Question

1. which of the following is not true about matter in the biosphere? *

human activity does not affect the movement of matter
matter is transferred in one direction through the biosphere
biogeochemical cycles transform and reuse molecules
the total amount of matter decreases over time

1. which of the following explains the role of plants in the carbon cycle? *

plants transfer carbon in the atmosphere to carbohydrates in the biosphere
plants transport carbon dioxide in the atmosphere to ground water
plants transfer oxygen and carbon dioxide in the biosphere to carbon dioxide in the atmosphere
plants transfer oxygen in the atmosphere to fossil fuels

Explanation:

• Question 4:
• Human activities like deforestation and burning fossil fuels affect matter movement. Matter is cycled (not transferred one - directionally), biogeochemical cycles transform/reuse molecules, and matter is conserved (total amount doesn't decrease).
• Question 5:
• Plants take in \(CO_2\) from the atmosphere and through photosynthesis convert it to carbohydrates (\(C_6H_{12}O_6\)). They don't transfer \(CO_2\) to groundwater in the carbon - cycle context as described in option 2, option 3 has an incorrect transfer (oxygen is a by - product of photosynthesis, not transferred as stated), and plants don't transfer oxygen to fossil fuels.

Answer:

• Question 4: Human activity does not affect the movement of matter
• Question 5: Plants transfer carbon in the atmosphere to carbohydrates in the biosphere
