The nutrients received by heterotrophic part of the lichen from the autotrophic part are

The correct option is C Carbohydrates

• The algal component carries out photosynthesis and produces carbohydrate glucose during the dark reaction of photosynthesis.
• Minerals are provided to the algal part by fungal mycelium. It absorbs water and minerals from the substratum.
• Lipids and proteins are neither supplied by algal part nor fungal part but synthesized within the organism itself.
• So the correct answer is 'Carbohydrate'.
