EVS Final Exam Review

Front

Which organism would likely have the largest population in a stable ecosystem?

Back

Primary producers are the organisms that would likely have the largest population in a stable ecosystem, as they form the base of the food chain.

Front

What is the primary role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What percentage of energy is typically transferred from one trophic level to the next?

Back

Typically, only 10 percent of energy is transferred from one trophic level to the next in an ecosystem.

Front

What is the primary challenge facing wind energy development?

Back

The primary challenge facing wind energy development is its intermittent nature, meaning it is not continuous or steady.

Front

Which factor most affects the efficiency of photovoltaic cells?

Back

Solar intensity is the factor that most affects the efficiency of photovoltaic cells.

Front

Define primary producers.

Back

Primary producers are organisms, such as plants and algae, that produce energy through photosynthesis.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients.

Front

Explain the role of primary consumers in an ecosystem.

Back

Primary consumers are organisms that eat primary producers; they are herbivores that convert plant energy into a form usable by higher trophic levels.

Front

What is the significance of energy transfer in ecosystems?

Back

Energy transfer is significant because it determines the structure and function of ecosystems, influencing population dynamics and community interactions.

Front

What are decomposers, and why are they important?

Back

Decomposers are organisms that break down dead material, playing a crucial role in nutrient cycling and maintaining ecosystem health.
