Question

Species that are the first colonizers of a habitat undergoing primary succession:

1) evolve into secondary succession specialists over time
2) alter their habitat so it becomes more favorable to other species
3) are usually the most efficient competitors for resources
4) help maintain their habitat to inhibit colonization by other organisms

Answer 1

Pioneer species in primary succession alter their habitat to be more favorable for subsequent species, contributing to soil formation and ecological transformation.

Step-by-step explanation:

Species that are the first colonizers of a habitat undergoing primary succession are known as pioneer species. These species, such as bacteria and lichens, are able to colonize environments devoid of soil and initiate the ecological transformation. Your answer to the question is that pioneer species alter their habitat so it becomes more favorable to other species. Through their life activities, they contribute to soil formation, making it more conducive for subsequent plant growth. As these organisms grow and die, they add organic material to the environment, leading to improved soil quality, allowing grasses, shrubs, and ultimately trees to grow. The area gradually transitions to a state of equilibrium with a new community of organisms that are different from the pioneer species.
