Question

1. name four environmental factors that affect the rate of photosynthesis. (use commas to separate your responses)

temperature
amount of water
amount of sunlight (light intensity)
amount of carbon dioxide
amount of oxygen
amount of plants

Explanation:

To determine the environmental factors affecting photosynthesis, we recall that photosynthesis depends on light (for energy), carbon dioxide (reactant), water (reactant), and temperature (affects enzyme activity). Oxygen and number of plants are not direct environmental factors for the rate (oxygen is a product, and number of plants is not an environmental factor but a biological component). So the four factors are temperature, amount of water, amount of sunlight (light intensity), and amount of carbon dioxide.

Answer:

temperature, amount of water, amount of sunlight (light intensity), amount of carbon dioxide
