Answer 1

Answer:

Nutritional Types and Bacteria's

The following points highlight the four major nutritional types of bacteria. The types are: 1. Photoautotrophs 2. Photoheterotrophs 3. Chemoautotrophs 4. ...

In the first step ammonia is oxidized into nitrites by the bacteria Nitrosomonas, Nitrococcus:

This is brought about by the bacteria Nitrobacter, Nitrocystis:

Answer 2

The categories of nutrition obtained by bacteria and protists are described below :

1. In Bacteria

a) Photoautotrophs

The bacteria of this group gets energy from the light of sun. Example is Cyanobacteria.

b) Photoheterotrophs

They get energy from the light. Example is purple bacteria.

c) Chemoautotrophs

They obtain energy from ammonia, hydrogen, etc, which are the inorganic compounds. Example is many Archeae.

d) Chemoheterotrophs

They get energy from the organic type of compounds.

2. In Protista

They obtain nutrition by both autotrophic and heterotrophic modes.
