Question 11

A student placed a test tube containing elodea (an aquatic plant) and pond water 10 cm from a light source. He observed that the plant gave off bubbles of a gas and counted how many bubbles were released in one

minute. He moved the plant farther away from the light source to see if the distance from the source made a difference. The data table below shows his

results.

The gas that was being produced was most likely

Accepted Answer

oxygen as a product of the process of photosynthesis

Answer

carbon dioxide as a product of the process of respiration

Answer

carbon dioxide as a product of the process of photosynthesis

Answer

oxygen as a product of the process of respiration

Question 12

A student designed an experiment to determine if air temperature had an effect on the

rate of photosynthesis in corn plants. Which tool is correctly paired with a procedure that could be used during this experiment?

Accepted Answer

a graduated cylinder to measure 30 mL of water for each plant daily

Answer

an electronic balance to measure the volume of soil in which each corn plant is grown

Answer

a metric ruler to determine the mass of each plant each week

Answer

a Celsius thermometer to determine the pH of the soil

Question 13

A student designed an experiment to determine if air temperature had an effect on the

rate of photosynthesis in corn plants. The independent variable in this experiment is the

Accepted Answer

air temperature at which the corn plants were grown

Answer

amount of carbon dioxide used by the corn plants

Answer

volume of oxygen produced by the corn plants

Answer

number of corn plants used

Question 14

The graph below shows changes in dissolved oxygen in a pond in the summertime over a 24-hour period. What is the most likely reason for the variation in the dissolved oxygen levels in the pond over the 24-hour period?

Accepted Answer

Photosynthesis produces more oxygen during the day than is used by respiration.

Answer

The increased light during the day decreases the oxygen produced by photosynthesis.

Answer

Respiration is reduced at night, so the oxygen produced by photosynthesis increases.

Answer

More producers are active at night, so the dissolved oxygen increases.

Question 15

A large population of fish was introduced into the pond. During which part of the day would these fish affect the dissolved oxygen level in the pond?

Accepted Answer

both day and night, because respiration is occurring all the time in plants and animals

Answer

nighttime, because no respiration is occurring

Answer

daytime, because that is when plants are most active

Answer

neither day nor night, because only plants produce oxygen

Question 16

Carbon dioxide and oxygen are important

resources in ecosystems and are

Accepted Answer

recycled through the activity of living and

nonliving systems

Answer

stored in the animals of the ecosystem

Answer

lost due to the activities of decomposers

Answer

released by the process of photosynthesis
