What role does nitrogen play to ensure the continuity of life?
nitrogen is the main nutrient for plants without it plants cant survive without plants herbivorous animals cant survive without them carnivorous animals cant survive without either of them omnivorous animals cant survive
How do plants get the nitrogen?
Although nitrogen is abundant in the atmosphere, atmospheric nitrogen features a triple bond that is difficult to break. Bacteria in the soil are mainly responsible for breaking this bond to create organic nitrates that are used by the plants. Such bacteria are called "nitrogen-fixing bacteria" because they take nitrogen from the air (N2) and "fix" it into ammonium (NH4+). Then other bacteria called nitrifying bacteria convert this ammonium to nitrate and nitrite. The nitrates are assimilated by plants through the root systems and incorporate them into nucleic acids and proteins. Animals eat these plants and can use the nitrogen stored within. Then the consumers further up the trophic levels can obtain their nitrogen from the herbivores.
What is the second most element in the atmosphere?
i think its oxogen or like nitrogen. im doing my hw now andi cant find the right answer
Why cant plants absorb gaseous nitrogen?
plants and animals are not adapted to absorb nitrogen from the air. Nitrogen Fixation is a process where nitrogen is changed into a more reactive form for plants and animals to use. There are several ways where nitrogen fixation can happen: lightning, bacteria, carnivorous plants and industrial fixation.
Why doesn't the humans breathe nitrogen?
Because the nitrogen in the air is in a form not usable to animals and plants. The only way animals get nitrogen to build protein and nucleic acid is by eating it. This is usually through plants, which get there nitrogen from the soil. They get it from the soil because bacteria in the soil turn the atmospheric nitrogen into a usable form. In a water ecosystem cyanobacteria (a.k.a. blue-green algae) transform the nitrogen from the atmosphere into usable forms of nitrate
What does the atom of nitrogen look like?
you cant see an atom!
Do animals depend on plants for nitrogen?
Plants and animals depend on nitrogen-fixing bacteria. Plants and animals cannot use nitrogen gas directly. The nitrogen must be changed in to ammonia first. These nitrogen-fixing bacteria take nitrogen and convert it to ammonia for plant and animals to use.
What happen to humans if no plants?
if there is no plants humans cant get oxygen so naturally people cant exist on earth
Why cant plants grow on the moon?
There is no atmosphere of oxygen and nitrogen. Also there is no 'free' water. So there is nothing to support plant ( or animal) life. For life to flourish you need four gases, they are Carbon dioxide, Methane, Ammonia, and Water. Without these four compounds life does not function.
Why cant you breathe on Venus?
It's mostly carbon dioxide and a little nitrogen. We need oxygen and a lot of nitrogen.
Why does the earth never run out of nitrogen in the soil?
cause it cant ha
Are plants autotrophic or hetrotrophic?
plants which cant make their food are called heterotrophic plants
