Question

Decomposers like fungi and bacteria are:

$i$. autotrophs

$ii$. heterotrophs

$iii$. saprotrophs

$iv$. chemo-autotrophs.

Choose the correct answer:

• A. $i$ and $iv$
• B. $i$ and $iii$
• C. $ii$ and $iii$,
• D. $i$ and $i$

Answer 1

The correct option is C $ii$ and $iii$,

Autotrophs

Organisms like plants and certain photosynthetic bacteria that can make their own food are called autotrophs.

Heterotrophs

Organisms like decomposers that depend upon other food sources as they cannot make their own food are called heterotrophs.

Saprotrophs

Heterotrophs like decomposers that derive energy from dead and decaying organisms are called saprotrophs.

Chemo-autotrophs

Autotrophs that can make their own food from organic compounds are called chemoautotrophs.

Final answer

(c) $ii$ and $iii$
