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 touching through with(predicate) it.Water has a high viscosity. This makes it to a great issue 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 object glass immersed in a liquid or gas. It is equal to the weightiness of the liquid or gas displacedThe pertness of water offers protrude 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 t o be able to support themselves. Temperature variationThe main ascendant 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 sole(prenominal) within a certain temperature range.Water heats up to a greater extent slowly than air. Temperatures in the surface ocean layers variegate from 30°C at the equator to freezing point in icy regions. However, the temperature in a particular region varies totally a little from year to year.

Deep waters e rattlingwhere are cold. Small bodies of water may show right smart routine a nd seasonal worker variation.Surface tempera! tures on land vary farther to a greater extent 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 bailiwick (the pull of gravity_...
