Question about nitrogen and phosphorous cycle? Which statements are true, list all that apply
vaieri [72.5K]

Answer: 1) When phosphorous is not bound in rocks, it moves quickly through land food webs. Constant use of phosphate-rich fertilizers will help increase phosphorus availability to plants, thus ultimately helping our ecosystems.

3) Minimizing the use of ammonia-rich fertilizers on lawns would not add excess nitrogen to the nitrogen cycle. As a result, it would help decrease the pollution of food webs in the oceans, decrease soil acidity on land, and decrease the amount of greenhouse gases in the atmosphere

Explanation:

The nitrogen and phosphorus cycles both are biochemical cycles. The nitrogen cycle involves the process of uptake of nitrogen from the atmosphere by the soil bacteria which is then become available to the plants for plant growth, from plants it is transferred to the other organisms in different forms.

The phosphorus is found in the rocks and these rocks wither and the inorganic phosphorus become available to the ecosystems.

Option 1 is correct, this is because the phosphorus is available on earth in the inorganic form inside the rocks, the withering and erosion processes make the phosphorus available to the plants. Another source of phosphorus to plants is phosphorus rich fertilizers. Thus plants will absorb phosphorus and grow. These plants will be consumed by other organisms thus the ecosystem will remain healthy.

Option 3 is correct, this is because nitrogen rich fertilizers can cause eutrophication in water bodies, or can contaminate the water. It will decrease the pH of the soil due to the formation of nitric acid. Also the nitrogen dioxide is the greenhouse gas.

How do monarchs warm up and stay warm?
sp2606 [1]

Answer: Search Results

Featured snippet from the web

Monarchs can warm up by basking in the sun. Basking helps a monarch raise its muscle temperatures to flight threshold. When monarchs bask they open their wings and tilt them toward the sun. Like solar panels, monarchs capture the sun's energy by exposing the surface area of their wings directly to the sun.
