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.
<h3><u>Answer;</u></h3>
D) frequently, and sometimes rapidly
<h3><u>Explanation;</u></h3>
- The hypothesis that the Grants have been testing was about the natural selection shaping the beaks of different bird populations.
- <em><u>The Grants documented that natural selection takes place in the wild finch population frequently, and sometimes rapidly.
</u></em>
- The Grants' work showed that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
The sun is the ultimate source
Evolution would least likely be a cause of natural selection.
Natural selection has to do with the survival of the fittest. Therefore, adaptation, variation, and overpopulation all have an impact on natural selection - those who do not adapt to their new surroundings due to overpopulation or those whose bodies have not modified enough will not survive.
