Explanation:

First Question (about energy transfer in photosynthesis/cellular respiration)

To determine the correct statement about energy transfer:

• Photosynthesis converts light energy (sun) to chemical energy in glucose. Cellular respiration transfers chemical energy in glucose to ATP (or other uses).
• The option "Light energy from the sun is transferred into chemical energy in sugars (glucose)" describes photosynthesis correctly. The other options have errors: converting glucose to light energy (reverse of photosynthesis), incorrect conversion of glucose to CO₂ (respiration is more than just that), or incorrect energy transfer direction.

Light - independent reactions (Calvin cycle) of photosynthesis require carbon dioxide.

• Oxygen is a product of photosynthesis (light - dependent reactions produce it).
• Sunlight is needed for light - dependent reactions.
• Water is used in light - dependent reactions (for photolysis). Carbon dioxide is fixed in the Calvin cycle to make glucose.

An autotroph is an organism that makes its own food (using photosynthesis or chemosynthesis).

• Decomposers break down dead matter.
• Consumers eat other organisms.
• Protists are a diverse group (some are autotrophs, some heterotrophs, but the term for self - feeding is autotroph; since the options given might have a typo, but if we assume the intended correct option related to self - feeding, and if "autotroph" was missing, but among the given, there might be a mistake. However, if we consider the standard term, the correct term is autotroph. But since the options provided don't have autotroph, there might be an error. But if we re - evaluate, maybe a typo and the intended correct option related to producers (autotrophs). If we assume a possible correction, but based on the given options, there is an error. But if we consider the closest, maybe a mistake in the options. However, the standard term for an organism that makes its own food is autotroph (producer).

Answer:

The correct option is: Light energy from the sun is transferred into chemical energy in sugars (glucose).
