62% Answer Correctly

	atmosphere
	lithosphere
	geosphere
	hydrosphere

In the heart, the __________ artery and vein manage blood flow to the lungs.

69% Answer Correctly

	atrial
	aorta
	pulmonary

The coldest point in the Earth's atmosphere is reached in which atmospheric layer?

52% Answer Correctly

	mesosphere
	stratosphere
	thermosphere
	troposphere

Solution

In the mesosphere, temperature again drops as altitude increases until the coldest point in the Earth's atmosphere, the mesopause, is reached where temperatures fall to −225 °F (−143 °C).

Examples of tertiary consumers include:

73% Answer Correctly

	chickens
	fish
	cows
