Predators play important role in
| 1. | Conduction of energy across trophic levels |
| 2. | Maintainance of species diversity |
| 3. | Control of prey population |
| 4. | More than one option is correct |
Camouflage is an important mechanism where
| 1. | Predators are never cryptically coloured for easy capturing of their prey |
| 2. | Prey species are cryptically coloured to avoid being detected easily by the predator |
| 3. | Prey produces some poisonous chemicals in their surroundings to protect themselves from predators |
| 4. | Predators evolved some physiological adaptations to reach to the prey present in some harsh habitats |
Which is the correct order of ecological hierarchy?
| 1. | Biome Populations Community Organism |
| 2. | Organism Biome Population Community |
| 3. | Population Community Biome Organism |
| 4. | Organism Population Community Biome |
Predators are different from parasites as
| 1. | They feeds on living host |
| 2. | They have poor means of dispersal |
| 3. | They have high biotic potential |
| 4. | They help to maintain species diversity |
Select incorrect statement regarding different population attributes
| 1. | Natural selection operates at population level |
| 2. | Size of the population tells a lot about its status in the habitat |
| 3. | In age pyramids age distribution of male and females are shown in separates diagrams |
| 4. | Population is a group of individuals multiplying by sexual and asexual reproduction |
When does the growth rate of a population following the logistic model equal zero? The logistic model is given as dN/dt = rN(1 - N/K)
| 1. | when death rate is greater than birth rate |
| 2. | When N/K is exactly one |
| 3. | When N nears the carrying capacity of the habitat |
| 4. | When N/K equals zero |
