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.

During glycolysis, when glucose is catabolized to pyruvate, most of the energy of glucose is a. retained in the pyruvate. b. tra
Leona [35]

Answer:

a. retained in the pyruvate

Explanation:

Glycolysis is a cytoplasmic pathway that converts glucose into two pyruvate, releasing a modest amount of energy captured in two substrate-level phosphorylations and one oxidation reaction.

Following are the important enzymes in it :

  1. Hexokinase
  2. Phosphofructokinase
  3. Pyruvate kinase

Aerobic glycolysis yields 2ATP/glucose plus 2NADH/glucose but most of the energy is retained in pyruvate which is then converted into Acetyl-CoA and enters the kreb's cycle.

What is upwelling and why is it important to the marine ecosystem?
xxTIMURxx [149]
Upwelling is a process in which the deep and cold water rises to the water surface and not sea surface. This process plays an important role in maintaining balance in our ecosystem as it boost the marine productivity by washing the nutrients from deeper waters to the photic layer where photosynthesis is promoted.
