Answer:
The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.Inorganic Contaminants and Wastes
Inorganic Contaminants and WastesInorganic compounds may consist of heavy metals and toxic elements (e.g., lead, mercury, chromium, arsenic, etc.) in pure form or combined with other elements. These compounds exist primarily in the solid phase, but can also exist at ambient temperatures in the gas phase if finely divided or have a high vapor pressure (e.g., mercury, hydrogen sulfide) or the liquid phase if water soluble. In general the undesirable (e.g., toxic or hazardous) nature of these compounds stems from the element(s) they contain rather than their structure. Therefore, the undesirable in most inorganic compounds cannot be eliminated by oxidation or thermal decomposition of those compounds. Notable exceptions include compounds such as hydrogen sulfide (H2S) and ammonia (NH3), which when oxidized become far less toxic.
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities
