Question

this image shows lichens and mosses on a rock. which type of succession is taking place here? eutrophic primary tertiary

Explanation:

To determine the type of succession, we analyze each option:

• "Eutrophic" relates to nutrient - rich environments (e.g., in water bodies for eutrophication), not ecological succession on rocks.
• "Primary succession" occurs on newly formed or barren surfaces (like bare rock) where no soil initially exists. Lichens and mosses are pioneer species in primary succession as they can colonize bare rock and start soil formation.
• "Tertiary" is not a recognized type of ecological succession (the main types are primary and secondary).

Answer:

B. primary
