Which of the following members of the food chain are most alike?

65% Answer Correctly

herbivores and autotrophs

scavengers and decomposers

primary consumers and omnivores

producers and tertiary consumers

Which of the following is not true of light waves?

62% Answer Correctly

can travel through a vacuum

are electromagnetic waves

are mechanical waves

travel faster than sound waves
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.

3
