Biotherapy may employ organisms, such as protozoa, to consume the bacterial pathogens.

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

The bacterial and fungal channels had the largest energy flow, while the herbivory channel, in which organisms directly consumed plant roots, was smaller.

Plants and other organisms consume the latter.

Bacteria and eukaryotic organisms (zooplankton, algae, fish) consume this oxygen through cellular respiration.

Some hydrothermal vent organisms do consume this "rain", but with only such a system, life forms would be very sparse.

The immediate cause of obesity is net energy imbalance-the organism consumes more usable calories than it expends, wastes' or discards through elimination.

Such organisms may consume by various means, including predation, parasitization, and biodegradation.

The scientists hypothesized that metabolizing organisms would either consume or release at least one of the gases being measured.

Examination of the contents of H.antarcticus stomachs has revealed that these organisms consume mostly small crustaceans and fly larvae.
