B4.2.12—Fundamental vs. realized niche Topic Practice
Practise comparing potential and actual niches, using competition, distribution loss and habitat evidence to explain niche limits.
How this is tested
- distinguish a fundamental niche as potential conditions from a realised niche as actual use
- compare niches by linking competition to reduced access to habitat or food resources
- suggest how removing competition could let a species occupy a wider range of conditions
