|
|
Viscosity on terrestrial environments
|
Easier for animals to move through air then water
|
|
|
|
Aquatic environment
|
They usually have a streamline shape to assist them moving through water
|
|
|
|
Buoyancy on terrestrial environments
|
Air offers some buoyancy , adaptations such as wings are needed to make use of this
|
|
|
|
Buoyancy on Aquatic environments
|
Water is more buoyant then air, water not only hold the organism up bit can also assist in maintains their shape (jellyfish)
|
|
|
|
Temperature variation on aquatic environment
|
Temperature of water does not experience much variation even in small amounts of water. Small changes can have massive consequences , an advantage however is that it is easier to adapt to a constant environment therefore more conductive to life
|
|
|
|
Temperature variation on terrestrial
|
Huge variations are common, in a day variations may be between 15-20 degrees, far greater fluctuations occur in deserts
|
|
|
|
Conduction of heat terrestrial
|
Water conducts heat better then air
|
|
|
|
Ability of gases aquatic
|
Oxygen & carbon dioxide dissolve in water, gases are most abundant in cases where water is turbulent. As water depth increases the gases decrease
|
|
|
|
Diffusion of gases terrestrial
|
10,000 faster in air then water this is an advantage for rapid movement of gases
|
|
|
|
Availability of water aquatic
|
Water surrounds the organisation but it is not as readily available
- Fresh water environments: more water enters cells by osmosis than leaves it - marine environments: more water leaves the cells by osmosis then enters it |

|
|
|
Availability of ions aquatic
|
Ions are available in abundance, convection currents carry ions from decomposed organisms to the surface

|
|
|
|
Availability of ions terrestrial
|
Ions and salts are available in soil waters. Plants absorb through roots and animals through eating plants
|
|
|
|
Light aquatic
|
- Water absorbs light , as depth increases light decreases
|
|

|
- Water absorbs light , as depth increases light decreases
|

|
|
Light terrestrial
|
Available in abundance and is only scarce in rainforest floor

|
|
Pressure variation aquatic
|
- Pressure does not fluctuate but their is constant variation as. Water depth increases pressure increases
- pressures are great on ocean floor - |
