Question

which two products of photosynthesis do animals rely on? oxygen and sunlight water and oxygen sugar and oxygen carbon dioxide and sugar

Explanation:

1. Recall the photosynthesis equation: Plants use carbon dioxide and water (with sunlight energy) to produce glucose (sugar) and oxygen.
2. Analyze each option:

• "Oxygen and sunlight": Sunlight is an input, not a product animals rely on as a substance.
• "Water and oxygen": Water is an input for photosynthesis, not a main product animals rely on (animals get water from other sources too, but the question is about photosynthesis products).
• "Sugar and oxygen": Sugar (glucose) is a source of chemical energy, and oxygen is needed for respiration. Both are products of photosynthesis that animals rely on.
• "Carbon dioxide and sugar": Carbon dioxide is an input for photosynthesis, not a product animals rely on.

Answer:

C. Sugar and oxygen
