In ecology, a niche (CanE, UK/ˈniːʃ/ or US/ˈnɪtʃ/) is a term with a variety of meanings related to the behavior of a species living under specific environmental conditions. The ecological niche describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another [and] the relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts".
The notion of ecological niche is central to ecological biogeography, which focuses on spatial patterns of ecological communities. "Species distributions and their dynamics over time result from properties of the species, environmental variation..., and interactions between the two — in particular the abilities of some species, especially our own, to modify their environments and alter the range dynamics of many other species." Alteration of an ecological niche by its inhabitants is the topic of niche construction.
To survive, each organism must establish their own niche and avoid niche overlap. Competition amongst species presents a struggle for survival. The best chance that a species has to survive is to avoid competition while successfully obtaining resources.
An organism's niche includes how and where they obtain resources for survival. An organism's niche also includes what they contribute to the ecosystem! For example, beavers obtain sticks and logs to build dams for their home. But, the dam impacts the flow of the river and the other organisms that live in the ecosystem. Bacteria are decomposers that break down dead organisms. But, they also return minerals to the soil which supports plants! These roles in the ecosystem are part of the organism's niche as well.

Niche Partitioning and Species Coexistence | HHMI BioInteractive video
Professor Robert Pringle describes the cutting-edge method of DNA metabarcoding used to reveal how similar animals share resources.
One of the big questions in ecology is how do similar animals coexist in the same place. Dr. Robert Pringle and his team are using new technologies to better understand the ways in which three different species of African antelope partition niches within their habitat.

An overview of what an ecological niche is, and the differences between fundamental and realized niches.

Introduction Habitat and Niche
Learn how the habitat and niche are different but also very important for a healthy environment.
A habitat is an ecological area where a plant or animal lives. It may be an island, a tree, or maybe under a rock. The habitat is where an individual can find food, shelter, protection and mates.
A niche is a role or position that an individual has in its environment. A niche may also involve what the individual eats, how it interacts with other living things, and also how it interacts with the nonliving factors. Without ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

Community Ecology: Feel the Love - Crash Course Ecology #4
Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous, so a lot of interactions are actually about side-stepping direct competition and instead finding ways to divvy up resources to let species get along.

"Unlocking Humpback Whale Secrets: Dr. Mithriel MacKay on Whale Behavior, Culture, & Conservation | Teach Me to Dive"
YouTube Description: Dive deep into the fascinating world of humpback whales with Dr. Mithriel MacKay, Marine Mammal Behavioral Ecologist and Director of Research at the Marine and Coastal Ecology Research Center. In this exclusive interview with Teach Me to Dive, Dr. MacKay shares groundbreaking insights from her long-term studies on North Atlantic humpbacks, discussing everything from whale social structures and cultural transmission to conservation challenges and whale-watching impacts.
Key topics include:
Significant behavioral changes in humpback whales
How social structures influence whale interactions
Cultural transmission of songs and feeding techniques
The biggest conservation threats facing whales today
The future of whale research and marine conservation
Have you ever wondered why humpbacks are arriving earlier to the Hawaiian Islands? Or how researchers count these magnificent creatures? Dr. MacKay answers viewer questions and reveals what excites her most about the future of marine mammal science.
Don't miss this deep dive into the lives of one of the ocean's most iconic species! 🌊🐋

This video defines fundamental and realized niches as they apply to community ecology, and looks into the interaction between different species of barnacles to illustrate both types of niches. The information in this video is found in chapter 54 of Campbell Biology 11th Edition.
In ecology, a niche (CanE, UK/ˈniːʃ/ or US/ˈnɪtʃ/) is a term with a variety of meanings related to the behavior of a species living under specific environmental conditions. The ecological niche describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another [and] the relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts".
The notion of ecological niche is central to ecological biogeography, which focuses on spatial patterns of ecological communities. "Species distributions and their dynamics over time result from properties of the species, environmental variation..., and interactions between the two — in particular the abilities of some species, especially our own, to modify their environments and alter the range dynamics of many other species." Alteration of an ecological niche by its inhabitants is the topic of niche construction.
