I.
Population evolve to maximise their reproductive fitness, also called
Darwinian reproductive fitness (higher  value), in the habitat in which
they liveII. The
population growth rate is inversely related to generation
timeIII. The
housefly, which has a short life span and produces a large number of eggs,
could be considered as a K selected speciesIV. Under
a particular set of selection pressures, organisms evolve towards the most
efficient reproductive strategiesV. Life
history traits of organisms have evolved in relation to the constraints
imposed by biotic and abiotic factors in their habitatSelect

housefly which has a short life span and produces a large number of eggs
could be considered as r selected speciesDepend
upon the giving birth their are two type of speciesr
selected species organism
of this type give more young ones during their life cycle. Parent care their
children less and their size are also littleK
Selected Species Organisms
of this kind gives less birth during their life cycle. They care more their
children. Their size and life span are more than selected species,  man, mammal, bird, etc. |
