Question
Which of the following organism forms the base of a food chain?
- Parasitic plants
- Invasive plants
- Saprophytic plants
- Photosynthetic plants
Hint:
Producers are the base of a food chain.
The correct answer is: Photosynthetic plants
Parasitic plants feed on other plants. Hence they are not producers. Invasive plants depend upon organic matter and hence they are also not producers. Saprophytic plants derive their nutrition from dead and decaying organic matter. Hence, they are also not producers. Photosynthetic plants produce food and energy using sunlight and oxygen and hence are producers. Therefore, photosynthetic plants form the base of a food chain.
