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.

Arpita is very fond of flowers. She visited her grandfather’s house and collected a Water Lily plant for her garden. Arpita plan
Ghella [55]
<h2>Answer:</h2><h3>Lilies do best in a position of full sun, ideally with their roots in rich and fairly moist, yet free-draining soil or compost. Grow oriental lilies in acidic soil or ericaceous compost, and Asiatic lilies in neutral to alkaline soil or multi-purpose compost and not in gardens because most Garden soils are made from three main components: clay, sand and silt. The ideal soil (or loam) has equal amounts of all three, making a fertile soil that is free draining and easy to dig.Which are nothing but making the sand more rougher.So therefore those lillies will not grow in the garden soil and that is the reason why the lillies never grew</h3><h3 />
