Are humans autotrophs or heterotrophs ?explain why

Humans are heterotrophs.

Here is why:

Heterotrophs are organisms that cannot make their own food. Although us humans can cook, we can not take energy from the sun and make it into glucose, making energy for ourselves.

On the other hand, autotrophs are algae, plants, and even some bacteria. All of these examples can make their own food. They use the process of photosynthesis to take energy from the sun, along with carbon dioxide from the air and water from the soil around it to produce glucose. This glucose is used as their energy, which they make independently.
