The biological association that contributes directly to succession in a community is

Explanation

The question is asking which biological association directly contributes to succession in a community. In simple terms, succession refers to how an ecosystem changes over time. The options given are competition, predation, parasitism, and commensalism. Competition is when two or more organisms compete for the same resources, such as food or territory. This can lead to the survival of the most adapted organism, but it does not directly contribute to succession. Predation is when one organism feeds on another organism. While it can have an impact on the size and distribution of populations, it also does not directly contribute to succession. Parasitism is a relationship in which one organism benefits at the expense of the other organism. While it can have an impact on the health of populations, it also does not directly contribute to succession. Commensalism is a relationship in which one organism benefits without affecting the other organism. This also does not directly contribute to succession. Therefore, the correct answer is option A, competition, as it can lead to the survival of the most adapted organism, which can then contribute to the succession of the ecosystem. It is important to note that succession is a complex process that involves multiple factors, including abiotic and biotic factors, and can take a long time to occur.
