The nitrogen in the air cannot be used by producers and consumers. It must be fixed or converted by bacteria in the ground into a useable form for plants called nitrates. Some plants called legumes (beans and clover) actually have bacteria in their roots.
I'm pretty sure it's all of the above but i'd have to say body fluid has the most water

Diifer in only one trait.
Answer:
Explanation:
Semiconservative replication is one of the type of replication methods proposed to take place in the cell and has also been confirmed to be the type that actually takes place in the cell. Semiconservative replication involves the production of two copies (of which one is the parental strand which acts as template and the other is the newly synthesized strand) of the original DNA molecule. A leading strand is the newly synthesized strange running in the 5' to 3' direction, the template strand runs from the 3' to 5' direction while the lagging strand is the newly fragmentally synthesized strand oriented in such a way that its production runs in the 5' to 3' direction for each okazaki fragment. Its template strand runs in the 5' to 3' direction.
The cell copes with errors in replication either by performing the 3' to 5' exonuclease proofreading during replication or by utilizing the cell's DNA repair system.
