    What is a pioneer community in biology?

    A:

    In biology, the variety of plants, animals and fungi that first colonize a barren habitat is known as a pioneer community. These organisms are the first in the order of biological succession for that habitat and are followed first by seral communities and then by climax communities. Generally, some drastic change to the habitat occurs, destroying the previous biological community, before the pioneer community organisms enter.

  • Q:

    What are analogous structures?

    A:

    Analogous structures are similar features of different animals that have evolved due to convergent evolution. When two different species live in similar environments, they often evolve in a similar way. This causes the bodies of the two different species to develop similar structures even though they may have started with very different bodies.
