Final answer:
Sunlight provides energy for photosynthesis, which is a process where plants convert carbon dioxide and water into glucose and oxygen, storing the sun's energy as chemical potential energy. This is essential for plant survival and growth, and supports life on earth. Therefore, the correct answer is b) Sunlight provides energy for photosynthesis.
Step-by-step explanation:
The transfer of energy from the sun helps plants through the crucial process of photosynthesis. During photosynthesis, plants absorb solar energy from the sun and use this energy to convert carbon dioxide and water into glucose and oxygen.
This conversion stores the sun's energy as chemical potential energy within the glucose molecules. Therefore, the correct answer to the question is b) Sunlight provides energy for photosynthesis.
Sunlight is vital for plants because it is the energy source that drives the synthesis of food in the form of sugars, which not only contributes to the growth of plants but also supports life on earth by producing oxygen and serving as the base of the food chain.
If plants did not have access to sunlight, they would not be able to perform photosynthesis, leading to a lack of energy and eventually their demise, which would affect all organisms relying on them.
