Synthesis of complex organic substances ...

Synthesis of complex organic substances from simple inorganic raw materials in the presence of sunlight and chlorophyll is called as ___ which is a ___ process.

A

photosynthesis, anabolic

B

photosynthesis, catabolic

C

respiration, anabolic

D

respiration, catabolic

Text Solution

Verified by Experts

The correct Answer is:
A
Photosynthesis is an enzyme regulated anabolic process which involves the synthesis of organic compounds, inside the chlorophyll containing cells, from `CO_(2)` and `H_(2)O` with the help of sunlight as a source of energy. Oxygen evolved during photosynthesis comes from water. The equation for photosynthesis can be summarised as follows.
`6CO_(2)+12H_(2) underset("Radiant energy"(686Kcal))overset("Chlorophyll")rarrC_(6)H_(12)O_(6)+6H_(2)O+6O_(2)uparrow`

    Organisms depend on the producers either directly or indirectly for their sustenance ? These organisms which consume the food produced, either directly from producers or indirectly by feeding on other consumers are the consumers. Consumers can be classed variously as herbivores, carnivores, omnivores and parasites. The microorganisms, comprising bacteria and fungi, break-down the dead remains and waste products of organisms. These microorganisms are the decomposers as they break-down the complex organic substances into simple inorganic substances that go into the soil and are used up once more by the plants. Why do all organisms depend on producers for their substances ?
