(2019·天津高考·阅读理解C篇)[1]How does an ecosystem
(生态系统)work What makes the populations of different
species the way they are Why are there so many flies and so
few
wolves To find
an
answer,
scientists have built
mathematical models of food webs,noting who eats whom and
how much each one eats.
[2With such models,scientists have found out some key
principles operating in food webs.Most food webs,for instance,
consist of many weak links rather than a few strong ones.When a
predator(掠食动物)always eats huge numbers of a single prey
(猎物)，the two species are strongly linked;when a predator lives
on various species,they are weakly linked.Food webs may be
dominated by many weak links because that arrangement is more
stable over the long term.If a predator can eat several species,it
can survive the extinction (of one of them.And if a predator
can move on to another species that is easier to find when a prey
species becomes rare,the switch allows the original prey to
recover.The weak links may thus keep species from driving one
another to extinction.(共66张PPT)
