Answer

Brief Explanations:

Lichens are pioneer species. They secrete acids that break down rocks. This process of weathering rock gradually forms soil. Soil is essential for the establishment of other plant species as it provides a medium for root anchorage and nutrient uptake. The other options are incorrect: lichens do not reflect sunlight to help other plants grow (they photosynthesize for their own needs but not in a way that reflects light for others in this context), they do not directly provide energy for other plants (unlike how producers in a food chain might in a different sense), they are not a significant food source for pollinators in the context of facilitating plant establishment, and they clearly do help (by forming soil) so the "do not help" option is wrong.

Answer:

They break down rock and form soil.
