Which of the following statements are correct ? (i) When resources in the habitat are limited then the population grows in an exponential or geometric fashion. (ii) Intrinsic rate of natural increase is a very important parameter chosen for assessing impacts of any biotic or abiotic factor on population growth. (iii) Intrinsic rate of natural increase in 1981 for human population in India was 0.0205. (iv) A population growing in a habitat with unlimited resources show sigmoid curve and this type of population growth is called Verhulst-Pearl Logistic Growth. (v) Since resources for growth for most animal populations are finite and become limiting sooner or later, the exponential growth model is considered a more realistic one. (vi) Populations evolve to maximise their reproductive fitness, also called Darwinian fitness (high r value), in the habitat in which they live. (vii) Some organisms like pacific salmon fish, bamboo breed only once in their lifetime.
