Ecological Relationships

Algae and Fungi (Lichen)

Algae and fungi can live together, forming

lichen. The algae produce carbohydrates

through photosynthesis, providing nutrients to

both the algae and the fungi. The fungi provide

moisture for the algae.

Mosquitoes and Human

Mosquitoes find a human and feast upon their blood. This causes a small reaction on the human’s skin, resulting in a red, itchy bump. In addition, mosquitoes can pass along disease to their human host.

Anemone Hermit Crab and Anemones

The crab attaches several anemones to its shell using them as camouflage and as a deterrent to potential predators. The anemones have a “mobile home” and get more exposure to food than if they remained stationary.

Alligator and Deer

A lucky alligator spots a deer drinking water, attacks the deer, kills it, and eats it for food.

Tapeworm and dogfish shark

A tapeworm lives in the intestines of a dogfish shark and takes nutrients from the shark. As a result, the shark is weakened and more vulnerable to disease and predators.

Maribou Stork and Bees

The stork uses its saw-like bill to cut up the dead animals it eats. As a result, the dead animal carcass is accessible to bees for food and egglaying.
