Question

Name the process by which the sun's energy is trapped as the source of energy used by virtually all living organisms

• A. Metabolism
• B. Glycolysis
• C. Homeostasis
• D. Photosynthesis

Answer 1

The correct option is D Photosynthesis

A) Metabolism is the breakdown or synthesis of different metabolites inside the body. It is of two types: Anabolism and catabolism. In anabolism, smaller molecules join together to form bigger molecule whereas, in catabolism bigger molecule is split into smaller molecules.

B) Glycolysis is the breakdown of glucose molecules into pyruvate during cellular respiration.

C) Homeostasis is the maintenance of constant body temperature, in spite of changes in the surrounding temperature. When it becomes too hot outside, our body sweats to cool down the body temperature. When it is too cold outside, our body shivers to raise the temperature.

D) Photosynthesis is the process exhibited by plants, algae and some bacteria called primary producers' that traps energy in the sunlight to produce food. Other organisms depend on producers for their energy needs directly (herbivores) or indirectly (carnivores and other animals).

So, the correct option is 'Photosynthesis'.
