2.1) — Solve. 21) An endangered species of fish has a population that is decreasing exponentially (A-Agekt). The population 6 years ago was 1600. Today, only 900 of the fish are alive. Once the population drops below 100, the situation will be irreversible. When will this happen, according to the model? (Round to the nearest whole year.) A) 23 years from today B) 22 years from today C) 25 years from today D) 24 years from...

Number of aphids present per day
EXERCISE 1 Understanding Population Growth with optimal conditions (eg, unrestricted resources and low competition), some populations grow in a predicable pattern. Early growth is relatively slow, after which growth is rapid. This rapid, logarithmic phase of growth represents the organism's blotic potential, which is its maximal reproductive capacity if given unlimited resources, exponential growth. N=(a)(2) Where: N = the number of individuals of a given generation. a = the number of individuals present initially....
