How does the transfer of water mimic the transfer of energy thru an ecosystem?

This illustration shows how water transfer imitates energy transfer through an ecosystem.

Note here that just as there is energy loss in the transfer of energy, there is also water reduction in the transfer of water.

A student is to dip cup 1 in the first container loaded with water. He will at that point move the water from cup 1 into cup 2 which is in his left hand. There will be a dim plate/ container under his left hand  to hold water coming from the openings in cup 2, exchange the water in cup 2 to his partner who is holding cup 3 and they will proceed with the water transfer until they arrive at the last container.

They may notice that there is going to be a considerable amount of water reduction from the first container to the last container.

Explanation:

Energy moves through ecosystems a single way from photosynthetic living beings. The all out energy found in living beings from one tropic level in a natural way of life is accessible to life forms in the following tropic level as just a part of energy reduction; the rest is used in metabolic cycles or changed into heat.

the correct option is option d

energy and particles
