Question

2) A group of scientists is studying two populations of elephants. The first population was hunted to near extinction because of the value of their tusks until new laws were passed within the last year making elephant hunting illegal. The population remains small. The second population lives in an area that is relatively undisturbed by humans with abundant natural resources. Though many other plant and animal species live in the area, the elephants are under no threat from human disturbance. Which of the two populations is more likely to exhibit exponential population growth over the next 10 generations? Which is more likely to exhibit logistic population growth? Explain the rationale for your answer. 3) Marine biologists tagged and released 50 marlin. Later, fishermen caught 300 marlin, 15 of which had tags. What is the estimate for the number of marlin in the population? 2) A group of scientists is studying two populations of elephants.

Explanation / Answer

The first population will grow exponential because their number will be much below than the carrying capacity so they will grow exponential upto the time they reached their carrying capacity.

The Secend population will not grow exponantial because they are in a place where they are undisturbed by humans with abundant natural resources. That means there number will be abundant and will be close to their carrying capacity.

  dN/dt = r N (1 - N/K)

Growth rate slows as population approaches carrying capacity.

3) Approximately 5 percent of the population is tagged means tagged one are 5 percent of total population

so if the tagged marlin number is 50 then the total main number will be 1000 (20 times more than the tagged one)
