Birth rate (natality) calculation
-
If there are 250 snails in a pond, and within a year their number increases to 2500 by reproduction. What should be their birth rate per snail per year?Increase in population $=2500-250=2250$. Birth rate per capita $=\dfrac{2250}{250}=9$ per snail per year.
That is every question in Organisms and Populations for this filter.
