A Local Ecosystem:1.The distribution, diversity and numbers of plants and animals found in ecosystems argon determined by biotic and abiotic factors. ?Comp are the abiotic characteristics of aquatic and tellurian environmentsCharacteristicAquatic EnvironmentsTerrestrial EnvironmentsViscosity is a measure of a medium?s electric resistance to an tar swallow area wretched through and through it.Water has a high viscosity. This makes it to a great fulfilment difficult for organisms to move through it.Air has low viscosity. This makes it easier for organisms to move through it. Buoyancy is the amount of concentrate experienced by an aspiration immersed in a liquid or gas. It is equal to the weight of the liquid or gas displacedThe archness of water offers punt to both animals and plants. It may help them to importanttain their shape, and enables some organisms to procedure at different depths.Animals and plants do not experience lots buoyancy from air. They need to be able to support themselves. Temperature variationThe main germ of heat is from the Sun?s radiation. The radiation book depends on latitude. It is greater at the equator than at the poles. Animals and plants can persist unaccompanied within a certain temperature range.Water heats up to a greater extent slowly than air. Temperatures in the surface ocean layers castrate from 30°C at the equator to freezing point in icy regions. However, the temperature in a particular region varies just a little from year to year.

Deep waters e rattlingwhere are cold. Small bodies of water may show coarse routine and seasonal worker variation.Surface tempe ratures on land vary further to a greater e! xtent than in water. The highest recorded in 60°C, and the lowest is slight then -80°C. Daily and seasonal variations may be very great. Temperatures beneath the ground do not vary so much. The ability to avoid or tolerate heat boost and loss is important in land organisms. Pressure variationThe universe?s gravitational battleground (the pull of gravity_...
