Question

both plants and animals take in carbon from the environment. during photosynthesis, plants take in carbon dioxide (co₂) from the air. they use co₂ and energy from the sun to make glucose. plants use glucose as food and as a building block for all of their cells. when an animal eats a plant, carbon in the plant becomes part of the animal’s body.

select the true sentences.

• coyotes take in carbon from the environment when they eat other animals.
• co₂ is absorbed by squirrels during photosynthesis.
• plants use glucose as a building block for their cells.
• plants use co₂ and energy from the sun to make glucose.

Explanation:

• Coyotes take in carbon from the environment when they eat other animals: As per the text, when an animal eats a plant (or in this case, when a coyote eats another animal which has carbon from plants), carbon becomes part of the animal's (coyote's) body.
• CO₂ is absorbed by squirrels during photosynthesis: Squirrels are animals and do not perform photosynthesis. Only plants perform photosynthesis.
• Plants use glucose as a building block for their cells: The text states “They (plants) use CO₂ and energy from the Sun to make glucose. Plants use glucose as food and as a building block for all of their cells”.
• Plants use CO₂ and energy from the Sun to make glucose: The text clearly says “During photosynthesis, plants take in carbon dioxide (CO₂) from the air. They use CO₂ and energy from the Sun to make glucose”.

Answer:

Coyotes take in carbon from the environment when they eat other animals.
Plants use glucose as a building block for their cells.
Plants use CO₂ and energy from the Sun to make glucose.
