Solution
The correct option is B Producers
Consumers survive on food produced by producers. They release CO2 during energy combustion.
Parasites are organisms which obtain the food from the host while harming them.
Decomposers are organisms which obtain energy from dead and decaying matter.
Producers obtain inorganic substances like CO2 and H2O from the environment and convert them to a usable form of energy or food in the presence of sunlight. This process releases oxygen into the environment. They form the first trophic level as they are the first one to produce food in the food pyramid, which can be utilized by other organisms also. Hence, the correct answer is option A.
