65% Answer Correctly

	producers
	carrion
	simple nutrients
	complex carbohydrates

The rate of vibration of sound is called:

82% Answer Correctly

	amplitude
	volume
	frequency
	period

Solution

The rate of vibration of sound is called frequency and is measured in hertz (Hz). One hertz is one repetition per second and sounds with high frequency have a higher pitch than sounds with lower frequency. Humans can hear sounds in the range of 20 Hz to 20 kHz.

Examples of secondary consumers include:

52% Answer Correctly

	plankton
	chickens
	grasshoppers
	wolves

Solution

Secondary consumers that also eat producers are known as:

62% Answer Correctly

	carnivores
	herbivores
	scavengers
	omnivores

Solution

Secondary consumers (carnivores) subsist mainly on primary consumers. Omnivores are secondary consumers that also eat producers. Examples are rats, fish, and chickens.
