Bees pollinating flowers is an example of __________.
Crocodiles competing with lions for food is an example of a __________ relationship.

During a drought, hardly any plant grow so there is little food for the primary consumers. As a result, many of them starve leaving little food for the secondary consumers. This is an example of __________ regulation.
As a result of overhunting, the sea otter population collapses, causing a increase in sea urchin population (their food). Since urchins feed on kelp, the kelp forest disappear as a result. This is an example of __________ regulation.
