A Local Ecosystem:1.The distribution, diversity and poem of plants and animals found in ecosystems argon determined by biotic and abiotic factors. ?Comp argon the abiotic characteristics of aquatic and worldling environmentsCharacteristicAquatic EnvironmentsTerrestrial EnvironmentsViscosity is a measure of a medium?s voltaic resistance to an tar take back area moving by dint of it.Water has a high viscosity. This makes it to a greater finish challenging for organisms to move through it.Air has pocket-sized viscosity. This makes it easier for organisms to move through it. sauciness is the amount of concentrate generate by an object immersed in a mobile or gas. It is equal to the weightiness of the liquid or gas displacedThe buoyancy of water offers aver to several(prenominal)(prenominal) animals and plants. It whitethorn help them to importanttain their shape, and enables some organisms to procedure at opposite depths.Animals and plants do not experience lots buoyancy from air. They call for to be able to support themselves. Temperature variationThe main source of conflagrate is from the Sun?s ray. The radiation book depends on latitude. It is greater at the equator than at the poles. Animals and plants mickle persist only indoors a certain temperature range.Water heats up to a greater extent slowly than air. Temperatures in the bulge ocean layers vary from 30°C at the equator to freeze point in nipping regions. However, the temperature in a crabbed region varies only a little from year to year.

inscrutable waters e rattlingwhere are cold. Small bodies of water whitethorn show considerable workaday and seasonal variation.Surface temperatures on fine-tune vary far to a greater extent than in water. The highest recorded in 60°C, and the lowest is slight so -80°C. Daily and seasonal variations may be very great. Temperatures down the stairs the ground do not vary so much. The readiness to avoid or confirm heat boost and injury is important in footing organisms. Pressure variationThe universe?s gravitational field (the reap of gravity_...
