What is the symbiotic relationship between fungus and algae?

A lichen is an organism that results from a mutualistic relationship between a fungus and a photosynthetic organism. The other organism is usually a cyanobacterium or green alga. The fungus grows around the bacterial or algal cells. The fungus benefits from the constant supply of food produced by the photosynthesizer.

Why do whales have barnacles on them?

Whale barnacles attach themselves to the bodies of baleen whales during the barnacles' free-swimming larval stage. Some sources describe the relationship as an example of obligate commensalism.
  • Can barnacles move?

    Adult barnacles have few appendages on their heads, with only a single, vestigial pair of antennae, attached to the cement gland. The six pairs of thoracic limbs are referred to as "cirri", which are feathery and very long, being used to filter food, such as plankton, from the water and move it towards the mouth.
  • What is the relationship between a barnacle and a whale?

    In mutualism, both species benefit from the relationship. In parasitism, only one species benefits from the relationship and causes significant harm to the other. Commensalism, in which only one species benefits without causing significant harm to the other, is the type of symbiosis between barnacles and whales.
  • Where do barnacles like to live?

    Barnacles live only in marine or salt water environments. They live on hard surfaces at all latitudes at all depths from the intertidal zone to the deep sea. (Barnacles in the intertidal region spend part of their day, during low tide, without seawater around them.)
B.

What kind of relationship does the Barnacle have with the whale?

The barnacle-whale relationship is generally considered to be obligate commensalism — a type of symbiosis where one species benefits, and the other isn't affected either way.
  • What does a barnacle do to a whale?

    Whale barnacles attach themselves to the bodies of baleen whales during the barnacles' free-swimming larval stage. Some sources describe the relationship as an example of obligate commensalism. The relationship is parasitic when whales are harmed by the barnacles.
  • What is the symbiotic relationship between a tapeworm and humans?

    Parasitism is a relationship in which one organism - the host - is the source of food and/or shelter for another organism, the parasite. In this relationship, all of the benefits go to the parasite; the host is harmed by the relationship. An example is a human and a tapeworm living in the intestines.
  • What is the symbiotic relationship between sea anemone and clownfish?

    An example of mutualism is the relationship between the ocellaris clownfish that dwell among the tentacles of Ritteri sea anemones. The territorial fish protects the anemone from anemone-eating fish, and in turn the stinging tentacles of the anemone protect the clownfish from its predators.

What is the symbiotic relationship between a tapeworm and humans?

Parasitism is a relationship in which one organism - the host - is the source of food and/or shelter for another organism, the parasite. In this relationship, all of the benefits go to the parasite; the host is harmed by the relationship. An example is a human and a tapeworm living in the intestines.
