Infer Light intensity in the Sonoran Desert averages about 400 umol photons/mº/s. According to the graph, what would be the approximate rate of photosynthesis for
plants that grow in this environment? What other factors would affect a plant's
survival?

Light, temperature, water, humidity, and nutrition.

Explanation:

the higher rate of photosynthesis for  plants occurs that grow in the desert environment if other factors such as water, nutrients etc are also available for plants. Due to high intensity, the plants produces more food and as a result the growth of the plant increases. If water is not available for desert plants, the photosynthesis is slower down if the intensity of light is higher. Light, temperature, water, humidity, and nutrition are the factors that affect the survival of plants.
