Question

A population has a current size of 100 and time steps are measured in years. If λ = 1.2, how big will the population be after 4 years? A.)1076 B.)159 C.) 207 D.) 312

A species of cleaner fish removes parasites from another species of fish that is much bigger in size. The big fish keeps cleaner fish predators away. This type of species interaction is classified as: A.) Mutualism B.) Competition C.) Neutralism D.) Antagonism

It is estimated that a flock of wood buffalo cranes should be able to sustain an r of 0.085 for the foreseeable future. If the flock currently contains 350 individuals, how long will it take for that population to double? A.) between 7 and 9 years B.) between 9 and 11 years C.) between 11 to 13 D.) Less than 7 years

A population has a current size of 100 and time steps are measured in years. If λ = 1.2, how big will the population be after 4 years? A.)1076 B.)159 C.) 207 D.) 312

Ans. C

Explanation

A species of cleaner fish removes parasites from another species of fish that is much bigger in size. The big fish keeps cleaner fish predators away. This type of species interaction is classified as: A.) Mutualism B.) Competition C.) Neutralism D.) Antagonism

Ans. A

Explanation: This is a clear case of the mutual benefit of both the big and small fish where each of the participants has get the advantage of the presence of others. Competiton and antagonism certainly do not have such association and affect the individual organism negatively. Neutralism do not have any effect on the participating organisms.
