I Many secondary compounds are produced by plants for the purpose of discouraging herbivores (Grazers and Browsers).
II. Predators generally are high on lethality and low on intimacy
III. Predators in nature are prudent because they do not exploit their prey.
IV Parasites are low on lethality and high on intimacy

• A. Statements I and IV only
• B. Statements I and II only
• C. Statements I, 11 and III only
• D. All statements are correct

Answer 1

The correct option is D All statements are correct

1. Many secondary compounds like cardiac gkycosidrs are produced by plants like Calotropis to discourage herbivores.

2. Predators attack and feed on flesh directly instead acquiring nutrition directly from host making them high on lethality and low on intimacy.

3. Predators are prudent since they never feed on the entire population of prey preventing their exploitation.

4. Parasites acquire nutrition from host directly instead of attacking aninaks for flesh, hence are low on lethality and high on intimacy.

So, the correct option is 'All statements are correct'.
