Question

the carbon cycle
for questions 3 - 5, write true if the statement is true. if the statement is false, replace the underlined word or words to make the statement true. write your changes on the line.

1. only a producer can use the suns energy or chemical energy to make food.
2. the products of photosynthesis are oxygen and carbon dioxide.
3. bacteria, fungi, and other organisms that break down waste are called consumers.
4. why is cellular respiration important for life on earth?
5. what impact do humans have on the carbon cycle?
6. why do scientists think there is an undiscovered carbon sink somewhere?

Explanation:

1. Producers, like plants, can perform photosynthesis to make food using sunlight or chemical energy. This statement is true.
2. Photosynthesis uses carbon - dioxide and water to produce oxygen and glucose, not carbon - dioxide as a product. So, the statement is false. The correct word is glucose.
3. Organisms that break down waste are called decomposers, not consumers. Consumers eat other organisms. So, the statement is false. The correct word is decomposers.
4. Cellular respiration is important because it releases energy (in the form of ATP) from glucose, which is used for various life - processes such as growth, movement, and repair.
5. Humans impact the carbon cycle by burning fossil fuels (releasing carbon - dioxide), deforestation (reducing carbon sinks), and industrial processes.
6. Scientists think there is an undiscovered carbon sink because the amount of carbon dioxide emissions does not match the amount accounted for in the known carbon cycle processes (sources and sinks).

Answer:

1. True
2. False, glucose
3. False, decomposers
4. It releases energy (ATP) for life - processes.
5. Burning fossil fuels, deforestation, industrial processes.
6. Emissions don't match accounted amounts in known processes.
