Question

Detritus food chain involves sub soil organisms while grazing food chain ________.

• A. involves macroscopic organisms
• B. fixes inorganic nutrients to soil
• C. begins with carnivores and ends with decomposers
• D. begins with decomposers and ends with carnivores

Answer 1

The correct option is A involves macroscopic organisms

Detritus food chain starts from the decomposers which feed on dead and decaying organic matter. Thus includes sub soil organisms which derive energy from the detritus, and continues to organisms which can feed them. In grazing food chain, the source of energy is the solar energy and invovles macroscopic organisms which begins from the producers to consumers to carnivores.
