Question:

Consider the following statements.

I. Producers are also called as transducers because they are able to change radiant energy into chemical form.

II. Consumers are animals, which feed on other organisms or their parts.

III. Decomposers are saprotrophs, which feed on dead bodies of organisms.

Which of the statements given above are correct?

Options:

I, II and III

I and II

I and III

II and III

Correct Answer:

I, II and III

Explanation:

The correct answer is Option (1) - I, II and III

Statement I: The statement is correct. Producers, such as plants and some bacteria, are able to convert radiant energy from sunlight into chemical energy through the process of photosynthesis. This energy is stored in the form of organic compounds, such as carbohydrates, which can be utilized by other organisms in the ecosystem.

Statement II: The statement is correct. Consumers are organisms that obtain their energy and nutrients by feeding on other organisms or their parts. They can be herbivores, carnivores, or omnivores, depending on their feeding habits.

Statement III: The statement is correct. Decomposers, such as fungi and bacteria, are saprotrophs that obtain their nutrients by breaking down dead organic matter. They play a crucial role in the process of decomposition, breaking down complex organic compounds into simpler inorganic substances and recycling nutrients back into the ecosystem.

Therefore, the correct answer is (1) I, II, and III.
