Organisms which obtain energy by the oxidation of reduced inorganic compounds are called
1 Photo autotrophs
2 Chemoautotrophs
3 Saprozoic
4 Coproheterotrophs
Explanation:
The organisms which obtain energy by the oxidation of reduced inorganic compounds are called chemoautotrophs. When the reductants obtains from the environment in inorganic form then organism are chemoautotrophs. - Photoautotrophs make their food by photosynthesis using the energy of sun. - Saprozoic organism obtain food from the dead and decaying matter.

The first organisms to appear on earth were
1 photoautotrophs
2 chemoautotrophs
3 chemoheterotrophs
4 coacervates
Explanation:
The first organisms to appear on earth were chemohetrotrophs. Early chemohetrotrophs did not have the capability of using carbon dioxide from their surroundings to make their own organic compounds. They directly consume organic compounds. They directly consume organic molecules for both a source of carbon as well as energy.

Out of 1.7 million species of living organisms known to us, insects contributes to about
1 0.7 million
2 70000
3 70 lakh
4 One lakh
Explanation:
According to present data, it reveal that 1.7 million living organisms are known to science, in which 1.2 million are animals and 0.5 million are plants. However, Insects have 0.7 million species.
