E.S. L 2-2 Cycles of Matter

Front

What is the role of oxygen in the cycles of matter?

Back

Oxygen is essential for respiration in living organisms and is produced during photosynthesis by plants.

Front

What is the Water Cycle?

Back

The Water Cycle is the continuous movement of water on, above, and below the surface of the Earth, including processes like evaporation, condensation, and precipitation.

Front

Define evaporation in the context of the Water Cycle.

Back

Evaporation is the process where water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is condensation in the Water Cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from clouds to the Earth's surface, including rain, snow, sleet, and hail.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter and return nutrients to the soil.

Front

What nutrients do decomposers return to the soil?

Back

Decomposers return carbon and nitrogen to the soil.

Front

What are legumes?

Back

Legumes are plants that have a symbiotic relationship with nitrogen-fixing bacteria, often found in their root nodules.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen into a form that plants can use.

Front

What is the difference between carbon dioxide and oxygen in the context of photosynthesis?

Back

Plants take in carbon dioxide and release oxygen during photosynthesis, which is essential for life on Earth.
