Final answer:
Interference competition describes the direct conflict between two bird species over berries, and it could lead to extinction or greater specialization over time for the less adapted species B.
Step-by-step explanation:
The type of competition between two species of birds that actively fight over berries, resulting in injuries and limiting survival and reproduction of one species by the presence of the other, is known as. Interference competition is a direct form of competition where organisms actively prevent each other from accessing resources, often through aggressive interactions.
Over time, some possible outcomes of this interspecific competition on species B could include extinction if species B is less well adapted to securing the limited resource, or species B might evolve greater specialization to utilize different resources or strategies for survival. This evolutionary change is known as character displacement.
In summary, interference competition can have significant impacts on the population dynamics and evolutionary trajectories of the species involved, leading to potential specialization or extinction.
