Answer 1

Answer:

Hello Mate!!✌️✌️

HERE IS YOUR ANSWER , hope it helps❤️:

The flow of energy in an ecosystem is always linear ie uni direction. At each energy step in food chain, the energy received by the organisms is used for its own metabolism and maintenance. The left over energy is passed to next higher trophic level. Thus the energy flow decreases with successive trophic level.

Food chains start with a primary producer. Energy is then transferred to a primary consumer, then secondary, tertiary, and quaternary consumers in sequence. The primary consumer is an organism that eats a primary producer, which can include a zooplankton or snail in the ocean.
