Deer Population Dynamics and Environmental Influences

The video explores the decline in deer population at a hunting spot over the past decade. It introduces two key ecological concepts: limiting factors and carrying capacity. Limiting factors such as reduced food sources, lack of water, increased coyote population, and hunting pressure have decreased the area's carrying capacity, which is the environment's ability to sustain a population. The video explains how these factors have led to fewer deer in the area.

What has happened to deer hunting behind the narrator's house over the last 10 years?

• It has improved significantly.

• It has declined.

• It has become illegal.

• It has remained the same.

What are limiting factors in the context of deer population?

• Factors that increase population growth.

• Factors that only affect plant growth.

• Factors that decrease population growth.

• Factors that have no effect on population.

Which of the following was NOT mentioned as a food source for deer?

• Wheat

• Soybeans

• Alfalfa

• Corn

What happened to the pond that affected the deer population?

• It was turned into a swimming pool.

• It was expanded.

• It was filled with water.

• It dried up and filled with cattails.

How has the coyote population affected the deer population?

• Coyotes have decreased, helping the deer.

• Coyotes have increased, preying on deer.

• Coyotes have no effect on deer.

• Coyotes have become pets for the deer.

What is meant by 'carrying capacity'?

• The speed at which deer can run.

• The number of hunters allowed in an area.

• The environment's ability to sustain a population.

• The maximum weight a deer can carry.

What was the carrying capacity of the land 10 years ago?

• Low, due to many limiting factors.

• Unchanged from today.

• Non-existent, as there were no deer.

• High, with plenty of resources and few predators.

How do limiting factors affect carrying capacity?

• They have no effect on carrying capacity.

• They increase carrying capacity.

• They decrease carrying capacity.

• They make carrying capacity irrelevant.

What happens to carrying capacity when limiting factors are low?

• Carrying capacity remains the same.

• Carrying capacity decreases.

• Carrying capacity increases.

• Carrying capacity becomes unpredictable.

Which of the following is NOT a limiting factor mentioned in the video?

• Hunting pressure

• Weather conditions

• Water sources

• Food availability
