In the process of ecological succession, what role do lichens and mosses typically play?

They are secondary consumers that feed on herbivores.
B
They are apex predators that control the population of herbivores.

They are primary producers that establish the initial soil layer.
Verified step by step guidance1
Understand the concept of ecological succession, which is the process by which the structure of a biological community evolves over time.
Recognize that lichens and mosses are often pioneer species in ecological succession. Pioneer species are the first organisms to colonize a barren environment.
Identify the role of lichens and mosses as primary producers. They can photosynthesize, meaning they convert sunlight into energy, and do not rely on other organisms for food.
Acknowledge that lichens and mosses contribute to soil formation. They break down rocks into smaller particles, creating the initial soil layer necessary for other plants to grow.
Conclude that lichens and mosses are not consumers or predators, but rather primary producers that play a crucial role in establishing the initial conditions for further ecological development.
