Sea Urchin Food Web Alphonse Barba Resource. feeding relationships are often shown as simple food chains – in reality, these relationships are much more complex, and the term ‘food web’ more accurately shows the links between producers, consumers and decomposers. a food web diagram illustrates ‘what eats what’ in a particular habitat. pictures represent the organisms. Sea urchin in natural habitat. sea urchins feed mainly on algae, so they are primarily herbivores, but can feed on sea cucumbers and a wide range of invertebrates, such as mussels, polychaetes, sponges, brittle stars, and crinoids, making them omnivores, consumers at a range of trophic levels. [29].
Ecology The Purple Sea Urchin Resource Sea urchins are primary consumers, meaning that their energy comes from eating primary producers or vegetation. they help keep the ocean’s reefs in good health by consuming the algae before it builds up. an overabundance of algae can suffocate a coral reef and be the kiss of death for the sea life who live there. In kelp forests, sea urchins are the primary consumer of kelp. sea otters prey on urchins. if the sea otter population shrinks due to disease or hunting, urchins devastate the kelp forest. lacking a community of producers, biomass plummets. the entire kelp forest disappears. such areas are called urchin barrens. As billions of sunflower sea stars have wasted away, native purple sea urchin populations have exploded in nearshore waters. these ravenous kelp consumers have sustained more than a 10,000% increase in population along the north coast since 2014. Sea urchins are not known to be primary consumers of plankton. their diet primarily consists of marine plants, such as algae and seaweed. however, it is possible that they may incidentally consume small planktonic organisms present in the water while feeding on algae or detritus.

This study was motivated by the following hypotheses: (1) sea urchins emerged from refuge following the regional collapse of pycnopodia, the 2014–2016 marine heatwave, and a decline in kelp production, (2) sea urchin behaviour (passive or active) explains patch state (forested or barren) transition dynamics and (3) sea urchin migration in. The hawksbill sea turtle is an omnivore, feeding on sea urchins, mollusks, crustaceans and algae. decomposers are bacteria that chemically break down organic matter. a food chain is a set of linkages that show who eats who in an ecosystem and the transfer of energy that takes place. food chains start with a primary producer.
