A broad niche refers to an organism that:

A broad niche indicates that an organism is adaptable and versatile in its habitat. This means that it has the ability to thrive in various environments and can consume a wide range of food sources. Such flexibility allows the organism to exploit different resources available in its ecosystem, which can be essential for survival, especially in changing conditions or when certain resources become scarce. For example, animals with broad niches can relocate to different areas or adjust their diet based on what is accessible, enhancing their chances of survival in diverse situations. This adaptability is crucial in dynamic ecosystems where competition for resources is prevalent.

In contrast, options that imply specialization, such as having a specific role in a habitat or only surviving on a single type of food, reflect narrow niches. Organisms classified with narrow niches are usually more vulnerable to environmental changes since they depend on particular conditions or resources. Therefore, a broad niche is characterized by the ability to live in multiple climates and consume various foods, exemplifying resilience and adaptability in biological diversity.
