Question

Which of the following is the correct statement?

Options

• heterotrophs synthesise their own food

• heterotrophs utilize solar energy for photosynthesis

• heterotrophs do not synthesise their own food

• heterotrophs are capable of converting carbon dioxide and water into carbohydrates

Answer 1

heterotrophs do not synthesise their own food.

Explanation:

Heterotrophs (such as animals, fungi, and most bacteria) are organisms that lack chlorophyll. Because they cannot trap solar energy, they are completely incapable of manufacturing their own organic food from simple inorganic raw materials like carbon dioxide and water. Instead, they must obtain their nutrition by consuming or absorbing energy from other living or dead organisms (autotrophs or other heterotrophs).
