Niche

A niche is the functional role of an organism in its environment, including how it uses resources and interacts with other organisms.

• Niche is the functional role and position of a species in an ecosystem, including its food, shelter, and interactions with other organisms.
• Each species has a unique niche, and no two species can occupy the same niche, which helps reduce competition.
• Types of niche include spatial (habitat), trophic (food level), and multidimensional (interaction of many environmental factors).
• Fundamental niche is the potential role without competition, while realised niche is the actual role in the presence of competition.
• Niche is influenced by abiotic factors such as temperature, water, light, and soil.
