The nitrogen cycle _________. A. indicates the process of uptake of nitrates (NO₃ minus) by plants.
B. marks transformation of ammonium (NH₄ plus) into nitrites (NO₂ minus) by bacteria.
C. marks synthesis of ammonium (NH₄ plus) by decomposers.
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
E. marks organisms that take part in transformation of nitrogen from the atmosphere (N₂) into ammonium (NH₄ plus) and are located in the root nodules.

Answers

Answer:

D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.

Explanation:

The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).

The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.

Hence, the correct option is D.

Which is one source of the sediments that form sedimentary rocks?chunks of coal
particles in new rocks
liquid magma
materials dissolved in solutions

Answers

Most sedimentary rocks are formed in a process that involves water. It is one of the primary factors in the mineral formation of chemical sedimentary rock. Thus, option D is correct.

What role of dissolved materials in the sedimentary rocks?

Mineral crusts are formed on the sedimentary grains as a result of dissolved minerals in groundwater precipitating (crystallizing) from water in the pore spaces and eventually cementing the sediments to create a rock.

Chemical sedimentary rocks are created when minerals precipitate from water. When dissolved substances leave water, it precipitates. Take a glass of water and add some salt (halite), for instance.

Additionally, it acts as an erosive and weathering agent, generating the grains that eventually form detrital sedimentary rock.

Therefore, materials dissolved in solutions is one source of the sediments that form sedimentary rocks.

Biological pest control methods supplement but cannot replace chemical pest control methods.t/f

Answers

This is false. Farmers of organic food have been doing this for a whileand it has become a trend. Food grown this way is usually a lot moreexpensive but the evidence that the food made in this manner ishealthier still up for debate as inconclusive results have been found,pointing out that there's really not that much of a difference.

Answer:

False

Explanation:

Biological pest control methods are used to control the population of pest below a level where it cannot damage the crops. Instead of using chemicals (which lower the soil quality), living organisms (which are predator, parasite, herbivore etc.) are introduced in the crop field to keep a check on population of damaging pest or weeds

This is an organic method of gardening where a beneficial organism is chosen to control the harmful pest

Hence, given statement is false
