Fungi are represented by which of the following examples?

Fungi are a diverse group of organisms that play essential roles in ecosystems, including decomposition and symbiotic relationships. The relationship highlighted in the correct choice involves lichens and mycorrhizae.

Lichens are a symbiotic association between fungi and photosynthetic organisms, typically algae or cyanobacteria. This partnership allows fungi to provide structure and protection while receiving nutrients produced by the photosynthetic partner. This unique adaptation enables lichens to thrive in various environments, including harsh conditions where neither organism could survive alone.

Mycorrhizae are another crucial representation of fungi, forming symbiotic relationships with plant roots. In this association, the fungal mycelium helps plants absorb water and minerals from the soil, which enhances nutrient uptake. In return, the plant supplies carbohydrates to the fungus, creating a mutually beneficial relationship that is vital for plant health and growth.

Both lichens and mycorrhizae illustrate the significance of fungi beyond simple spore-producing organisms, showcasing their integral roles in ecological interactions and nutrient cycles.
