Explanation:
No a single consumer is a single consumer,
You can only be you, Although each has their own thoughts and opinions
Energy will take the path from sun to stomach as sun's energy to chemical energy followed by thermal and mechanical energy.
Explanation:
The energy of the sun is in the from of chemical energy which is the ultimate basis of life on earth . The process of photosynthesis occurs to form a chemical compound named glucose. The food ingested is in polymer complex forms as protein, carbohydrate, fats etc which is broken into monomers for absorption in intestine and stomach.
The dietary compound has energy stored in their bonds as chemical energy.
So, from sun human consume chemical energy which is stored in food.
The energy even if consumed by eating meat is also chemical energy which is stored as potential energy.
The breakdown of food or chemical energy into monomers leads to release of thermal energy or heat to maintain optimum body temperature.
Chemical energy also gets converted to mechanical energy which allows functioning of vital organs and movement of body.
Groundwater is enclosed in aquifers. Groundwater
is found within a large range of rocks, but the most effective aquifers
are found in porous, open cavities, and permeable rocks. Aquifers can
contain salty, briny, and fresh water. Groundwater can exit the aquifer
by the pumping of a well, which is usually called discharge. The answer is aquifers.
