Question

Which one of the following is an example of mutualism?

Options

• Lichens

• Hypertrophy

• Cuscuta

• Nepenthes

Answer 1

Lichens

Explanation:

Lichens are a classic example of mutualism, a symbiotic relationship where both species involved benefit. In lichens, the algal component synthesizes organic food through photosynthesis, which feeds both itself and the fungal component, while the fungal partner provides water, minerals, and protection to the algae. This symbiotic mutualism benefits both partners, making lichens a well-known example of mutualism in nature.
