EOC Review- Unit 3- Cell Energy, Energy Flow, and Cycles

Front

What gases must remain in balance for plants to carry out cellular respiration and photosynthesis in a terrarium?

Back

Oxygen and carbon dioxide must remain in balance.

Front

What gas is produced by the plant elodea when exposed to sunlight?

Back

Oxygen.

Front

What percentage of energy is typically passed from one trophic level to the next higher trophic level in an ecosystem?

Back

On average, 10% of energy is passed to the next higher trophic level.

Front

How can carbon dioxide (CO2) be reused within the food web?

Back

It can be used by plants during photosynthesis to create glucose.

Front

What energy source is produced during cellular respiration when glucose is broken down?

Back

ATP.

Front

What is photosynthesis?

Back

The process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

The process by which cells break down glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil.

Front

What is the primary source of energy for most ecosystems?

Back

The sun.

Front

What is a food chain?

Back

A linear sequence of organisms through which nutrients and energy pass as one organism eats another.
