Research by James Byers on the relationship between a native and an invasive species of mud snail
A) demonstrated that the invasive species Batillaria grows faster than the native species Cerithidea.
B) demonstrated that at high densities Batillaria continued to grow at a relatively high rate while Cerithidea lost weight.
C) indicated that Batillaria is much more efficient at converting available food into its own biomass.
D) predicts a time to competitive exclusion of Cerithidea by Batillaria of 55 to 70 years.
E) All of the choices are correct.

Quizplus · Accepted Answer

All of the choices are correct. Byers' research showed that the invasive species Batillaria outcompeted the native species Cerithidea in terms of growth rate, biomass conversion efficiency, and ability to maintain growth at high densities. Furthermore, his modeling predicted that Cerithidea would eventually be competitively excluded by Batillaria within 55 to 70 years.
