Answer: C. There is energy to support life on earth.
The earth receives thermal energy from the sun via. radiation. This energy is captured by chlorophyll pigments of plants and other organisms to conduct photosynthesis. The sunlight energy is necessary for synthesis of food in the form of glucose. The glucose is converted into chemical form of energy as ATP which is required for respiration process in plants. Photosynthesis and respiration both are necessary processes to sustain life of plants, which further support life of other living organisms. Therefore, energy transfer support life on earth.
