Photorespiration can decrease soybeans’ photosynthetic output by about 50%. would you expect this figure to be higher or lower in wild relative of the soybeans. why?

This figure will be lower in wild relative of the soybeans

Explanation:

In farm produce, the genetic diversity is controlled due to which species of any plant/crop cannot undergo genetic mutation and hence its evolution gets halted.

While in case of wild crop/plants, genetic diversification continues at natural pace.

By this logic wild soyabeans shall certainly evolve after a certain period of time to curb the losses occurring due to photorespiration

Hence, this figure will be lower in wild relative of the soybeans

Explanation:

Natural selection is the mechanism that is responsible for the evolution of organisms.  

In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.  

The C. cantonensis is brighter in color whereas the C. multidentata is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore C. cantonensis is more susceptible. The mottled drab species is not easily predated by the species.  

The 30 % offsprings of C. cantonensis can survive till the reproductive age  whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.

The species with mottled drab color is the result of the differential reproductive rate.
