The role of the mountain lion in this ecosystem is an example of the concept that

• ecosystems require a large number of predators to increase the number of prey

• populations are linked with many others in a stable ecosystem

• large animals waste food, resulting in harm to other organisms in the ecosystem

• predators should consume small prey to protect the diversity of the ecosystem

• are random events that always increase the ability of members to reproduce

• occur only in sexually reproducing organisms

• may result in gene variations that provide a survival advantage

The best-adapted individuals in a population are most likely to be successful in passing on their traits to the next generation because

• they were able to survive the conditions of their environment when others could not

• their offspring will be better able to cope with any environmental changes that may occur

• their genes are the strongest, which will help them attract suitable mates

• they are less attractive and are less likely to find suitable mates

8 Scientists found that over a period of 300 years, a pond slowly transformed into a meadow and then a forest. During that time, communities of organisms were replaced by different communities. The best explanation for why new communities were able to replace the older communities is that ...

• the species in the old communities died of disease

• the environment gradually changed, making the area less favorable for the old communities

• there was a lack of predators for the new communities of organisms

• the original species suddenly became extinct
