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.

Can amoeba have offspring with different genes and traits
stepan [7]

Here is your answer

No

______________________________

REASON:

Amoeba reproduces by the process of binary fusion which is an asexual mode of reproduction.

Since, in asexual method mitosis cell division takes place, same DNA material is transferred to the offsprings so no new traits and genes can be found in offsprings.

However in some case due to genetic drift or mutation, slight variations can be found in progeny.

But this is very exceptional.

A team of scientists conducted a study of grassland ecosystem and estimated the total energy at each trophic level. Their data i
maria [59]

Answer:

In grassland ecosystem, first trophic level is the producer. Producers are the organisms which makes their own food, here the producer are grasses. The second trohic level contain herbivores which feed on these grasses. These herbivores are eaten by secondary consumers which belongs to third trophic level and secondary consumers are then eaten by tertiary consumer.

The population of producers are very high so it is placed at the base while tertiary consumer are placed on the top due to low population.
