Q: If the solar constant is $$1370 \text{ joules}/(m^2$ \times sec)$$, and 46% of this strikes the surface of Earth, what is the approximate range of solar energy received at the surface?

$$600 - 650 \text{ joules}/(m^2$ \times sec)$$

Question 1

Which process in cells is primarily responsible for converting glucose and oxygen into ATP, water, and carbon dioxide?

Accepted Answer

Cellular respiration

Question 2

What is the main entry point for energy flow into most ecosystems on Earth?

Accepted Answer

Sunlight striking the planet

Question 3

Which equation best represents the overall process of photosynthesis?

Accepted Answer

$$6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6$ + 6O_2$$

Question 4

Which of the following best describes an ecological community?

Accepted Answer

A group of species living in the same area and able to interact with each other

Question 5

What is the solar constant, and what does it represent?

Accepted Answer

The average amount of solar radiation received by Earth's atmosphere per unit area

Question 6

If the solar constant is $$1370 	ext{ joules}/(m^2$ 	imes sec)$$, and 46% of this strikes the surface of Earth, what is the approximate range of solar energy received at the surface?

Accepted Answer

$$600 - 650 	ext{ joules}/(m^2$ 	imes sec)$$

Question 7

Which of the following is a consequence of Earth's tilted axis and its orbit around the sun?

Accepted Answer

Seasonal variation in sunlight and temperature

Question 8

What is the primary reason for the formation of alternating bands of wet and dry climate on Earth?

Accepted Answer

Air circulation cells

Question 9

Which of the following best describes the biosphere?

Accepted Answer

The sum of all the planet's ecosystems and landscapes

Question 10

How does the angle of incoming sunlight affect the amount of energy absorbed by a location on Earth?

Accepted Answer

A higher angle increases energy absorption

Question 11

Which of the following is NOT a direct result of sunlight striking Earth?

Accepted Answer

Plate tectonics

Question 12

What is the main difference between an ecosystem and an ecological community?

Accepted Answer

An ecosystem includes both communities of organisms and the physical factors they interact with, while a community is just the group of interacting species

Question 13

Which of the following best explains the lake-effect snow phenomenon?

Accepted Answer

Cold air passing over a warm lake picks up moisture, which then precipitates as snow downwind

Question 14

What is the effect of a rain shadow on local climate?

Accepted Answer

It creates dry conditions on the leeward side of a mountain

Question 15

Which of the following is a likely response of species distributions to climate change?

Accepted Answer

Species will shift poleward or to higher altitudes as temperatures rise

Question 16

Which process is responsible for the release of chemical waste such as carbon dioxide and water in organisms?

Accepted Answer

Catabolism

Question 17

What is the relationship between atmospheric CO$$_2$$ levels and infrared (IR) radiation absorption?

Accepted Answer

As CO$$_2$$ levels rise, more IR radiation is absorbed, warming the atmosphere

Question 18

Which of the following is a real-world example of how local climate can deviate from global climate patterns?

Accepted Answer

Lake-effect snow formation

Question 19

Which of the following is the correct sequence of energy flow from the sun to an organism?

Accepted Answer

Sunlight $$\rightarrow$$ Photosynthesis $$\rightarrow$$ Chemical energy $$\rightarrow$$ Cellular respiration $$\rightarrow$$ ATP
