Lake ecosystem - Wikipedia
Dec 21, See the amazing symbiotic relationship that has evolved between jellyfish levels, creatures like the golden jellyfish trickled into an island lake. People who visit a lake, river, or stream usually pay attention only to the surface. In the flat, mud bottom I could see roots of pond lily and the carcasses of water- logged benefit from their interaction are known as a symbiotic relationships. Ecology - Interactions in Communities.

As the sun moves across the sky from East to West, so do the Jellyfish traverse the lake to the West until sundown when the jellyfish then drift to the bottom.
They swim across the lake to the East at night and the process starts again the next morning. Coral are also symbiotic in that algae live inside their gastric cavities as well and give them color.

They are coated in mucous, which protects them from the anemone's stinging nematocysts. Other animals like crabs and shrimps also seek protection in anemones. The Anemone crab lives in the anemone's tentacles and catches its food without ever leaving the safety of the tentacles.
Another example of commensalism can be seen with the Man-of-War fish and the Portuguese Man of War jellyfish. Cooperation within the sea abounds and sometimes takes a very unusual form. Some Imperial shrimps will actually ride on sea cucumbers, hopping off when they want to feed in certain areas.
When the shrimp is ready to go to another area, it will hop back on the cucumber and be taken to the next place without using very much energy.
Types of Symbiotic Relationships
Sometimes Imperial shrimp will ride on other animals like nudibranchs, and these animals offer protection to the shrimp because they are poisonous to other animals. Several species of sea cucumbers host the Pearlfish inside their intestines during the day. At night, the Pearlfish swims out of the anus of the sea cucumber to eat crustaceans. The sea cucumber doesn't seem to mind this odd guest and the Pearlfish is relatively safe during the day.
Parasitism More often than not, parasites are harmful to the host organism. Ectoparasites live on the outside of the host and endoparasites live on the inside of the host.
Ectoparasites are often crustaceans in the order Isopoda or Copepoda. Isopods have adapted strong suckers, flat bodies, and sharp jaws used to attach to their host. They tend to molt in stages so that they remain latched on to the host.
Symbionts, Parasites, Hosts & Cooperation
Some isopods will attach to the fish and cause no harm. In this case they eat particles of food that float by rather than feed on the host directly. Mutualism Mutualism is a symbiotic relationship in which both species benefit. For example, some anemones share a mutualistic relationship with Boxer crabs, Lybia tesselata. Alga, a single-celled plant, is what makes the freshwater sponge green.
Algae help provide oxygen and food for the sponge. In return, the sponge gives algae a place to live. Situations where two organisms benefit from their interaction are known as a symbiotic relationships. Distribution and size Approximately species of freshwater sponges are found throughout the United States, usually in clear, shallow waters of ponds, lakes, and slow-moving stream backwaters. Several sponge species exist in Montana, including Spongilla lacustris shown above.
Most freshwaters sponges are a few inches long and form as encrustations on twigs or other hard surfaces. Structure For centuries, sponges were considered plants because of their primitive structure and lack of mobility.
Their cell layers are not organized into tissues or organs. Various types of microscopic specialized cells— including sclerocytes, flagella, pinacocytes, and myocytes—work together to help the organism survive.
