Question

which of the following is most likely a factor that could affect the rate of photosynthesis? surrounding animals carbon dioxide concentration soil type age of plant

Explanation:

Photosynthesis is the process by which plants use sunlight, carbon - dioxide, and water to produce glucose and oxygen. Carbon dioxide is one of the key reactants in the process. Higher carbon dioxide concentrations can generally increase the rate of photosynthesis up to a certain point. Surrounding animals usually do not directly affect the rate of photosynthesis. Soil type mainly affects nutrient and water availability rather than directly influencing the photosynthetic process. The age of the plant can have some impact on overall health and photosynthetic capacity, but carbon dioxide concentration is a more direct and significant factor for the rate of photosynthesis.

Answer:

carbon dioxide concentration
