Answer:
Competition - two species of mussels relying on the same species of phytoplankton as a food source
Mutualism - interactionalgae obtaining nutrients from symbiotic coral, and coral obtaining sugars from algal photosynthesis
Parasitism - interactiona tick sucking a dog's blood
Herbivory - a rabbit eating the leaves of a dandelion plant
Predation - cheetah capturing and consuming a gazelle
Explanation:
Two species compete when they depend on the same resources and these resource are scarce in the habitat
Two organism undergoing mutualism benefit each other
Parasitism - in this only one organism is benefitted while the other one is harmed
Herbivory - In this an organism feed upon animal produce
Predation - One strong animal/organism feed upon another weak/smaller animal or organism
