Explanation:

Analyze the relationship between algae and fungi in lichens

Using the Evolutionary Adaptation knowledge point, we analyze the interaction described. The text states that algae undergo photosynthesis to provide food for the fungi, while the fungi provide anchorage and protection for the algae. Because both organisms benefit from this close physical association, they share a mutualistic relationship.

Identify the nature of disease-causing fungi

Using the Pathogens and Pathogen Definition knowledge points

$$ \text{Disease-causing organisms} \equiv \text{Pathogens} $$

Since some fungi cause diseases in humans, these disease-causing fungi are classified as pathogens.
