Learn About the Difference Between Habitat and Niche
In ecology, organisms interact with their environment in different ways. Two important concepts that define an organism’s relationship with its surroundings are habitat and niche. These terms are often confused but have distinct meanings.
Understanding the difference between habitat and niche helps in studying biodiversity and the survival strategies of different species.
What is Habitat?
A habitat is the natural environment or place where an organism lives. It provides the necessary resources such as food, water, shelter, and space for survival. A habitat can be as large as a forest or as small as a drop of water.
Types of Habitat:
Terrestrial Habitat – Found on land (e.g., forests, grasslands, deserts)
Aquatic Habitat – Found in water (e.g., oceans, rivers, lakes)
Aerial Habitat – Organisms that spend most of their time in the air (e.g., birds, bats)
What is Niche?
A niche is the functional role of an organism in its ecosystem. It includes how the organism interacts with other species, how it obtains food, and how it contributes to the ecosystem’s balance.
Types of Niche:
Fundamental Niche – The potential role an organism can occupy without competition
Realised Niche – The actual role it occupies when competition exists

FAQs on Habitat Vs Niche: Definition, Key Differences and Examples
1. What is the major difference between habitat and niche?
A habitat is the physical place where an organism lives, while a niche is its role and interactions within that environment.
2. Can two species share the same habitat and niche?
Two species can share the same habitat, but they cannot share the same niche due to competition.
3. Why is a niche important in an ecosystem?
A niche determines an organism’s role in maintaining ecological balance, such as controlling populations and contributing to nutrient cycles.
4. How does a habitat change over time?
Habitats can change due to climate change, deforestation, pollution, and natural disasters.
5. What happens if two species try to occupy the same niche?
This leads to competition, and one species will either adapt, relocate, or face extinction (Competitive Exclusion Principle).
6. Can a species change its niche?
Yes, due to environmental changes or competition, some species adapt and modify their niche to survive.
7. How do humans impact habitats and niches?
Human activities like urbanisation, pollution, and deforestation destroy habitats and disrupt species’ niches.
8. What is an example of a broad niche and a narrow niche?
Broad Niche: Raccoons eat a variety of foods and adapt to different environments.
Narrow Niche: Koalas feed only on eucalyptus leaves, limiting their adaptability.
9. Why do predators and prey have different niches?
Predators help control prey populations, while prey serve as food sources, maintaining a balanced food chain.
10. What is a real-world example of habitat and niche?
Habitat: Coral reefs are home to many marine species.
Niche: Clownfish live in sea anemones, gaining protection while helping the anemone stay clean.
