Directions: Read the paragraph and answer the question. Sunlight was changed into living plant tissue through the process of photosynthesis. Animals utilized these plants in their living activities and thus became another source of stored solar energy. As these plants and animals died, their stored solar energy was sometimes protected from decay by the action of fossilization. In other words, the remains of millions of plants and animals were trapped in large deposits beneath the earth's surface. Main idea: Sources of solar energy are stored. 4 Select the correct answer. Main idea: Sources of solar energy are stored. Which of the following details supports the main idea? A. Process of decay protects plant and animal sources of solar energy. B. Process of fossilization protects plant and animal sources of solar energy. C. Process of photosynthesis protects plant and animal sources of solar energy. D. Process of erosion protects plant and animal sources of solar energy.
