What is the process in which carbon atoms are cycled between abiotic and biotic factors on Earth?

• Photosynthesis

• Respiration

• Carbon cycle

• Geosphere

Answer explanation

The carbon cycle is the process where carbon atoms are exchanged between abiotic (non-living) and biotic (living) components of the Earth, including processes like photosynthesis and respiration, making it the correct answer.

Where is carbon dioxide dissolved and released as oxygen by plankton?

• Atmosphere

• Hydrosphere

• Biosphere

• Geosphere

Answer explanation

Carbon dioxide is dissolved in the hydrosphere, which includes oceans and water bodies. Plankton, through photosynthesis, release oxygen in this environment, making the hydrosphere the correct answer.

What process do plants use to create their own food using sunlight?

• Respiration

• Carbon cycle

• Photosynthesis

• Geosphere

Answer explanation

Plants use photosynthesis to convert sunlight, carbon dioxide, and water into glucose and oxygen, making it the correct process for creating their own food.

Which process involves cells obtaining energy by combining glucose and oxygen?

• Photosynthesis

• Respiration

• Carbon cycle

• Hydrosphere

Answer explanation

Respiration is the process where cells obtain energy by breaking down glucose in the presence of oxygen, producing carbon dioxide and water as byproducts. This is essential for cellular energy production.

What moves between the atmosphere and ocean?

• Oxygen

• Nitrogen

• Carbon

• Hydrogen

Answer explanation

Carbon moves between the atmosphere and ocean through processes like photosynthesis and respiration, making it a key element in the carbon cycle. Unlike oxygen, nitrogen, and hydrogen, carbon specifically cycles between these two environments.

What is the role of the biosphere in the carbon cycle?

• Stores carbon in rocks

• Releases carbon dioxide into the atmosphere

• Involves photosynthesis and respiration between plants and animals

• Dissolves carbon dioxide in water

Answer explanation

The biosphere plays a crucial role in the carbon cycle by involving photosynthesis and respiration. Plants absorb carbon dioxide during photosynthesis, while animals release it through respiration, maintaining the carbon balance.

Through what do carbon atoms move when animals eat plants?

• Atmosphere

• Food web

• Hydrosphere

• Geosphere

Answer explanation

Carbon atoms move through the food web when animals eat plants, as they transfer energy and nutrients from one organism to another, illustrating the interconnectedness of ecosystems.

How does carbon move from living things into the atmosphere?

• Through the geosphere

• By burning fossil fuels

• Through photosynthesis

• By dissolving in water

Answer explanation

Carbon moves from living things into the atmosphere primarily by burning fossil fuels, which releases stored carbon as CO2. Other processes like photosynthesis and dissolving in water do not directly transfer carbon to the atmosphere.

Where is carbon stored in rocks and soil?

• Atmosphere

• Hydrosphere

• Geosphere

• Biosphere

Answer explanation

Carbon is primarily stored in the geosphere, which includes rocks and soil. This storage occurs in the form of carbonates and organic matter, making the geosphere a significant carbon reservoir.

What happens to carbon when fossil fuels are burned?

• It moves to the soil

• It moves to the atmosphere

• It dissolves in water

• It is stored in rocks

Answer explanation

When fossil fuels are burned, carbon is released into the atmosphere as carbon dioxide (CO2), contributing to greenhouse gas emissions and climate change.
