Answer 2

Dear Student.,

SOLUTIONS:

1. Yes, its true that all life on earth is bottled sun's energy or sun is the ultimate source of energy on earth. We known that all living beings are directly or indirectly dependent on plants for food. These plants prepare their own food in the presence of sunlight. So, if there is no sun, no photosynthesis leading to the death of all plants. Consequently, the entire food web will get disturbed. In the absence of plants herbivores will decrease in number, herbivores are the source of food for canivores so indirectly every organism will suffer due to absence of sunlight. 


2. Because the stomach doesn't absorb nutrients. Villi of the small intestine are small finger-like projections on the surface. One villus contains many cells and thereby increase the surface area (see image below). This is required because a lot of nutrients have to be absorbed in the small intestine. Lots of cells on a small area makes this process efficient.

The stomach collects the food, adds gastric acid and enzymes for digestion of food. The stomach does not absorb any nutrients and therefore does not require a larger surface area.

3. When we do vigorous exercise we don't receive enough oxygen as per body need and  lactic acid formation takes place in muscles  This lactic acid is responsible for the pain in muscles.
