Answer

The first species to colonize the lawn that is allowed to undergo succession would possess “weedy” traits. The interaction between the species would be inhibiting or facilitating in nature. The site’s history would influence which species appear at each stage during and after the succession.

Work Step by Step

The revival that follows after the removal of entire or most of the species from an area (terrestrial or aquatic) is known as succession. The first species that will appear in succession should have good dispersal ability, rapid rate of reproduction, fast growth, and the ability to tolerate adverse and severe conditions. Thus, the two-acre lawn of college is more likely to be colonized with the species having “weedy” traits or characteristics, as these species have the ability to establish in the disturbed soil. Other than that species interactions and site history plays an important role.
