Photosynthesis is the process by which a plant transforms solar energy into chemical energy. Which of the following correctly describes the roles of each of the materials involved in photosynthesis?

Sunlight is captured by chlorophyll, combines with carbon dioxide and water molecules, and creates glucose molecules. Any remaining atoms form oxygen and water molecules that are released as waste products.

Jeremy was asked to describe the impact of humans on the carbon cycle. He answered: “When people drive cars they add more carbon dioxide to the atmosphere.” Jeremy only received partial credit for his answer. Which of the following answers could have received full credit?

Humans add carbon dioxide to the atmosphere when they undergo cellular respiration, burn fuel in cars and factories and burn biomass. Humans take in carbon from the food they eat. They return carbon to the soil through waste products and decomposition

Humans add carbon dioxide to the atmosphere when they burn fuel in cars and factories, and through respiration. Humans take in carbon from the food they eat and when they breathe in carbon dioxide. They return carbon to the soil through garbage decomposition.

Humans add carbon dioxide to the atmosphere when they burn fuel in factories and other biomass sources. Humans take in carbon dioxide through respiration. They return carbon to the soil through biomass decomposition.

Humans add carbon dioxide to the atmosphere when they burn fuel and other biomass sources. Humans take in carbon from the food they eat and from the soil and return it back to the soil through waste products and decomposition.

What are the reactants of photosynthesis?

Sunlight, carbon dioxide, and water

Which of the following best explains the relationship between photosynthesis and cellular respiration?

Cellular respiration uses the glucose produced by photosynthesis to make energy.

Photosynthesis produces the energy necessary for performing cellular respiration.

Photosynthesis produces the light energy necessary for performing cellular respiration.

Cellular respiration uses the glucose produced by photosynthesis to make glucose as a source of food.

Sarah believes that only animals undergo cellular respiration. Drew believes that both plants and animals undergo cellular respiration. Only one student is correct. Which answer choice best explains why?

Drew is correct because both plants and animal cells need chemical energy to carry out cellular processes.

Sarah is correct because plant cells do not need chemical energy for cellular processes and animal cells do.

Drew is correct because plants need to store more chemical energy for consumers and animals need chemical energy for cellular processes.

Sarah is correct because plant cells already have chemical energy stored in them and animal cells need chemical energy for cellular processes.

Which of the following best describes the carbon cycle?

The continuous movement of carbon among the atmosphere, oceans, soil, and living organisms.

The process by which carbon is converted into oxygen and released into the atmosphere.

The transformation of carbon into nitrogen through photosynthesis.

The conversion of carbon into fossil fuels over millions of years.

How is carbon transferred from animals to the atmosphere?

Through respiration, where animals exhale carbon dioxide.

Through the process of photosynthesis.

By the decomposition of dead organisms.

By the absorption of carbon dioxide from the atmosphere.

How do oceans contribute to the carbon cycle?

By absorbing carbon dioxide from the atmosphere.

By storing carbon in the form of fossil fuels.

By releasing carbon dioxide through volcanic activity.

By converting carbon dioxide into oxygen.

What happens to carbon in the bodies of dead organisms?

It is broken down by decomposers and returned to the soil.

It is immediately released into the atmosphere as carbon dioxide.

It is converted into oxygen through photosynthesis.

It remains unchanged and is stored indefinitely.
