occur resulting in the population going farther above carrying capacity.
• Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity
