Analysis Questions: Cycles of Matter 1. Explain the role of decomposing bacteria in the carbon and nitrogen cycles. In the carbon cycle‚ decomposing bacteria release carbon from the decaying bodies or waste into the atmosphere. Without them‚ it won’t be able for any organism to access the carbon stored in dead bodies. In the nitrogen cycle‚ decomposing bacteria breaks down animal waste‚ which creates ammonia and nitrate products rich in nitrogen. Although no animals or plants cannot directly

Nobre‚ Piers J. Sellers‚ and Jagadish Shukla"‚ there was a significant increase in the mean surface temperature (about 2.5°C) and a decrease in the annual evapo-transpiration (30% reduction)‚ precipitation (25% reduction)‚ and runoff (20% reduction) in the region. Also‚ the deforested case(soil examined from an area) was associated with larger diurnal fluctuations of surface temperature and vapor pressure deficit.

The Effects of Illegal Logging: Illegal logging and associated illegal trade directly threatens ecosystem and biodiversity in forests throughout Asia and the world. It is having a devastating impact on the world’s forests and negatively the economic and ecological system of optimal forest management.

not freque ntly available. Drought is a condition in which soil moisture contents are too low or tightly attracted by soil particle (due to lower osmotic potential) so that plant cannot w ithdraw it or even if it absorbs it cannot meet its transpiration demands. There are different types of dr ought depending upon the growth stage of plant at which it occurs (Seghatoleslami‚ et al. 2007; Sinaki et al. 2007; Kron et al. 2008).

contains war and minerals is called ascent of sap. Water‚ mineral salts and sugar (food) are transported by two methods in higher plants: (1) translocation‚ which is the movement of dissolved substances from one part of the plant to another‚ and (2) transpiration‚ in which water evaporates from the leaves and the subsequent movement of absorbed water takes place through xylem. Water and dissolved salts travel upwards in the xylem vessel‚ while food passes downwards and upwards in the sieve tubes of the
