An organism that obtains energy and nutrients by feeding on other organisms or their remains. A food web is a model of the feeding relationships between many different consumers and producers in an ecosystem. Without plants (the primary producers) consumers and decomposers would not be able to live. Producers always start every food chain.

Answer:
The correct answer would be B) the flow of water through the body of a sponge.
Sponges are multi-cellular organisms which are devoid of organ systems like digestive system, nervous system, circulatory system et cetera.
They have a unique feeding system in which they keep constant water flow through their bodies. They obtain food and oxygen and remove waste through this water movement.
The movement of water throughout the sponge is unidirectional in nature. It enters the sponge body through ostia and exit from the osculum.
As the water is pumped out, the cells present in the walls filter out the food present in the water.
