multiple choice questions: choose the correct answer from the choices for each question.

1. what process do plants use to take in carbon dioxide and produce oxygen?

a. respiration
b. photosynthesis
c. evaporation
d. condensation

1. which human activity increases the amount of carbon dioxide in the atmosphere?

a. planting trees
b. burning fossil fuels
c. drinking water

Explanation:

1. When forests are cut down, carbon - stored in trees is released into the air as carbon dioxide. This is because trees store carbon during photosynthesis, and deforestation disrupts this storage.
2. Photosynthesis is the process by which plants take in carbon dioxide and release oxygen. Respiration is the opposite (taking in oxygen and releasing carbon dioxide), evaporation is related to water changing to vapor, and condensation is water vapor changing back to liquid.
3. Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere. Planting trees helps reduce carbon dioxide as they absorb it during photosynthesis, and drinking water has no direct impact on atmospheric carbon dioxide levels.

Answer:

1. carbon dioxide
2. B. Photosynthesis
3. B. Burning fossil fuels
