Question

The food we eat provides the building blocks (e.g. amino acids and simple sugars) for making organic molecules and provides the energy for generating ATP. Humans would therefore be classified as:

A) Heterotrophs

B) Photoautotrophs

C) Chemoautotrophs

D) Photoheterotrophs

Now, I know it's not B) nor D) because humans do not use light to obtain energy, it's either A) or C) but which one?

Answer 1

Heterotrophes because we get our food from plants and animals and break it down. thereby, we cannot be chemoautotrophes because we donot secrete chemicals to produce food and we don't produce our own food. this is a good question. we get food from others and we make our energy.

Answer 2

A Heterotrophs - We live live off the energy of other organisms. We cannot make our own energy (like photoautotrops or chemoautotrophs). Chemoautotrophs are organisms that survive off the inorganic chemicals like methane or sulfur compounds in very inhospitable areas of the Earth.

Answer 3

Almost all heterotrophs, INCLUCING HUMANS, are completely dependent on photoautotrophs for food and also for oxygen, a by product of photosynthesis.

Your answer is A

Answer 4

Well, the "auto" in Chemoautotroph suggests that humans make food for themselves (contrary to your premises). The "hetero" in heterotroph suggests we get our food from something "different". So I believe it's 'A'

Answer 5

A... Chemoautotrophs would mean that we'd convert ourselves into chemicals to feed ourselves (which DOES happen during malnutrition) but really it's A

Answer 6

I would say heterotrophs. An organism that depends on complex organic substances for nutrition

Answer 7

that's not the ions that reason fluid loss, that's how they impact the physique. The ions avert water from getting previous them, for this reason struggling with appropriate absorption. The physique then eliminates the unabsorbed water via diarrhea. The fluid loss could be deadly, distinctly in youthful babies. the only thank you to get fluids to be absorbed by using the physique are by using ingesting issues like fluids with sugars or salts (water won't artwork because of the ions blocking off the absorption receptors in the gut).

Answer 8

most accurately, humans would be chemoheterotrophs, but that is not an option, so it's A

Answer 9

i would say A. her\terotrophs

Answer 10

c is the answer
