Read the Statements given below and answer the question(s) that follow:
The nutrients enable living organisms to build their bodies, to grow, to repair damaged parts of their bodies and provide the energy to carry out life processes. Nutrition is the mode of taking food by an organism and its utilisation by the body. The mode of nutrition in which organisms make food themselves from simple substances is called autotrophic nutrition. Therefore, plants are called autotrophs. Animals and most other organisms take in food prepared by plants. They are called heterotrophs.
The leaves of green plants have a green pigment called chlorophyll. It helps leaves to capture the energy of the sunlight. This energy is used to synthesise food from carbon dioxide and water. Since the synthesis of food occurs in the presence of sunlight, it is called photosynthesis. So, we find that chlorophyll, sunlight, carbon dioxide and water are necessary to carry out the process of photosynthesis. It is a unique process on the earth. The solar energy is captured by the leaves and stored in the plant in the form of food. Thus, sun is the ultimate source of energy for all living organisms.
“Sun is the ultimate source of energy for all living organisms” because:

“Sun is the ultimate source of energy for all living organisms” because:
The correct option is D Plants get the energy to produce food from the sun, that is consumed by animals
Plants need solar energy to perform photosynthesis by which they prepare food.
Plants need solar energy to perform photosynthesis by which they prepare food.
