Explanation:

The student should make a model of a local food web describing the importance of solar energy for the life on earth. This is because of the fact that solar energy is the basic source of energy for a food web. A food chain is a linear sequence of transfer of food and energy when one organism is consumed by another organism. A food web is a interconnection of two or more food chains. The food chain at the initial level includes producers which includes all photosynthesizing organisms like plants which captures the light energy from sun to produce their food. The plants are consumed by many organisms on earth. Therefore, food web model will demonstrate the role and importance of sun for existence of life on earth.
