Salazar made a chart to describe some relationships among species. Relationships among Species X, Y Boxing crabs gently carry anemones in their claws to sting predators and keep them away. The anemones feed off bits of food the crab drops. Fleas live on the warm body of a dog, biting the dog and eating its blood. The flea bites cause the dog to itch.
Answer:
X: Mutualism Y: Parasitism
Step-by-step explanation:
It can be seen from the question that the relationship between Boxing crabs and anemones is based on mutualism as the relationship is beneficial to both organisms. The crab used anemones to sting predators and keep them away, while the anemones eat from the crab's food that is dropped.
On the other hand, the flea and dog relationship is parasitic because it is the only flea that is feeding off from dog without the dog getting anything.
