which of the following is not a function of the crowns of forest trees during the daytime?

Options

A. absorb sun's light energy
B. absorb oxygen from air
C. carry out photosynthesis
D. form a green cover

Answer

To determine which of the following is not a function of the crowns of forest trees during the daytime, we need to analyze each option provided:

1. **Absorbs Sunlight Energy**: This is a function of the crowns of trees. The crowns, or canopies, of trees absorb sunlight for photosynthesis, which is essential for the trees to produce food.

2. **Absorb Oxygen from Air**: This option is incorrect as a function of tree crowns. Trees primarily absorb carbon dioxide from the air and release oxygen during photosynthesis. Therefore, absorbing oxygen is not a function of the crowns.

3. **Carry out photosynthesis**: This is indeed a function of the crowns. The crowns of trees are involved in photosynthesis, where they use sunlight to convert carbon dioxide and water into glucose and oxygen.

4. **Form a green cover**: This is also a function of the crowns. The crowns of trees provide a green cover that helps in maintaining the ecosystem and provides habitat for various organisms.

Based on this analysis, the option that is **not a function of the crowns of forest trees during the daytime** is:

**Answer: Absorb Oxygen from Air.**
