Answer :
Answer:
Change in food source.
Explanation:
If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.
Natural selection can contribute to variations in gene frequency throughout time as a result of changes in food supply.
Changes in gene frequency:
If the organism's food supply changes, it will have to adjust to the new situation.
For example, Darwin's Theory on the Galapagos Islands' finches. There were several distinct types, ranging in size and beak shape. This happened due to changes in food supplies, and they evolved in order to access more of them.
