This question has several parts that must be completed sequentially. if you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. the population of the world was about 5.3 billion in 1990. birth rates in the 1990s ranged from 35 to 40 million per year and death rates ranged from 15 to 20 million per year. let's assume that the carrying capacity for world population is 110 billion. (assume that the difference in birth and death rates is 20 million/year = 0.02 billion/year.) exercise (a)step 1 the year 2100 corresponds to t = 110 2110 step 2 rounding your answer to two decimal places, p(110) 7.88 x billion you cannot come back) exercise (d) what are your predictions if the carrying capacity is 65 billion?
