Question 5

Farmers sprayed rice paddies in Taiwan to suppress populations of a small rice mite.This also killed the populations of a predatory mite that controlled the numbers of rice mites.Soon the spraying did no good,and the damage to the rice from the rice mite was greater than before spraying had occurred.Few predatory mites existed in the paddies now.This happened because both mites were K-selected and resistance was a matter of chance.

Question 17

In tidal pools,the food pyramid is "inverted." There is a small base of phytoplankton and a larger top of zooplankton.

Accepted Answer

A) This proves that sometimes it is possible for a small amount of plant tissue to produce a large amount of herbivores. 
B) This is based on numbers,and there are a few large algae plants feeding many very small animals. 
C) These plants are actually deriving their food from dying animals,thus the pyramid is inverted. 
D) The pyramid appears inverted because it is based on a very short time sample,over a year the algae production would likely be ten times the zooplankton in biomass or energy.
