Bottom Feeders. The term can be used to describe any organism which primarily dwells and feeds at the bottom on any aquatic habitat. However, it's most often used to describe organisms added to their tanks by aquarium enthusiasts in order to keep their tanks clean. In this case, bottom feeders will either consume the food left uneaten by the tank's main residents or the algae which grows within the tank itself. Examples of bottom feeders available commerically for home fish tanks are Caridina Multidentata, a type of algae eating shrimp, and Ampullariidae or Apple Snails, which consume excess food, rotting vegtation, etc.

Describe the event of eutrophication and what role this plays on aquatic life?
Eutrophication is a process that occurs when a body of water receives an excessive amount of nutrients, primarily nitrogen and phosphorus. This often occurs when fertilizers, sewage, and other sources of nutrients enter the water from runoff or drainage. These nutrients stimulate rapid growth of aquatic plants and algae, resulting in an increase in their populations. This process can cause an overabundance of plant and algae growth, leading to decreased oxygen levels in the water. The decreased oxygen levels can have serious implications for aquatic life. Most aquatic plants and animals require oxygen to survive, so when oxygen levels are depleted due to eutrophication, the survival of many species can be threatened. The decrease in oxygen levels can also lead to an increase in the number of harmful bacteria and other organisms in the water, which can further threaten the health of the aquatic environment. In addition to the direct effects of eutrophication on aquatic life, it can also have indirect effects. For example, when aquatic plants and algae grow rapidly due to excessive nutrients, they can block out light and reduce the amount of sunlight that reaches the bottom of the lake or pond. This can have an effect on the growth of plants and other organisms at the bottom of the lake or pond, as they require sunlight in order to photosynthesize. The effects of eutrophication can be devastating for aquatic life, leading to decreased oxygen levels and reduced growth of plants and other organisms. It is important to take steps to reduce eutrophication in order to protect aquatic life. This can include reducing the amount of nutrients entering the water from runoff or drainage, as well as increasing the amount of vegetation around the body of water to reduce nutrient runoff.
Which level of a energy pyramid has the greatest number of organisms?
Large predators such as bears, lions, sharks, and humans.
What is epistrate feeder?
epistrate is a general term for (micro)organisms that grow on surface of differnt substrates. e.g., microscopic algae and bacteria growing on pebbles or covering the bottom of a river. thus, epistrate feeders are organisms that feed on epistrate. e.g., nematodes and other meiobenthic organisms.
What organisms live in the bottom of the ocean?
Krill Plankton and all sorts of other plants
Why the water lily has broad leaves and a hollow flexible stem?
Lotus is an aquatic plant fixed at the bottom of the pond. To reach the surface of the water lotus stems are thin & hollow.
What is the definition of soft bottom?
Soft bottom refers to an aquatic habitat characterized by a substrate composed of mud, sand, or silt, as opposed to hard surfaces like rocks or coral. Soft bottom habitats are typically found in areas where sediments accumulate, supporting a diverse range of benthic organisms such as worms, clams, and crustaceans.
How does anomalous expansion of water help aquatic organisms in cold climate?
Aquatic life is benefited by the anomalous expansion of water because the water freezes top to bottom, not bottom to top. If it froze bottom to top, then the aquatic life would be pushed up, up, up, towards the surface of the water. Since it goes top to bottom, and the water at the bottom remains at 277K, the Aquatic life can survive there.
What makes a reef?
A reef is an aquatic hard-bottom community or habitat, with topographic relief. Reefs can be made of organisms (ie. coral or oysters), rocks, or man made structures.
Is aquatic frogs bottom eaters?
Their tadpoles are.
Where do scuds live?
In the bottom of fresh water habitats
What is one difference between sandy-bottom and live-bottom habitats?
The sandy-bottom is all sand, and the live-bottom is plant life.
What is a benthic community?
Benthic algae are algae that grow on the bottom sediments of fresh and salt waterbodies. Benthic algae are most commonly filamentous or colonial forms, but also may be microscopic single-celled organisms. Benthic algae perform various beneficial functions. Benthic algae provide food and habitat for many aquatic organisms. In this way they contribute to the biological productivity of aquatic systems.
What must be true about the organisms at the bottom of the food chain?
the organisms in the bottom of the food chain are usually producers.
How do you make a aquatic biosphere?
you would use a bottle and fill it with a live aquatic plant, weter fleas, a snail, and rocks for the bottom.
What kinds of aquatic life are found at the bottom of the ocean?
There is a wide range of aquatic life that can be found at the bottom of the ocean. Bacteria, single-celled protists, and over 4,000 living species of living foraminifera.
Is bottom trawling a destructive fishing practice that destroys ocean habitats?
it is true
Why are hydrogen bonds essential for life?
If it weren't for hydrogen bonds, water would not be a liquid at room temperature, and temperatures common on the earth. Instead it would be water vapor. Also, instead of the unusual property of solid water floating on liquid water, which preserves the lives of aquatic organisms under the ice, ice would be denser than liquid water and would freeze from the bottom up, killing most aquatic organisms.
