☀ autotroph

Here's why:

• Autotrophs are organisms that can produce their own food using light, water, and carbon dioxide (or other chemicals) through a process like photosynthesis.

• Pseudotrophs and ambitrophs are not widely used scientific terms.

Since mango trees use photosynthesis to make their own food, they are classified as autotrophs.
