Final answer:
Heterotrophs are organisms that obtain energy by consuming other organisms. Examples include humans, dogs, and fungi.
Step-by-step explanation:
An organism is classified as a heterotroph if it cannot produce its own food and relies on consuming other organisms for nutrition. Heterotrophs obtain energy by breaking down organic matter. Examples of heterotrophs include:
- Humans: We consume plants and animals to obtain energy.
- Dogs: They rely on eating dog food or other animal products for nutrition.
- Fungi: Fungi obtain nutrients through the decomposition of organic matter.
