Question

Refer to the figure below. Two communities are represented by each rank abundance curve of species abundances within each community. Which of the following is true? A. The relative abundance for common species is more similar than for rarer species between the two communities. B. The community with more species has relatively higher evenness (hint: look at distribution of relative abundances) among species. C. The community with less species has relatively higher evenness (hint: look at distribution of relative abundances) among species. D. Both A and B In the tidal zone of a rocky coastline, the greatest diversity is observed in the because of A. high tidal zone, intermediate tidal disturbance, keystone species regulation B. intertidal zone, high tidal disturbance, keystone species regulation C. low tidal zone, intermediate tidal disturbance, keystone species regulation D. intertidis zone, intermediate tidal disturbance, keystone species regulation E. intertidal, intermediate tidal disturbance. low competrtiol, F. benthic zone, low tidal disturbance, low competition

Explanation / Answer

D) Both A and B. Relative abundances of the most common species with ranks 1 to 6 are more closer between the two communities. D) Inter-tidal zone, intermediate tidal disturbance, keystone species regulation. The keystone sprcies is the starfish which, keeps the control on the population of the invasive species by predating on them. D) Species 2 outcompetes, but both have equal carrying capacity. Both of them are influencing each other.
