Read the following newspaper article and answer the questions which follow.
BIODIVERSITY IS THE KEY TO MANAGING ENVIRONMENT
An ecosystem that retains a high biodiversity (that is, a wide variety of living things) is much more likely to adapt to human-caused environment change than is one that has little.
Consider the two food webs shown in the diagram. The arrows point from the organism that gets eaten to the one that eats it. These food webs are highly simplified compared with food webs in real ecosystems, but they still illustrate a key difference between more diverse and less diverse ecosystems.
Food web B represents a situation with very low biodiversity, where at some levels the food path involves only a single type of organism. Food web A represents a more diverse ecosystem with, as a result, many more alternative feeding pathways. Generally, loss of biodiversity should be regarded seriously, not only because
the organisms that have become extinct represent a big loss for both ethical and
utilitarian (useful benefit) reasons, but also because the organisms that remain have
become more vulnerable (exposed) to extinction in the future.


Question 2: BIODIVERSITY
Food webs A and B are in different locations. Imagine if Leaf Hoppers died out in
both locations. Which one of these is the best prediction and explanation for the
effect this would have on the food webs?
A The effect would be greater in food web A because the Parasitic Wasp has only
one food source in web A.
B The effect would be greater in food web A because the Parasitic Wasp has
several food sources in web A.
C The effect would be greater in food web B because the Parasitic Wasp has only
one food source in web B.
D The effect would be greater in food web B because the Parasitic Wasp has
several food sources in web B.
