​​​​​​. Differences between gram positive and gram negative

Gram-positive bacteria gives a positive result on Gram staining due to the characteristics thich layer of peptidoglycan in cell walls. And Gram-negative bacteria gives negative results due to presence of thin layer of peptidoglycan in cell walls.

​​​​​. Describe the importance of metabolic diversity for the environment, including discussing the production of oxygen and food and nutrients and nitrogen fixation.

Metabolic diversity is the life's evolutive response that enables it to adapt and use all available form of energy and organic and inorganic matter sources.

Oxygen is essential for almost all life foams except anambi organisms Canobacteria, Phytoplanktons boues, shoubs, grasses and other plants poodies energy and release oxygen. Oxygen is available in East as a sesult of green plants and pookaryotic autophics produces -oxygen. Oxygen is the byproduct of photosynthesis. At the same of oxygen podructe produced for whole world. also

The Earth's food are supplied directly or indirectly by dants ovien plants poodine food in the form af caskeky doates, proteins etc. And the amals use this energy from to meet their molabolie actinities Plants requiries nutrients for goowth. After death they contribute recycling of nutrients. Nutrients are transfered from plants to animals. Nitrogen fixation is mainly accombined by plants and bacteria. Nifoogen fixation is very important So, as to plants inosder to absorb nitrogen Plantes can't bin nitrogen itself but are fixed by some associated bacteria. The pookaryotes show greates metabolic diversity than enkasyoles • Metabolic diversity involves different metaboli strategies that organisms have evolved to obtain energy. Some use oxygen, some use food to oblain energy.

. What is bioremediation?

Piosemediahon is the love of this natuwally ownina of the introduction of microorganisms to consume and break down environmental pollutants on Waste into nutrients and organic matter but it cannot desbay 100% contaminants. In this process, biological organisms to solve an environmenfal problem such as contaminated galos ground water. For this, bacteria, kungis protists and other misobes are used. 0
