Question

archaea is present in deep sea where light cannot reach it. what mode of nutrition it has​

Answer 1

Answer:

Archeabacteria are mainly autotrophic. They can be hetrotrophic also. In the deep sea, they makes their own food from the inorganic chemicals

Answer 2

Archaea can be both autotrophic and heterotrophic.

Explanation:

There are different species of archaea and each one of them can have a different mode of obtaining nutrition.

Some of them are discussed below -

• Chemotrophs - They obtain nutrition from inorganic compounds like sulphur and ammonia. Examples include methanogens, nitrifiers, and anaerobic methane oxidisers.

• Phototrophs - They use light to produce chemical energy. Examples include Halobacteria.

• Autotrophs - They use carbon dioxide present in the environment for carbon fixation via a process called the Calvin cycle. Examples include Crenarchaeota.

Other kinds of archaea are found in guts and swamps like methanogens.
