Estuaries can experience fairly extreme changes in abiotic conditions. For example, estuaries can at different times be dominated by the ocean when freshwater input from upstream is minimal, or it can be freshwater dominated when there is a lot of flow coming into the estuary from upstream. This means that organisms that exist within estuaries must be able to tolerate a wide range of salinities. These are called euryhaline organisms. Estuary ecosystems also receive biotic inputs from both the ocean and from the upstream river. There are therefore a lot of scavengers that thrive within estuaries, such as crabs, mud prawns and clams. One primary producer group that is important for estuaries are mangroves, but they are not found in all estuaries. Estuaries act as important nursery areas for ocean fish, who come into the estuary to spawn.

Atoms are the most basic unit of matter that makes up elements. Atoms are made up of electrons orbiting a nucleus comprising protons and neutrons.
The<u> atomic numbe</u>r, is defined as the number of protons in an atom, while the <u>atomic mass</u>, is the number of protons and neutrons.
In reaction, atoms are not created or destroyed, the atoms simply become rearranged in new formats; molecules are two or more atoms bonded together. Different molecules can join together to form compounds.
