define biotic limiting factors and give an example

Answer 1

Biotic limiting factors are components of an ecosystem that affect the abundance and distribution of organisms due to interactions with other living organisms. These factors can include competition, predation, parasitism, disease, and reproductive success.

An example of a biotic limiting factor is competition for resources. In a forest ecosystem, multiple tree species may compete for sunlight, water, and nutrients. The abundance and growth of each tree species can be limited by the presence and efficiency of other tree species in utilizing these resources. This competition can lead to the dominance of certain species that outcompete others, thereby limiting their abundance and distribution.
