The Cycling of Chemical Elements In The Ecosystem

THE CYCLING OF CHEMICAL ELEMENTS IN THE ECOSYSTEM

        In the wet cycle, heartiness is supplied by the sun, which drives evaporation either from ocean surfaces or from treetops. peak moves the clouds to different places, otherwise it would only rain at the ocean. haste occurs when water condenses from a bloweous state in the zephyr and falls to earth. Once water condenses, gravity takes over and the water is pulled to the ground. Gravity continues to operate, either pulling the water underground or across the surface. In either event, gravity continues to pull water lower and lower until it reaches the oceans. Frozen water may be trapped in cooler regions of the Earth (the poles, glaciers on mountaintops, etc.) as snow or ice, and may remain as very much(prenominal) for very long periods of time. Lakes, ponds, and wetlands form where water is temporarily trapped. The oceans be salty because any weathering of minerals that occurs as the water runs to the ocean result add to the mineral content of the water, but water cannot abandon the oceans except by evaporation, and evaporation leaves the minerals behind. Organisms play an important subroutine in the water cycle, Most organisms contain a world-shattering amount of water (up to 90% of their body weight).

This water is not held for any length of time and moves out of the organism quite quickly in most cases. Animals and plants lose water by cellular respiration(C H O +6O 6CO +6H O + Energy (ATP + Heat)). In plants, water is drawn in at the roots and moves to the gas exchange organs, the leaves, where it evaporates quickly. This special case is called transpiration because it is responsible for so much of the water that enters the atmosphere. In both plants and animals, the breakdown of...
