4

Which of the following is not true of light waves?

62% Answer Correctly

are electromagnetic waves

travel faster than sound waves

are mechanical waves

can travel through a vacuum


Solution

Unlike mechanical sound waves that require a physical medium for propagation, light waves are electromagnetic and can travel through empty space. Light waves are also much faster, travelling at 186,000 m/s vs. 343 m/s for sound waves.


5

Scavengers break down the dead bodies of plants and animals into which of the following?

65% Answer Correctly

producers

simple nutrients

carrion

complex carbohydrates


Solution

Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
