Question

Which of the following is an example of a transducer?
A. Phytoplanktons
B. Zooplanktons
C. Small fish
D. Large fish

Answer 1

The term transducer means anything or any device that is capable of converting one form of energy into another form. Transducers are also termed as sensors, one that can sense various forms of energies.

Complete answer: The transducer is a device that can absorb one form of energy and convert it into another form. Ex. A radio antenna that can convert radio waves into electrical waves. Many devices and technologies developed by humans are derived from nature, for example, the streamlined body of an airplane is inspired by the streamlined body of a bird. Just like this, there are few organisms that act as transducers.
An organism that can inhabit one form of energy and convert it into another form is called a transducer. Ex. Phytoplanktons.
Phytoplanktons are autotrophic (self-producing) marine algae that perform photosynthesis to form energy. It has chlorophyll and uses sunlight for energy production. As they need sunlight, they are mostly found floating on the ocean water so that sunlight can penetrate into their body and they can perform photosynthesis. They use carbon dioxide and light to produce oxygen and energy. Therefore we can say that phytoplanktons are transducers as they convert light energy into chemical energy.

Hence, the correct answer is option A- Phytoplanktons.

Note: Phytoplanktons are the most important organisms in the environmental balance as they are huge in number and also produce oxygen. Oxygen produced by them is taken up by marine organisms. It uses carbon dioxide from the atmosphere to produce energy reducing the carbon dioxide levels in the atmosphere.
