A population of Paramoecium caudatum was grown in a culture medium. After $5$ days the culture medium became overcrowed with Paramoeium and had depleted nutrients. What will happen to the population and what type of growth curve will the population attain ? Draw the growth curve.

In a population, unrestricted reproductive capacity is called

$I.$ Population evolve to maximise their reproductive fitness, also called Darwinian reproductive fitness (higher $r$ value), in the habitat in which they live

$II.$ The population growth rate $r$ is inversely related to generation time

$III.$ The housefly, which has a short life span and produces a large number of eggs, could be considered as a ' $K$ ' selected species

$IV.$ Under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategies

$V.$ Life history traits of organisms have evolved in relation to the constraints imposed by biotic and abiotic factors in their habitat Select the combination of correct statements

With the help of suitable diagram describe the logistic population growth curve.

Carrying capacity is

The population of an insect species shows an explosive increase in numbers during rainy season followed by its disappearance at the end of the season. What does this show ?
