Photosynthesis and Carbon Cycle

Front

During photosynthesis, how does molecules inside chloroplasts in plant cells absorb energy from the Sun?

Back

Light energy from the Sun is converted into chemical energy in plant cells.

Front

What is the law of conservation of energy in photosynthesis?

Back

Energy is neither created nor destroyed; it is transformed from light energy to chemical energy.

Front

What is the most accurate statement about carbon on Earth?

Back

A finite amount of carbon exists on Earth, and it moves through living and nonliving materials through the carbon cycle.

Front

How does carbon flow through the food chain?

Back

Carbon flows through the food chain as animals eat, then decomposes and is reused in the system.

Front

How does carbon move in Earth's atmosphere?

Back

Carbon enters Earth's atmosphere when animals exhale and is reused in the atmosphere.

Front

What is the photosynthesis and the law of conservation of mass?

Back

The number of oxygen atoms in the reactants equals the number of oxygen atoms in the products.

Front

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts absorb light energy and convert it into chemical energy.

Front

What type of energy transformation occurs during photosynthesis?

Back

Light energy is transformed into chemical energy.

Front

How does the carbon cycle's impact on the food chain?

Back

Carbon cycles through the food chain, increasing and decreasing in amount.

Front

What is the relationship between carbon dioxide absorption and exhalation?

Back

The amount of carbon dioxide absorbed by one plant equals the amount exhaled by one human.
