Adaptive Features (Cambridge (CIE) IGCSE Biology)

Adaptations & Fitness

• Adaptive features are the inherited functional features of an organism that increase its fitness

• Fitness is the probability of an organism surviving and reproducing in the environment in which it is found

• You should be able to interpret images or other information about a species in order to describe its adaptive features, for example:

A typical question here might be to explain how the leaf area and distribution and density of stomata help different species of plant survive in their different habitats
