Water in biology and ecosystems
MACHINERY OF GOVERNMENT CHANGES
On 21 September 2015, responsibility for water policy and resources was transferred to the Department of Agriculture and Water Resources - Administrative Arrangement Order made on 21 September 2015.
This website will be updated to reflect these changes.
All living things, humans, plants and animals, depend on water to sustain life. Water has a number of critical biological and ecosystem functions.
This key concept investigates the many functions of water in biology from cells to ecosystems including:
- Plant and animal uptake of nutrients and minerals in water
- Water to assist in regulating earth temperature
- Water to help with biological transport functions
- Presence of water as a large part of the make-up of cells and total mass of animals
- Chemical and physical properties of water
- Water as a habitat for both fresh and salt water plants and animals
- Adaption of plants and animals to the availability of water in the environment, for example the ability of camels and baobab trees to store water for dry periods.
