Biology P Homework 3.4

The steps of the carbon cycle are described below. Place the steps in the correct order.

a.) animals and plants release carbon dioxide and water as a result of cellular respiration

b.) carbon dioxide is released by plants and animals and moves into the biosphere.

c.) plants use water and carbon dioxide from the atmosphere to make sugar and oxygen through the process of photosynthesis

d.) animals and plants use sugar and oxygen for the process of cellular respiration

e.) cellular respiration transforms sugar and oxygen into carbon dioxide and water.

Which statement describes a difference between the nitrogen and carbon cycles?

• The carbon cycle involves only plants.

• The nitrogen cycle requires a process called fixation, which makes the nitrogen more usable for living organisms.

• The carbon cycle requires that temperatures be above 27 °C (80 °F).

• The nitrogen cycle occurs entirely in the ocean.

What are the potential effects of introducing too much nitrogen and phosphorus into an aquatic ecosystem? Select all correct answers.

• Fish populations would increase.

• Aquatic organisms would die off.

• Water would become clearer.

• Algae would grow out of control.

• Oxygen levels would increase.
