Answer 2

The algal component in the association does photosynthesis to produce food and the fungi collects water and minerals for absorption.

Explanation:

• The symbiotic relationship between algae and fungi is called as Lichens.
• The algal component which generally consists of green algae or blue green algae has the photosynthetic pigment and does the process of photosynthesis which provides food for both of these components.
• The fungal element present in the association helps the algae to survive in harsh climatic conditions because of their filamentous structure, and makes water and useful minerals available to the algae for absorption and making of food.
• Lichens can survive in harsh conditions and also acts as natural pollution indicators because they do not grow in areas having high sulphur dioxide levels.
