Key components within Carbon Cycles

Question 1

Respiration

Answer 1

Animals and other organisms release CO2 into the atmosphere during respiration.

Question 2

Photosynthesis

Answer 2

Plants absorb carbon dioxide (CO2) from the air during photosynthesis, converting it into sugars and oxygen.

Question 3

Decomposition

Answer 3

Carbon in animal wastes and bodies is released as CO2 by decay organisms

Question 4

Decomposers

Answer 4

Decomposers are organisms that break down dead animal matter and dead plants. They are involved in virtually all of the nutrient cycles on the planet.

Question 5

Decomposers Example

Answer 5

There are four types of decomposers: fungi, bacteria, insects, and earthworms.

Question 6

Upwelling

Answer 6

Deeper waters are richer in nutrients, promoting phytoplankton growth.
