Question

What type of association is shown by lichens (an alga and fungus), in which the fungal component absorbs water and nutrients for both organisms, while the algal component manufacturers food for both organisms through photosynthesis?

• A. Parasitism
• B. Commensalism
• C. Predation
• D. Mutualism
• E. Interspecific competition

Answer 1

The correct option is D Mutualism

Lichens are a small group of plant-like organisms, whose body is made up of algal and fungal components. Both algal and fungal partners are benefited from the association in which the fungal component absorbs water and nutrients for both the organisms, while the algal component manufactures food for both organisms through photosynthesis. Such a type of relationship is known as mutualism or symbiotic relationship.

So, the correct answer is option D.
