Symbiosis

How is commensalism different from mutualism?

• In commensalism, one species benefits while the other is unharmed; in mutualism, both species benefit

• In commensalism, one species is harmed while the other benefits; in mutualism, both species benefit

• In commensalism, neither species is harmed; in mutualism, one species is harmed

• In commensalism, both species benefit; in mutualism, one species is harmed

• Parasitism

• Mutualism

Barnacles create home sites by attaching themselves to whales. This relationship neither harms nor benefits the whales. 

• parasitism
• commensalism
• mutualism

Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds. Both species benefit. 

• parasitism
