Assertion : Species with low genetic variability are more vulnerable to disease, predators or other environmental challenges.

Assertion :Species with low genetic variability are generally at greater risk of extinction than the species with more genetic variability. Reason: Species with low genetic variability are more vulnerable to disease, predators or other environmental challenges.

Assertion :Species with low genetic variability are generally at greater risk of extinction than the species with more genetic variability. Reason: Species with low genetic variability are more vulnerable to disease, predators or other environmental challenges.

Assertion: Species is a genetically closed system. Reason: Because the reproductive isolation constitutes the most important boundary between different species.

Assertion: Species is a genetically closed system. Reason: Because the reproductive isolation constitutes the most important boundary between different species.

Assertion : Predators maintain species diversity. Reason : Predators reduce the intensity of competition among competing prey species.

Assertion : Predators maintain species diversity. Reason : Predators reduce the intensity of competition among competing prey species.

Assertion : Predatos maintain species diversity. Reason : Predators reduce the intensity of competition among competing prey species.

Assertion: Prey species have evolved various defences to lessen the impact of predation. Reason: Some species of insects and frogs are cryptically-coloured (camouflageed) to avoid being detected easily by the predator
