Mini CBA Review

Front

What is the energy transfer efficiency from producers to herbivores in a trophic level?

Back

Typically, only about 10% of the energy from producers (trophic level 1) is transferred to herbivores (trophic level 2). If there are 1000 Kcal in producers, there would be approximately 100 Kcal available for herbivores.

Front

What is a decomposer?

Back

A decomposer is an organism that gets energy by breaking down dead organisms, non-living material, or waste.

Front

What determines the boundaries of a watershed?

Back

The boundaries of a watershed are determined by elevation.

Front

Which model best represents how water flows in a watershed?

Back

Model D best represents how water flows in a watershed.

Front

Which level of a pyramid of energy contains members of the plant kingdom?

Back

Level D of the pyramid of energy contains members of the plant kingdom.

Front

Define a producer in an ecosystem.

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, serving as a primary energy source in an ecosystem.

Front

What is a consumer?

Back

A consumer is an organism that obtains energy by eating other organisms, including plants and animals.

Front

Explain the role of elevation in ecosystems.

Back

Elevation affects climate, vegetation, and water flow, influencing the types of organisms that can thrive in a particular area.

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 from one level to the next.

Front

What is the significance of energy pyramids in ecosystems?

Back

Energy pyramids illustrate the energy transfer between trophic levels, showing that energy decreases as it moves up the pyramid.
