Unit 1 Ecology Test Review 24-25

Front

What is the most effective solution for reducing greenhouse gas emissions?

Back

Reducing production of carbon dioxide by increasing the use of public transportation.

Front

What are limiting factors that impact population size regardless of population density?

Back

Density Independent Limiting Factors.

Front

What happened to the elk population after the reintroduction of gray wolves to Yellowstone?

Back

The elk population began to decline.

Front

What type of symbiotic relationship exists between humans and plants in the process of cellular respiration and photosynthesis?

Back

Mutualism.

Front

Why are there fewer organisms at higher trophic levels in an energy pyramid?

Back

Energy is used and lost as heat moving from one trophic level to the next.

Front

What is the definition of carrying capacity in an ecosystem?

Back

The maximum population size that an environment can sustain indefinitely.

Front

What is the role of producers in an ecosystem?

Back

Producers convert solar energy into chemical energy through photosynthesis.

Front

What is the difference between density-dependent and density-independent limiting factors?

Back

Density-dependent factors are influenced by population size, while density-independent factors affect populations regardless of size.

Front

What is an example of a density-independent limiting factor?

Back

Natural disasters such as floods or wildfires.

Front

How do predators affect the population of their prey?

Back

Predators can decrease the population of prey species, which can lead to changes in the ecosystem.
