In the above food web green algae is the producer, periwinkle and microscopic animals are primary consumers; mussel, barnacle, dogwhelk and crab are secondary consumers; dogwhelk and crab comes under tertiary consumer; dogfish is a quaternary consumer.
What is a food web?
It is a natural interconnection of several food chains in a single ecosystem. Each food chain supplies energy and nutrients through the ecosystem. There are four food webs producer, herbivores, carnivores, omnivores and decomposers.
Here green algae comes under autotrophs(prepares their own food), periwinkle and microscopic animals are herbivores(depend on producer); mussel, barnacle, dogwhelk and crab are carnivores(depend on herbivore); dogfish is an omnivore(depends on both producer and carnivore).
