fixed nitrogen

Too much fixed nitrogen can do all three to some degree or other.

Human activity also moves existing fixed nitrogen around ecosystems in surprising ways.

This latter then circulates the fixed nitrogen to the rest of the plant.

In addition to runoff from land, atmospheric fixed nitrogen can enter the open ocean.

The extra availability of fixed nitrogen in the plant makes its leaves more nutritious.

Today, about 30% of the total fixed nitrogen is manufactured in ammonia chemical plants.

Chase orders him to inject the pod with fixed nitrogen.

It has since been replaced by fixed nitrogen from the air as the main source of nitrogen.

The electrified rain delivered a shot of properly fixed nitrogen right into the soil.

It is thus a major sink for fixed nitrogen and so limits oceanic primary productivity.

The amino acids are then shuttled back to the plant with newly fixed nitrogen.

Heterocysts may also form under the appropriate environmental conditions (anoxic) when fixed nitrogen is scarce.

Artificial fertilizer production is now the largest source of human-produced fixed nitrogen in the Earth's ecosystem.

A thunderbolt fixed nitrogen that nourished a forest.

The addition of sulfur and fixed nitrogen converted the barren zone to a rich plant bed for terraform life.

A diazotroph is an organism that is able to grow without external sources of fixed nitrogen.

However, fixed nitrogen may circulate many times between organisms and the soil before denitrification returns it to the atmosphere.

Up to 60% of the cells can become heterocysts, providing fixed nitrogen to the plant in return for fixed carbon.

The relationship is symbiotic because the plant supplies the energy by photosynthesis and benefits by obtaining the fixed nitrogen.

Heterocyst formation is inhibited in the presence of a fixed nitrogen source, such as ammonium or nitrate.

In addition to green algae, the lichen contains cyanobacteria that help contribute to soil fertility by supplying fixed nitrogen.

Soft-rot fungi need fixed nitrogen in order to synthesize enzymes, which they obtain either from the wood or from the environment.

The levels of ureide nitrogen in a plant correlate with the amount of fixed nitrogen the plant takes up.

Higher organisms consume the fixed nitrogen to synthesize amino acids, nucleotides, and other nitrogen-containing biomolecules.

Scytonema is a nitrogen fixer, and can provide fixed nitrogen to the leaves of plants on which it is growing on.
