Which process releases carbon dioxide into the atmosphere?

Respiration

Explanation

Biological process of breathing by organisms releases CO2.

What is the primary reservoir of carbon in the carbon cycle?

Oceans

Explanation

Oceans store the most carbon.

Which of the following is not a greenhouse gas?

Carbon monoxide (CO)

Explanation

CO is not a greenhouse gas, unlike CO2.

What is the term for the process by which plants release water vapor into the atmosphere?

Transpiration

Explanation

Plants release water vapor through transpiration.

What is the primary way carbon dioxide is removed from the atmosphere?

Photosynthesis

Explanation

Plants absorb CO2 during photosynthesis.

Which human activity contributes significantly to the increase in atmospheric carbon dioxide levels?

Deforestation

Explanation

Clearing forests reduces CO2 absorption.

Which molecule is responsible for trapping heat in the Earth's atmosphere, contributing to the greenhouse effect?

Carbon dioxide (CO2)

Explanation

CO2 traps heat, enhancing the greenhouse effect.

What is the term for the process by which carbon is transferred from living organisms to the soil?

Decomposition

Explanation

Organic matter breakdown enriches soil with carbon.

In the carbon cycle, what process returns carbon from the atmosphere to the Earth's surface?

Precipitation

Explanation

Rain carries CO2 from atmosphere to Earth.

#10

Which factor influences the rate of carbon dioxide absorption by oceans?

Water temperature

Explanation

Warmer water absorbs CO2 less efficiently.

#11

What role do decomposers play in the carbon cycle?

Releasing carbon dioxide

Explanation

Decomposers break down organic matter, releasing CO2.

#12

Which geological process involves the long-term storage of carbon in sedimentary rocks?

Fossilization

Explanation

Organic matter forms fossil fuels over eons.

#13

Which biome stores the largest amount of carbon in its soil?

Tropical rainforest

Explanation

Tropical rainforests have rich carbon stores.

#14

Which process is responsible for converting organic matter into fossil fuels?

Fossilization

Explanation

Organic matter burial leads to fossil fuel formation.

#15

What role do phytoplankton play in the carbon cycle?

Absorbing carbon dioxide

Explanation

Phytoplankton sequester CO2 through photosynthesis.
