Path of energy flow in an ecosystem is :-a)Herbivores →Producers ...
Correct answer is option 'd'. This can be easily understood as the producers (plants) prepare food with the help of photosynthesis in which the energy is absorbed from sun. That solar energy is stored in food but at every next food chain level, only 10% of it is transferred. Now herbivores (plants/leafs/grass eaters) uses producers for energy and those herbivores in turn are eaten by carnivores for energy. When all these die, they are decomposed by decomposers which also recieves a few part of the same energy which was consumed at the level of producer. In this way energy flow through the food chain.

Above link shows the food chain, which shows the relationship among species of an ecological system.
The producers include all the green plants, which manufacture their own food through photosynthesis.
The primary consumers include herbivorous animals like deer, goats, mice and all plant-eating animals.
The carnivores include all the flesh-eating animals like snakes, tigers and lions.
Decomposers are those that feed on dead organisms, and further breaking down of the dead matter by other decomposing agents like bacteria and various micro-organisms.
The producers are consumed by the primary consumers whereas the primary consumers are, in turn, being eaten by the secondary consumers. Further, the secondary consumers are consumed by the tertiary consumers. The decomposers feed on dead at each and every level.
