Biochemical cycles

Front

What is the greatest contributor to atmospheric carbon?

Back

Transportation is the greatest contributor to atmospheric carbon due to emissions from vehicles.

Front

How do living organisms return carbon to the atmosphere in the carbon cycle?

Back

Living organisms return carbon to the atmosphere through decomposition and respiration.

Front

What is an algal bloom?

Back

An algal bloom is the rapid growth of a population of algae, often due to excess nutrients in water.

Front

What role do decomposers play in the phosphorous cycle?

Back

Decomposers return phosphorous into the soil by breaking down organic matter.

Front

What happens during precipitation in the water cycle?

Back

Precipitation occurs when clouds become too heavy and release water in the form of rain, snow, or hail.

Front

Define the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide back into the atmosphere.

Front

What is the significance of decomposers in ecosystems?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting plant growth.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and runoff.
