To determine which of the statements is true about producers, we need to understand what producers are and their role in ecosystems.

Producers, also known as autotrophs, are organisms that can convert sunlight into energy through a process called photosynthesis. They are the primary source of energy in an ecosystem, as they produce their food by utilizing sunlight, carbon dioxide, and water. Examples of producers include plants, algae, and some bacteria.

Now, analyzing the given statements:

A. They are helpful to some ecosystems and not essential to any ecosystems.
This statement is incorrect. Producers are not just helpful, but they are essential to almost all ecosystems. They provide food and energy for other organisms in the food chain.

B. They are helpful to all ecosystems but not essential to any ecosystems.
This statement is also incorrect. Producers are not only helpful but indeed essential to the functioning of all ecosystems. They form the foundation of the food chain and provide energy for all other organisms.

C. They are essential to some ecosystems.
This statement is partially correct. While it is true that producers are essential to some ecosystems, such as terrestrial or aquatic ecosystems, they are actually essential to all ecosystems.

D. They are essential to all ecosystems.
This statement is correct. Producers are indeed essential to all ecosystems. Their ability to convert sunlight into energy through photosynthesis is what sustains life and supports the entire food chain.

Therefore, the correct answer is D. They are essential to all ecosystems.
