Question

chapter 3

1. photosynthesis produces sugars from

a) water, carbon dioxide, and energy.
b) water, other sugars, and oxygen.
c) oxygen, carbon dioxide, and water.
d) carbon dioxide, enzymes, and energy.
e) oxygen, water, and energy.

1. the process of photosynthesis and cellular respiration are similar in that they both

a) capture energy in the form of sugar.
b) occur in all living organisms.
c) temporarily store energy in chemical bonds.
d) capture energy from the sun.
e) none of these are correct.

1. the process of cellular respiration

a) helps primary producers store energy accumulated by chloroplasts.
b) releases energy from chemical bonds of molecules such as glucose.
c) eliminates the need for enzymes in metabolism.
d) does not occur in primary producers.
e) does not occur in detritivores.

1. all members of a species that live in the same area at the same time make up a(an)

a) species.
b) ecosystem.
c) community.
d) population.
e) biome.

1. a biological community consists of all

a) populations living and interacting in an area.
b) members of a species living in the same area.
c) living things on earth.
d) populations of a given species.
e) members of a species living in the same biome.

Explanation:

• Question 22: Photosynthesis uses water, carbon - dioxide and energy (from sunlight) to produce sugars.
• Question 23: Both photosynthesis and cellular respiration temporarily store energy in chemical bonds (ATP in cellular respiration and sugar in photosynthesis).
• Question 24: Cellular respiration releases energy from the chemical bonds of molecules like glucose.
• Question 25: A population is all members of a species that live in the same area at the same time.
• Question 26: A biological community consists of all populations living and interacting in an area.

Answer:

1. A. water, carbon dioxide, and energy.
2. C. temporarily store energy in chemical bonds.
3. B. releases energy from chemical bonds of molecules such as glucose.
4. D. population.
5. A. populations living and interacting in an area.
