Solution:Joseph Grinnell referred to the "ecological or environmental niche" as the ultimate distributional unit of "species and subspecies". An ecological niche refers to a species' specific role or position within its ecosystem.It includes the conditions created by both living (biotic) and non-living (abiotic) elements of the ecosystem that affect the species' ability to reproduce and obtain essential resources like food, water, and shelter. Additionally, a niche encompasses the impact the species has on its ecosystem.
An ecological niche is the role and position of a species in its environment, describing how it interacts with resources and competitors and how it affects these factors. It includes how a species grows when resources are abundant and threats are minimal and how it competes for resources, serves as prey, and hunts for food.
A species' niche depends on biotic factors like food and predators and abiotic factors such as temperature, soil nutrients, and light. For example, dung beetles eat dung and store it for their larvae, which helps recycle nutrients and aerate the soil.
