Which organisms are most critical in the nitrogen cycle?
Bacteria is the organism most critical in the nitrogen cycle. Bacteria in the nitrogen cycle provides different forms of nitrogen compounds used by higher organisms.
What are the four elements that make up one 95 percent of the body in most organisms?
Hydrogen,oxygen, nitrogen, and carbon (in that order) make up over 95 percent of the body of most organisms.
How many elements are common with living organisms?
CHON - the most common are oxygen, hydrogen, carbon, and nitrogen.
What happens to the nitrogen when organisms die?
As the organisms decompose the nitrogen (and most other components) in the body are utilized by any organisms that eat it. Whether that is fungi, bacteria, insects, scavenging animals is arbitrary. All the materials that make up an are mainly Carbon, Hydrogen, Nitrogen and Oxygen along with an assortment of minerals all of which will be recycled in one form or another into other members of the living community. Elements are not destroyed in the process of decomposition but the complex molecules are broken down.
Is Binary fission the most common form of reproduction?
Binary fission is the most common type of asexual reproduction in simple organisms. Examples include organisms such as protists and bacteria.
What elements are most organisms unable to take from the atmosphere?
nitrogen
Do most organisms use nitrogen directly form air?
Since the air around you is about 78% nitrogen gas, you might think it would be easy for organisms to retrieve nitrogen easily. However, most organisms cannot use nitrogen gas. Nitrogen gas is called "free" nitrogen because it's not combined with other atoms. Most organisms can use nitrogen only when it has been combined with other elements to form nitrogen-containing compounds. So, is that the answer you were looking for (possibly for homework)?
What is the large reservoir of nitrogen that is unusable by most organisms?
The air is 80% nitrogen but most organisms are able to extract it from the air.
Is nitrogen rare?
Nitrogen is definitely not rare: In elemental form, nitrogen makes up most of the natural atmosphere, and, in combined form, it is a major constituent of all organisms, because it is a necessary constituent of all proteins; nitrogen also occurs extensively in nitrate minerals.
What are the most organisms unable to take from the atmosphere?
Nitrogen.
Why is nitrogen a limiting nutrient?
This is because the particular form of nitrogen found in air “nitrogen gas“ cannot be assimilated by most organisms. For example, “Nitrogen nutrients are water-soluble and as a result they are easily drained away”, so that they are no longer available for plants.
Which macromolecule provides the most nitrogen for organisms?
Starch Is A Carbohydrate And Starch Provides Nitrogen For Most Plants. So Carbs Is The Answer But Only For Plants.. I Dont Know About All Organisms.
Which organisms are most critical in the nitrogen cycle?
Bacteria is the organism most critical in the nitrogen cycle. Bacteria in the nitrogen cycle provides different forms of nitrogen compounds used by higher organisms.
Where do plants obtain most of their nitrogen?
Unless they are legumes, from the soil.
Can most organisms can use free nitrogen air?
YES!
What gas cannot be used directly your most organisms?
Nitrogen
What gases such as oxygen nitrogen and carbon dioxide are needed by most species?
Oxygen is needed by all organisms for respiration , carbon dioxide is needed by plants for photosynthesis , nitrogen is needed i form of nitrates by plants .
