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. Generally, loss of biodiversity should be regarded seriously, not only because the organismsthat 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) toextinction in the future. 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 comparedwith food webs in real ecosystems, but they still illustrate a key difference between more diverseand less diverse ecosystems.
