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

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.

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.
