Practice questions testing deep understanding of biological magnification, acid rain, and ozone depletion.
Q1. A nearby factory releases a very low, almost undetectable amount of toxic mercury into a lake. Years later, biologists test the top predatory birds (like eagles) living near the lake and find lethal concentrations of mercury in their bodies. Explain the biological concept that caused this massive buildup.
Q2. Assertion (A): The depletion of the ozone layer directly causes global warming. Reason (R): The hole in the ozone layer allows more heat from the sun to enter and get trapped in the atmosphere.
