Question

Give reason for the following? Sun is the ultimate source of energy for all living organisms

Answer 1

Answer:

The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.

Answer 2

Answer:

The plants prepare the food using solar energy through the photosynthesis process, so it is the ultimate source of energy.

Explanation:

• The leaves of plants capture the solar energy and store this energy in the form of food.
• Solar energy can be termed renewable energy.

The process of photosynthesis in plants is not possible without solar energy. Solar energy is used by plants in the process of photosynthesis to give oxygen gas and energy (sugar).

This energy gets stored in plants in the form of food. The organisms at the various levels utilize this stored food in the plants to get energy.

So, without solar energy, plants would not be able to make food as photosynthesis would not be possible. Higher-level organisms would not be able to survive without food.

Hence, for all living organisms, the ultimate source of energy is solar energy.
