Question

A species of grasshopper lives for only one year, but reproduces multiple times in its breeding season. It is a small, short-lived species that grows quickly and reaches sexual maturity early, and produces many, small offspring. Based on this information, which of the following statements is CORRECT? Select ALL correct answers.

A.	This grasshopper is probably r-selected, or close to r-selected on the spectrum of population growth

B.	This grasshopper is iteroparous because it reproduces more than once in its lifetime

C.	This grasshopper is semelparous because it completes its entire life cycle in one year

D.	This grasshopper is semelparous because it invests heavily into each reproductive bout, which we can see in the many offspring it produces

Answer 1

Q) A species of grasshopper lives for only one year, but reproduces multiple times in its breeding season. It is a small, short-lived species that grows quickly and reaches sexual maturity early, and produces many, small offspring. Based on this information, which of the following statements is CORRECT? Select ALL correct answers.

Answer- A,B

A- This grasshopper is probably r-selected, or close to r-selected on the spectrum of population growth.

B- This grasshopper is iteroparous because it reproduces more than once in its lifetime.

Explanation- It is considered under r-selection or close to r-selection, in the population growth curve because in case of r-selection, small size of the organism is considered, grasshopper is small in size, it produces many offsprings, it shows short life time, and in this early maturity occurs, all these are characteristics of r-selection.

Here the grasshopper lives for one year, but reproduces many times. so it is considered Iteroparous , because in this mode of reproduction organism shows multiple reproductive cycle in lifetime, and here grasshopper reproduces more than once.
