Who was right? Many ecologists have made precise measurements, designed to test the assumptions of both the Clements and Gleason models. For instance, along mountain slopes, does one life zone, or habitat type, grade sharply or gradually into another? If the divisions are sharp, perhaps the reason is that the community is so well integrated, so holistic, so like Clements viewed it, that whole clusters of species must remain together. If the divisions are gradual, perhaps, as Gleason suggested, each species is responding individually to its environment, and clusters of species are not so integrated that they must always occur together.
What did the ecologists in paragraph 4 hope to determine with their measurements?
选项
A、Whether different species compete for the same environments
B、Whether habitats are sharply separated or gradually flow into each other
C、Whether succession differs in different types of habitats
D、Whether integrated communities survive better than independent communities
答案
B
