Question

carbon enters the biosphere from the atmosphere or hydrosphere when autotrophs - organisms, like plants and algae, that make their own food - perform photosynthesis to make the carbohydrate glucose (c₆h₁₂o₆). the process of photosynthesis is represented by this chemical equation. 6co₂ (g) + 6h₂o (l) → c₆h₁₂o₆ (aq) + 6o₂ (g) carbon dioxide water glucose oxygen select the true statements. glucose is a product of photosynthesis. carbon dioxide gas is released during photosynthesis. photosynthesis requires light energy. autotrophs need oxygen and water to perform photosynthesis.

Explanation:

1. In the photosynthesis equation $6CO_2(g)+6H_2O(l)\xrightarrow{light}C_6H_{12}O_6(aq) + 6O_2(g)$, glucose ($C_6H_{12}O_6$) is on the product - side, so it is a product of photosynthesis.
2. Carbon dioxide ($CO_2$) is a reactant, not a product released during photosynthesis.
3. The symbol $\xrightarrow{light}$ above the arrow indicates that light energy is required for photosynthesis.
4. Autotrophs need carbon - dioxide and water to perform photosynthesis, oxygen is a product.

Answer:

A. Glucose is a product of photosynthesis.
C. Photosynthesis requires light energy.
