Which of the following contributes an increase in population density?

Under a particular set of selection pressure, organisms evolve towards the most ...$A$... reproductive strategy. Some organisms breed only ...$B$... in lifetime while others breed ....$C$... in life time

Choose the correct option for $A, B$ and $C$

Population termed $r$ - strategists

Give differences: Natality rate and Mortality rate

When environmental conditions are favourable, then population growth curve will be

$I.$ 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
