Which is an effect of lower levels of solar radiation striking Earth?

Answer:
B) decreased rates of photosynthesis
Explanation:
Plants, phytoplankton, algae, and other microorganisms photosynthesize using energy in the form of solar radiation. Photosynthesis is a chemical process that's integral to these organisms, which are called producers.
They combine light energy from solar water and carbon dioxide, in a complex process that produces chemical energy in the form of glucose.

Photosynthesis is a rate-limited reaction; it depends on various factors including carbon dioxide availability and light intensity. When light is limited, the rate of photosynthesis decreases due to its slowing effect on the light-dependent reaction in photosynthesis, occurring in the chlorophyll.
