How can food webs change?
Living things in a food web depend on one another. Suppose the population of one organism in a food web changes. A population is all the members of a single type of organism in an environment.Kelp ForestsWhen one population in a food web changes, all the populations in the food web can also be affected. This is what happened in the ocean's kelp forests. Kelp is a type of seaweed. Kelp forests are home to thousands of ocean creatures. Some kelp forests have been greatly changed by just one animal. That animal is a sea otter. Sea otters eat several animals in their ocean food web. They eat sea stars, sea urchins, mussels, crabs, and large fish. The kelp forests were almost destroyed when the sea-otter population changed about 200 years ago.A Sea Without Sea OttersWhat happened to the kelp forests? In the 1800s, too many sea otters were hunted for their fur. Without sea otters, fewer sea urchins were eaten. Soon, too many sea urchins were being born. Smaller fish could not survive, because sea urchins ate their supplies of kelp. These fish were food for sea stars and crabs. The sea stars and crabs began to die out.Mussels also depended on kelp to stay alive. Fewer mussels meant fewer crabs and large fish that depended on mussels for food. After a while, even decomposers could not survive. Without the sea otter to help control the size of the sea-urchin population, the kelp forests almost disappeared.In the 1900s, many countries agreed to stop hunting sea otters. The kelp-forest food web became balanced again. Now, new food-web changes are putting kelp forests in danger again.

Is a penguin a consumer or decomposer or producer?
The plants (producers) are needed by consumers who feed by grazing or filter-feeding. Examples include snails, urchins and corals. These consumers in turn will be eaten by other animals such as sea stars. At the top of the food web, there are larger animals (consumers) such as fish, penguins, seals and whales.

How is a food web difference from a food chain?
A food chain is a sequence of links from one species to another in a food web. Food chains show links from producer to consumer organisms. For example: aquatic vegetation ---- fish ------- seagull On the other hand a food web shows interconnections between food chains. For example: aquatic vegetation ----------- fish --- seagull or fish ----- larger fish -------- sea eagle In this food web there is a link from fish to seagull and also a link from fish to larger fish to sea eagle
