Question

Carbon is taken from the atmosphere through _______. A. combustion of organic material B. photosynthesis C. volcanic activity D. respiration of plants and animals

Answer 1

The right answer is photosynthesis.
Photosynthesis aims to create energy (in the form of carbohydrate) from the light energy from the sun. The organisms that use the photosynthesis mechanism are autotrophic because they make organic materials from inorganic materials, plus Carbon dioxide which is taken from the air.

This reaction takes place through photosynthesis, taking place in the leaves of the plants. Rest activities mentioned in option A, C and D, these all release CO2 into the atmosphere.
