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 animals body. image of carbon cycle with tree, squirrel, wolf, and co₂ arrows for photosynthesis, respiration, food consumption, death and decomposition, decomposition select the true sentences. animals use co₂ and energy from the sun to make glucose. after eating a nut, carbon from the nut becomes part of a squirrels body. co₂ is absorbed by trees during photosynthesis. plants use glucose as food.

Explanation:

1. For "Animals use \( \text{CO}_2 \) and energy from the Sun to make glucose": From the text, only plants use \( \text{CO}_2 \) and solar energy for photosynthesis (making glucose), animals do not. So this is false.
2. For "After eating a nut, carbon from the nut becomes part of a squirrel's body": The text says "When an animal eats a plant, carbon in the plant becomes part of the animal’s body". A nut is part of a plant, so this is true.
3. For "\( \text{CO}_2 \) is absorbed by trees during photosynthesis": The text states "During photosynthesis, plants take in carbon dioxide (\( \text{CO}_2 \)) from the air", and trees are plants, so this is true.
4. For "Plants use glucose as food": The text says "Plants use glucose as food and as a building block for all of their cells", so this is true.

Answer:

The true sentences are:

• After eating a nut, carbon from the nut becomes part of a squirrel's body.
• \( \text{CO}_2 \) is absorbed by trees during photosynthesis.
• Plants use glucose as food.
