The type of organism that obtains energy by metabolizing molecules produced by other organisms is called a heterotroph.

Here's why:

* Heterotroph: This term literally means "other feeder". Heterotrophs cannot produce their own food (like plants do through photosynthesis). Instead, they must consume other organisms or organic matter to get the energy they need.

Examples of heterotrophs include:

* Animals: They eat plants or other animals.

* Fungi: They decompose dead organisms.

* Bacteria: Many bacteria break down organic matter or consume other organisms.
