Choose given statement is true/false:

Sun is the source of energy in DFC DFC is the major conductor of energy in aquatic ecosystems.

The above given statement is true.

• The sun is the source of energy for all life forms on Earth.
• Organisms in the detritus food chain mostly feed on dead and decaying species of waste created by organisms in the main food chain.
• The dead and decaying organisms can also be plants and plant parts that have perished or are no longer useful; additionally, when animals (who feed on plants) die, their bodies and waste are added to the detritus food chain.
• As a result, we can argue that the sun provides energy to the detritus food chain.
• The DFC organism's primary food source is dead, waste, or decay created by living species.
• The garbage that is produced on the land eventually runs down and settles in water bodies, whether they are rivers, ponds, or the ocean.
• The amount gathered at the bottom of the water body is enormous. The number of bottom-dwelling species in the water that feed on these organisms is huge.
• The organic matter is broken down into inorganic components that can be utilized by aquatic plants and phytoplankton in the water. 
• Some of these species are also prey for animals further up the food chain.

Hence, option is correct.
