Question

photosynthesis provides over ____ percent of the energy for life on earth.
a 100
b 75
c 50
d 99

Explanation:

Photosynthesis is the primary process by which energy enters the biosphere. It converts light - energy into chemical - energy that is used by plants and other photosynthetic organisms. Most of the energy for life on Earth ultimately comes from the sun, and photosynthesis is the main way this solar energy is captured. Over 99% of the energy for life on Earth is provided by photosynthesis either directly (in the case of photosynthetic organisms) or indirectly (when non - photosynthetic organisms consume photosynthetic organisms or their products).

Answer:

d. 99
