The biological association that contributes directly to succession in a community is
Answer Details
Succession is the process of gradual change in the species composition of a community over time. It can be primary, which occurs in a newly formed habitat without any pre-existing organisms, or secondary, which occurs in a disturbed habitat where some organisms already exist.
One of the main biological associations that contribute directly to succession in a community is competition. Competition occurs when two or more organisms require the same resources such as food, water, light, or space. As the community develops, the competition for resources becomes more intense, leading to the dominance of certain species over others.
This dominance results in changes in the community structure and composition, as some species become more successful at obtaining resources than others. This can lead to a shift in the dominant species as the community develops, a process known as ecological succession.
Predation, parasitism, and commensalism are not direct contributors to succession. Although they can affect the distribution and abundance of species in a community, they do not directly influence the order in which different species replace each other during succession.
Therefore, the correct answer is option A - competition.
