A heterotroph is an organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter. All animals, non-photosynthetic plants, fungi, and many bacteria are heterotrophs.

Looking at the given options:

1. Macroscopic multicellular algae: These are autotrophs, not heterotrophs. They perform photosynthesis to produce their own food.

2. Methanogens: These are a type of archaea that produce methane. They are not heterotrophs; they are chemotrophs, getting their energy from chemical reactions.

3. Methanotrophs: These are bacteria that use methane as their carbon source. They are not heterotrophs; they are chemotrophs.

4. Free-living unicellular algae: These are autotrophs, not heterotrophs. They perform photosynthesis to produce their own food.

5. The algae that are symbiotic inside lichens: These are autotrophs, not heterotrophs. They perform photosynthesis to provide food for both themselves and their fungal partners.

None of the options provided are examples of heterotrophs.
