Part 2-Fill-in: Use the following words to fill-in the blank. Parasitism, Competition, Commensalism, Mutualism, Predation (Predator-Prey)
1. ____________________ is a relationship between two organisms in which ONE species benefits and the other species IS NOT harmed.
Ex: a blue whale and barnacles The barnacles live on the whale’s body and are carried throughout the ocean to find food.
2. ____________________ is a relationship between two organisms in which BOTH of the species benefit from being together.
Ex: a badger and a honey guide bird The honey guide will lead the badger to a beehive and the badger will break open the bee hive with his claws to eat. The badger will always share the honey with the honey guide as a way of thanking him for leading the way.
3. ____________________ is a relationship between two organisms in which ONE species benefits and the other species IS harmed.
Ex: a tick and a dog The tick drinks the dog’s blood.
4. ____________________ is a relationship between two organisms in which ONE species benefits by hunting, killing and eating the other organism.
Ex: a fox and a rabbit The fox often roams its habitat in search of rabbits. Once it catches sight of a rabbit, the fox will sneak up on it, dig its claws into the organism (causing an immediate death) and return to its burrow with its newly found prey.
5. ____________________ is a relationship between two organisms in which ONE species wants the same food, shelter, and mate of another species.
Ex: Giraffes fight for the same mate.
1. Commensalism is a relationship between two organisms in which ONE species benefits and the other species IS NOT harmed.
Ex: a blue whale and barnacles The barnacles live on the whale’s body and are carried throughout the ocean to find food.
2. Mutualism is a relationship between two organisms in which BOTH of the species benefit from being together.
Ex: a badger and a honey guide bird The honey guide will lead the badger to a beehive and the badger will break open the bee hive with his claws to eat. The badger will always share the honey with the honey guide as a way of thanking him for leading the way.
3. Parasitism is a relationship between two organisms in which ONE species benefits and the other species IS harmed.
Ex: a tick and a dog The tick drinks the dog’s blood.
4. Predation is a relationship between two organisms in which ONE species benefits by hunting, killing and eating the other organism.
Ex: a fox and a rabbit The fox often roams its habitat in search of rabbits. Once it catches sight of a rabbit, the fox will sneak up on it, dig its claws into the organism (causing an immediate death) and return to its burrow with its newly found prey.
5. Competition is a relationship between two organisms in which ONE species wants the same food, shelter, and mate of another species.
Ex: Giraffes fight for the same mate.
