Based on how they obtain their nutrition, living organisms has been classified to be either producers, consumers, or decomposers. Producers are organisms capable of synthesizing their own food using light (photosynthesis) or inorganic chemicals (chemosynthesis).

Consumers, on the other hand, cannot synthesize their own food and hence, rely on other organisms to obtain their energy source. Consumers feed on other organisms to obtain energy. In this question, a fruit fly is classified as a CONSUMER because it cannot synthesize its own food.

Eating potatoes with the skin as opposed to without the skin can increase dietary fiber intake. A medium-size baked potato weigh
KATRIN_1 [288]

Answer:

  • <em><u>There are 1.6g more of fiber in the the potato with skin than the potato with flesh only</u></em>

<em><u /></em>

Explanation:

In the internet, you can find that a regular potato (medium-sized) with the skin contains about 4 grams of fiber; and half that is  in the skin , thus a potato without skin contains about 2 grams of fiber.

In other site, I found that the source used to deal with this question states 4.2 grams of fiber for <em>White, Flesh and Skin (173 grams)</em> and <em>2.6 grams for Potatoes, Baked, Flesh Only (173 grams)</em>.

Therefore, using the second reference, the differnce in the amount of fiber, in grams,  for the potato with skin and the potato with flesh only is:

  • 4.2g - 2.6g = 1.6g

The answer is that there are 1.6g more of fiber in the the potato with skin than the potato with flesh only.
