How can an organism have two niches?

An organism can have two niches by exhibiting different roles or functions in separate environments or contexts. For example, a species might thrive in both aquatic and terrestrial habitats, adapting its behavior, feeding strategies, or reproductive methods accordingly. Additionally, an organism may occupy one niche during one life stage and another niche in a different stage, such as a frog that lives in water as a tadpole and on land as an adult. This flexibility allows for resource utilization and survival in varying conditions.
