If the larvae of a particular species of mosquito are to survive to the adult stage, the eggs must be laid in the trapped pool of water of the northern pitcher plant. The mosquito larvae provide no apparent benefit or harm to the pitcher plant. This type of interaction is an example of
commensalism
mutualism
parasitism
competition

Scientists found, that over a period of 200 years, a mountain pond was transformed into a meadow. During that time, several communities of organisms were replaced by different communities. What is this process called?
limiting factors
climax community
pioneer organism
ecological succession
Predator population lags behind prey population because......
Increase in predators leads to decrease in prey
Increase in predators leads to increase in prey
Increase in predators leads to decrease in producers
Increase in producers leads to increase in prey
