A) What would happen to ecosystems without producers in the food chain? (1 point)

Without producers, there would be no food for consumers and decomposers. The food chain would collapse.

Without producers, the food chain would only include plants. It would not contain consumers or decomposers.

Without producers, only aquatic ecosystems and their food chains would exist.

Without producers, only consumers and decomposers of ecosystems would survive in the food chain.

Without producers, the entire ecosystem would collapse as there would be no source of energy for organisms to survive. Consumers and decomposers would eventually die off due to lack of food.

The anwers

Without producers in the food chain, ecosystems would collapse as there would be no source of energy for other organisms to survive. Consumers would have no food source, leading to their eventual decline, and decomposers would also suffer since there would be no organic matter to break down. Overall, the entire food chain and ecosystem would be severely disrupted without producers.
