Survivorship Curves

Q. What is survivorship curve and how is it useful?

1. It is a plot of the age of organism against number of survivors in each age
2. The curve explains how many of the newborn will survive in each organism
3. It gives an idea if the organism follows K or R strategy of growth
4. It indicates the organism's ability to survive natural disasters

Q. Survivorship curve gives an accurate idea of an organism’s growth rate and growth rate strategy.

1. True
2. False

Q. Which of the following Population is most likely to go extinct
