讀到 ecology，想起了【石頭記】，「自創」了兩條題目，大家看看我有沒有潛質做石 sir 的助教。
Q1. Why taking high salt content meals frequently is harmful? (2M)
according to someone, all compounds containing chlorine atoms are harmful (like DDT) 1
table salt contains chlorine atom (NaCl) 1
Q2. With reference to the food chain of zooplankton, minnows, needlefish and ospreys, explain why DDT is specially harmful to ospreys? (4M)
ospreys feed on a large number of needlefish 1
needlefish feeds on a large number of minnows 1
minnows feed on a large number of zooplanktons 1
zooplanktons absorb a large amount of DDT in water 1
so ospreys have the largest amount of DDT in individual
