Decomposers are important in the environment because they

• convert large molecules into simpler molecules that can then be recycled

• release heat from large molecules so that the heat can be recycled through the ecosystem

• can take in carbon dioxide and convert it into oxygen

• convert molecules of dead organisms into permanent biotic parts of an ecosystem

A particular species of unicellular organism inhabits the intestines of termites, where the unicellular organisms are protected from predators. Wood that the termites eat is digested by the unicellular organisms, forming food for the termites. The relationship between these two species can be described as

• harmful to both species

• parasite/host

• beneficial to both species

• predator/prey
