FLASHCARD QUESTION

Front

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

Back

Energy decreases as you move up the pyramid due to energy loss at each trophic level, primarily through metabolic processes and heat.

FLASHCARD QUESTION

Front

What do the arrows in an energy pyramid represent?

Back

The arrows represent the direction of energy flow from one trophic level to the next.

4.

FLASHCARD QUESTION

Front

What is the primary source of energy in an energy pyramid?

Back

The primary source of energy in an energy pyramid is sunlight, which is captured by producers (plants) through photosynthesis.

FLASHCARD QUESTION

Front

If there are 1000 Kcal in producers, how much energy is typically available to primary consumers?

Back

Typically, only about 10% of the energy (100 Kcal) is transferred to primary consumers (herbivores) from producers.

FLASHCARD QUESTION

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or energy pyramid that indicates the organism's role in the flow of energy, such as producers, primary consumers, secondary consumers, etc.
