Why are lupine important to primary succession?

Nitrogen-fixing plants, such as lupines (Lupinus sp.), are critical to primary succession, as these species enrich the otherwise intolerable soil and allow other species to subsequently establish [2].

Explanation:

. ph changes the ability of them he enzyme to dissolve in water.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
