The equation of exponential growth curve of population has 'r’ that mean which of the following statements?

1. Extrinsic rate of natural increase
2. An important parameter for assessing impacts of only biotic factors on population growth
3. For Norway rat, it's value is 0.15
4. For flour beetle it is 0.12

What does K mean?

1. Nature's Carrying Capacity
2. Number of individuals of a species supported by nature as per the resources available
3. A maximum possible number of individuals of a species under practical circumstances.
4. All of these

In V-PL growth curve, the asymptote is reached when

1. It's lag phase
2. Just before the lag phase
3. At the time of curve reaching to K
4. The time before deacceleration.

By a particular interaction in a population one species was harmed while other was benefited. Such interaction is called as

1. Competition
2. Predation
3. Parasitism
4. Both B and C

The interacting species live closely together in which of the following interaction?

1. Parasitism, Predation and Amensalism
2. Commensalism, Amensalism
3. Mutualism and Competition
4. Parasitism, Predation, Commensalism

Predation can be thought as

1. Prey's way to control it's population
2. Nature's way of transferring energy to higher trophic levels.
3. Nature's way of controlling predators food chain
4. Predator's way of controlling prey's energy level
