Ecology Review #2

Front

What is a pyramid of energy in an ecosystem?

Back

A graphical representation showing the flow of energy through different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to higher trophic levels.

Front

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

Back

The base level (Level D) contains producers, which are primarily plants.

Front

What happens to energy as you move up an energy pyramid?

Back

Energy decreases as you move up the pyramid.

Front

What is a decomposer?

Back

An organism that breaks down dead organisms, non-living material, or waste, returning nutrients to the ecosystem.

Front

What is an autotroph?

Back

An organism that can produce its own food through photosynthesis or chemosynthesis.

Front

If there is 1000 Kcal available in the producers, how much energy is available in the herbivores?

Back

100 Kcal is available in the herbivores in trophic level 2.

Front

What is a consumer?

Back

An organism that obtains energy by consuming other organisms.

Front

What is the difference between a herbivore and a carnivore?

Back

A herbivore eats plants, while a carnivore eats other animals.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers recycle nutrients back into the soil, making them available for producers.

Front

What is the primary source of energy for most ecosystems?

Back

The sun is the primary source of energy for most ecosystems.
