A) Maximum mortality and minimum natality
B) Mortality minimum
C) Natality minimum
D) Mortality maximum
Correct Answer: A
Solution :
Maximum reproductive capacity or biotic potential (r) can be realised only when environment resources are non-limiting and conditions favour minimum mortality (specific mortality). However environment has limiting effect on the rise of population. The sum of abiotic (eg. Temperature, water space etc.) and biotic (eg. Food, competition, disease, predation etc.) factors checks the rese in population size and prevents the species to realise its biotic potential. It helps in limiting population size to below the carrying capacity.
