Which of the following reason(s) make plants (both terrestrial and aquatic) important for the survival of all life forms?
Producing food for other living organisms
Producing oxygen
Plants carry out a process called photosynthesis by which they produce glucose by using carbon dioxide, water and sunlight. Oxygen is the by-product of this process. Plants and animals inhale this oxygen during respiration. Glucose produced by plants acts as the source of energy for living organisms.
