What is the primary source of phosphorus in the phosphorus cycle?

• Atmosphere

• Rocks and minerals

• Water bodies

• Plants and animals

What is the role of photosynthesis in the carbon cycle?

• Photosynthesis converts carbon dioxide into oxygen and glucose, playing a key role in the carbon cycle.

• Photosynthesis converts glucose into carbon dioxide and oxygen, playing a key role in the carbon cycle.

• Photosynthesis converts oxygen into carbon dioxide and glucose, playing a key role in the carbon cycle.

• Photosynthesis has no role in the carbon cycle.

What is denitrification in the nitrogen cycle?

• Denitrification is the conversion of nitrogen gas into nitrates by denitrifying bacteria.

• Denitrification is the conversion of nitrogen gas into ammonia by denitrifying bacteria.

• Denitrification is the conversion of nitrates into oxygen by denitrifying bacteria.

• Denitrification is the conversion of nitrates into nitrogen gas by denitrifying bacteria.

How does phosphorus enter the food chain in the phosphorus cycle?

• Phosphorus enters the food chain through evaporation and subsequent condensation in the atmosphere.

• Phosphorus enters the food chain through absorption by plants from the soil.

• Phosphorus enters the food chain through direct absorption by animals from water sources.

• Phosphorus enters the food chain through consumption of phosphorus-rich rocks by animals.

What is the role of nitrogen-fixing bacteria in the nitrogen cycle?

• Nitrogen-fixing bacteria convert atmospheric nitrogen into carbon dioxide in the nitrogen cycle.

• Nitrogen-fixing bacteria convert atmospheric nitrogen into a usable form for plants in the nitrogen cycle.

• Nitrogen-fixing bacteria break down nitrogen compounds into atmospheric nitrogen in the nitrogen cycle.

• Nitrogen-fixing bacteria release nitrogen gas into the atmosphere in the nitrogen cycle.

Why is phosphorus important for plant growth in the phosphorus cycle?

• Phosphorus is not important for plant growth in the phosphorus cycle.

• Phosphorus is only important for animal growth in the phosphorus cycle.

• Phosphorus is important for plant growth in the phosphorus cycle because it is a key component of DNA, RNA, and ATP.

• Phosphorus is important for plant growth in the nitrogen cycle.

This is NOT a part of the phosphorus cycle.

• Phosphate is incorporated into sedimentary rocks

• Phosphate bound to soil

• Atmospheric phosphate

• Phosphate is absorbed from the soil by plants
