Give an exampke of a biotic limiting factor in a forest ecosystem?

An example of a limiting factor is the amount of sunlight in a rainforest. The growth of plants on the forest floor is limited by light availability. The limiting factor also accounts for competition between individual organisms.

Explanation:

The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks and water. But abiotic factors can be intangible, such as temperature, other types of radiation and the chemistry of soil and water.
