A fresh water biome food chain is likely to be made up of micro-organisms, decaying substances, detritus, animals without backbones, small fish, large fish, eels and birds. The animals may be present in different species depending on the physical location of the particular biome.Know More
A food chain normally represents the relationship of organisms within a given ecosystem. The food chain shows how each organism is important to the other and the ecosystem as a whole.
At the bottom of the food chain in a fresh water biome one is likely to notice micro-organisms and decaying substances. These are the basic things that enable life to begin. Right on top of these things are likely to be plants such as phytoplankton. On the next level are animals without backbones such as stonefly, midge, caddis and mayfly. These animals are at this position because they are able to eat the plants available.
The next level of the food chain is likely to have small fish which feed on the animals without backbones. Right on top of small fish are large fish which are able to eat both the small fish and some animals without backbones.
On top of the fresh water biome food chain, one is likely to notice birds such as ducks and herons which feed on all kinds of fish.Learn more about Biology
Some bacteria manufacture and absorb their own food, while others must consume substances like living organisms or decaying material through their cell walls. Bacteria break down food in a process called respiration, which for some strains of bacteria requires oxygen to complete.Full Answer >
To create a food web diagram, determine the organisms that make up the top level, secondary and primary consumers, and then determine producers and decomposers. Draw the diagram from top to bottom, and use arrows to indicate the movement of the food web. You need drawing paper and colored pencils.Full Answer >
Vacuoles vary in function between organisms and even within the same cell, but the most frequent use is the storage of water or nutrients. A vacuole is really a general-purpose, empty membrane organelle that is filled with whatever the cell needs to keep separate from the rest of the cytoplasm. As such, different vacuoles also store waste or even toxins, and some organisms have other uses for them.Full Answer >
A food web is a comprehensive map of how energy moves, in the form of food, throughout an ecosystem, while a food chain is one specific path through the web. Most food webs on Earth derive their energy primarily, if not exclusively, from sunlight. That energy is captured by plants via photosynthesis and then distributed to the consumers in the environment.Full Answer >
