multiple choice pick the answer that best completes the sentence or answers the question.

a. to produce oxygen
b. to produce carbon dioxide
c. store the suns energy in atp
d. store the suns energy in glucose

1. __ organisms, such as plants, that make their own food are called __.

a. consumers
b. heterotrophs
c. producers
d. pigments

1. ____ if carbon dioxide is completely (totally) removed from a plants environment, what would you expect to happen to the plants production of glucose?

a. the same amount of glucose will be produced but without carbon dioxide.
b. carbon dioxide does not affect the production of glucose in plants.
c. more glucose will be produced.
d. no glucose will be produced.

1. ____ a mushroom breaks down a dead tree into small pieces. what is this process called?

a. decomposition
b. cellular respiration
c. combustion
d. photosynthesis

1. ____ we burn coal and oil to make electricity. these energy sources were made mill

Explanation:

1. Photosynthesis uses sunlight, carbon dioxide, and water to produce glucose (stored energy) as its primary product; oxygen is a byproduct, carbon dioxide is an input, and ATP is not the main end goal.
2. Organisms that produce their own food (like plants via photosynthesis) are defined as producers; consumers/heterotrophs rely on other organisms for food, and pigments are molecules that capture light for photosynthesis.
3. Carbon dioxide is a critical reactant for photosynthesis (the process that makes glucose). Removing it entirely stops photosynthesis, so no glucose can be produced.
4. Mushrooms are decomposers that break down dead organic matter (like a dead tree) into smaller components, which is the process of decomposition. Cellular respiration breaks down glucose for energy, combustion is burning organic matter, and photosynthesis makes glucose.

Answer:

1. d. Store the sun's energy in glucose
2. c. Producers
3. d. No glucose will be produced.
4. a. Decomposition
