Question

When continuity of distribution of a species is broken by uninhabited areas is known as

• A. Speciation
• B. Discontinuous distribution
• C. Punctured equilibrium
• D. Migration

Answer 1

The correct option is B Discontinuous distribution

• Animals are not uniformly distributed on land and in freshwater. They are restricted to certain places by several factors such as climate, food, shelter, flora and fauna etc.
• A distribution in which populations of related organisms are found in different places of the world without any traces between them is called discontinuous distribution. For example, lung flukes in Australia, Africa and South America shows discontinuous distribution.
• So, the correct answer is 'Discontinuous distribution'.
