Environmental and Chemical Processes

In chemistry, 'analysis' specifically refers to the process of breaking down a chemical compound into its constituent elements. This is the opposite of 'synthesis,' which involves combining elements or simpler compounds to form more complex ones. Symbiosis is a biological term, and photosynthesis is a specific biochemical process.

Bioremediation is the branch of biotechnology that uses biological process to overcome environmental problems.

Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N₂), completing the nitrogen cycle.

The process by which metabolic wastes are eliminated from the body is called excretion. Metabolism includes the sum of all the chemical reactions that take place in our body. The breakdown of proteins produces nitrogenous wastes like ammonia, urea and uric acid. The elimination of such wastes from the body is termed as excretion. Nutrition is a process by which the organisms obtain those substances, which are utilized for their growth and maintenance and for meeting their energy meets. Filtration - It is a physical process used to separate solids from liquid or gases. Transportation - It is the movement of water and minerals in various parts of the plant body.

Sedimentation is specifically the process where heavy solid particles gradually settle down at the bottom of a liquid due to gravity. Centrifugation uses spinning to force separation, decantation is pouring off liquid after sedimentation, and filtration uses a filter medium - sedimentation is the natural settling process itself.

Amalgamation is the term used when two or more companies liquidate to form a new company.

This is the correct definition for carbonisation.

The rate of energy storage at consumer level is the energy utilized by the consumer for the physiological activities (assimilation).

This method involves the preparation of wastes and decomposing the organic solid wastes by aerobic microorganisms. Waste is prearranged in order to isolate the materials, which can ot be composted so that the degradation process can be done more efficiently. Then these wastes are deposited in machinery in order to produce humus by biological degradation, which contains nitrogen, phosphorus, and potassium. After 3 weeks, the end products are treated mixed with additives and then it is ready for marketing.

This is the correct answer. Plants get rid of gaseous waste products through stomata in leaves and lenticles in stem. They get rid of stored solid and liquid wastes through shedding of leaves, barks and felling of fruits. They also secrete wastes through gums and resins.

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas and heat.

In situ bioremediation method, oxygen is diffused only a few centimetres to 30 cm into the soil to achieve desirable rate of bioremediation.

Ablation refers to the removal of material from a surface through vaporization, chipping, erosion, or melting. In glaciology, it refers to ice loss from a glacier through melting, sublimation, or calving. The term is used in medicine, aerospace, and geology. Sleet is precipitation, cliff is a landform, and pampero is a wind.
