Question

which statement explains how plants are dependent upon animals for their survival?
animals supply oxygen for plants to undergo aerobic respiration.
animals produce carbon dioxide for plants to use during photosynthesis.
animals provide chemical energy needed by plants for cellular respiration.
animals make lactic acid that plants use in photosynthesis.

Explanation:

Plants use carbon - dioxide for photosynthesis, which is produced by animals during respiration. Animals do not supply oxygen for plants (plants produce oxygen via photosynthesis), do not provide chemical energy for plants' cellular respiration, and lactic acid is not used by plants in photosynthesis.

Answer:

Animals produce carbon dioxide for plants to use during photosynthesis.
