The transfer of energy from one organism to the next in an ecosystem begins with a producer. A producer is an organism that prod
uces its own food. A consumer is an organism in a food chain that obtains energy from producers or other consumers; consumers may be herbivores or carnivores. Which food chain correctly describes the flow of energy in an ecosystem? A) grass→grasshopper→fish→human B) grasshopper→fish→human C) human→fish→grasshopper D) human→grasshopper→fish→grass
A foodchain is used to describe the feeding relationship of organisms present in an ecosystem. It shows "who eats whom" in an ecosystem.
In every food chain the energy gets transferred from the producers to the consumers since the green plants are the producers, it is obvious that the food chain will begin with grass.
Since the grass is eaten by grasshopper it occupies the next trophic level followed by fish and then human.
Therefore, the correct food chain is grass→grasshopper→fish→human
