After reading the paragraphs below, answer the questions that follow.

Biosphere II is a huge, dome-covered, self-contained structure located outside Tucson, Arizona. It was built to try to duplicate Earth's biosphere and ecosystems in miniature and to use the information gained from this experiment to help design similar habitats on the Moon and Mars. Biosphere II contained small versions of many of Earth's ecosystems, including an ocean with a coral reef, mangrove wetlands, a grassland, a desert, an agricultural system, and a house for humans. Eight men and women were sealed inside the habitat for a proposed 2-year stay. The air, water, and food for these "biospherians" all came from inside the sealed habitat, and their only contact with the outside world was through computers and telephones.

Before the 2 years were up, however, the experiment failed. Supplemental oxygen was pumped into the facility, and food supplies were provided through the airlocks. What caused the failure of the experiment? It was traced to nutrient pollution. The soil in some of the biosphere ecosystems was unusually rich in nutrients. These excess nutrients caused a huge population explosion in decomposer bacteria, which led to oxygen depletion.


To stabilize the environment in the habitat and enable it to become self-sufficient again, it would be helpful to add
◦ producers to absorb excess carbon dioxide and produce oxygen.
◦ nitrates and phosphates to the terrestrial and aquatic ecosystems.
◦ decomposers to recycle nutrients in the soil and water.
◦ consumers to absorb carbon dioxide and produce oxygen.

Did you know?

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Vampire bats have a natural anticoagulant in their saliva that permits continuous bleeding after they painlessly open a wound with their incisors. This capillary blood does not cause any significant blood loss to their victims.

Asthma attacks and symptoms usually get started by specific triggers (such as viruses, allergies, gases, and air particles). You should talk to your doctor about these triggers and find ways to avoid or get rid of them.
