Water in biology and ecosystems
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.
