View the step-by-step solution to:


A biologist conducted an experiment on two islands (A and B) of similar size, climate, species composition, and

richness. Originally, the same species of snake was present on both islands. In her experiment, the biologist removed the species of snake from island A but NOT from island B. She then recorded the number of animal species on each island over a period of 24 months. The data collected is shown in the graph below:


 A line graph shows the number of species present on two islands (A and B) over a period of 24 months. The number of species on island A decreased steadily from 36 species down to 10 species by month 16, and then remained around 10 species from months  

Analyze the data above in terms of interspecific relationships and communities and propose an explanation for the difference in species present on each island over the course of the experiment.

The interspecific competition is low in case of island B and is high in case of island A as the... View the full answer
