Barnacles create home sites by attaching themselves to whales. This neither harms nor benefits the whales. The barnacles eat the plankton that the whale swims past in the ocean. What kind of relationship is this?

• Mutualism

• Parasitism

• Commensalism

Fungi form lichens (a small plant) by living in a close relationship with algae. The fungus provides a protective home for the algae, and gathers nutrients from rainwater. The algae gathers energy from the sun using photosynthesis. Both organisms share nutrients with each other.

• commensalism

• mutualism

• parasitism

• predation

Gall Insects lays their eggs in the leaves or branches of Oak trees. Oak trees provide shelter and food to the insect larvae.

• commensalism

• mutualism

• parasitism

• predation

Honeyguide birds find a bee hive, then chatter loudly to attract the Honey badger. They fly toward the hive making sure the badger is following. Upon arrival at the bee hive, the badger tears open the hive and feasts on the honey. Then the Honeyguide bird feeds on the remaining wax and larvae.

A habitat can best be described as the:

• way an organism adapts

• environment that sustains an organism

• interaction between organisms

• diversity of an ecosystem
