The Carbon Cycle Flashcard

Front

What gas is released into the atmosphere during photosynthesis?

Back

Oxygen is released into the atmosphere during photosynthesis.

Front

What is the main source of carbon for plants during photosynthesis?

Back

The main source of carbon for plants during photosynthesis is carbon dioxide.

Front

What process returns carbon to the atmosphere as carbon dioxide?

Back

Respiration is the process that returns carbon to the atmosphere as carbon dioxide.

Front

What is the process responsible for breaking down organic matter into simpler compounds?

Back

Decomposition is the process responsible for breaking down organic matter into simpler compounds.

Front

What do bacteria release back into the atmosphere when they decompose dead plants?

Back

Bacteria release carbon back into the atmosphere when they decompose dead plants.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere.

Front

Explain the significance of respiration in the carbon cycle.

Back

Respiration is significant in the carbon cycle as it releases carbon dioxide back into the atmosphere, which is then used by plants for photosynthesis.

Front

What is combustion and how does it relate to the carbon cycle?

Back

Combustion is the process of burning fossil fuels, which releases carbon dioxide into the atmosphere, contributing to the carbon cycle.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis, providing the carbon needed to produce glucose.
