Assertion: Chemosynthetic autotrophic bacteria play a great rolie in recycling nutrients like nitrogen, posphorous, iron and sulphur.
Reason: Chemosynthetic autotrophic bacteria oxidise various inorganic substances to obtain energy.

Assertion : Chemosynthetic autotrophic bacteria oxidise various inorganic substances. Reason : Energy released during oxidation is used in ATP production.

Asseration : Chemosynthetic autotrophic bacteria oxidise various inorganic substances. Reason : Energy released during oxidation is used in ATP production.

Some chemosynthetic bacteria use energy obtained from oxidising

Asseration : Chemosynthetic autotrophic bacteria oxidise various inorganic substances. Reason : Energy released during oxidation is used in ATP production..1If both assertion and reason and true and reason is the correct explanation of assertion.2.If both assertion and reason and true and reason is not the correct explanation of assertion.3.If assertion is true but reason is false. 4.If both assertion and reason are false

Assertion : None autotrophic bacteria carry out chemosynthesis. Reason : Chemosynthesis bacteria trap the small amount of energy released from inorganic compound's oxidation to use in the reaction that synthesize carbohydrates.

Read the statements (A) Chemosynthetic autotrophs like hydrogen bacteria oxidize molecular hydrogen to water are called as organotrophs (B) Chemosynthetic bacteria do not have photosynthetic pigments (C) Chemosynthetic autotrophs like iron bacteria oxidize ferrous to ferric are called as lithotrophs
