In the energy flow diagram of an ecosystem, the flow of energy comes to herbivores from:

Correct option is D

The correct answer is (d) producers.
· In an ecosystem, herbivores obtain their energy from producers (plants and other autotrophs).
· Producers capture sunlight through photosynthesis to produce food, which herbivores then consume as their primary energy source.
Information Booster:
· Sunlight: The initial energy source in an ecosystem, which is harnessed by producers.
· Carnivores: Obtain their energy by consuming herbivores.
· Top carnivores: Sit at the highest level of the food chain and obtain energy by preying on other carnivores or herbivores.
