Why does a food web provide a better model of an ecosystem than a food chain?

• A food web is a better model as it shows how organisms are interconnected in an ecosystem. It shows how one organism can have more than one role in an ecosystem.

• A food web is a better model as it shows how organisms are not connected in an ecosystem. It shows how one organism can only have one role in an ecosystem.

• A food web is a better model as it shows organisms.

• None of these

What is the primary function of decomposers in an ecosystem?

• Decomposers combine elements, such as carbon, nitrogen, and oxygen, into complex molecules that can be used as food sources for organisms.

• Decomposers break down matter from dead organisms into simpler substances that can be recycled in ecosystems.

• Decomposers are parasites; they attach themselves to host organisms and absorb nutrients from the host until the host organism dies.

• Decomposers absorb energy from the Sun and produce food for themselves as well as other organisms.

• I don't know.

• There will be an increase in the number of crustaceans which will cause a decrease in the shark population.

• There will be a decrease in the number of crustaceans which will cause a decrease in the fish population.
