Is citric acid a natural or synthetic?
Citric acid can be both natural and synthetic. It can be derived from natural sources such as citrus fruits like lemons and oranges. However, it is also commercially produced through fermentation of sugars by certain microorganisms, resulting in a synthetic version of citric acid.
What is a synthetic resource?
Synthetic resources are man-made resources, made from natural resources, or resources that come from nature.
The sources of increased nitrogen levels on agricultural land?
There are several sources of increased nitrogen levels on agricultural land. These include the application of synthetic fertilizers, animal manure and urine, as well as nitrogen-fixing crops like legumes. Runoff from livestock operations and the use of nitrogen-based pesticides can also contribute to elevated nitrogen levels in agricultural soil. Additionally, atmospheric deposition from industrial activities and automobile emissions can deposit nitrogen onto farm fields.
How does using the synthetic fibers and plastics help to conserve natural resources?
Most synthetic fibers are made from petroleum(oil)... a resource that is not replacable. Making synthetics takes energy and chemicals to process, creates waste that is relatively hazardous to plant and animals , and adds to the carbon emitted into the air. The oil industry is selling the world on Fracking for natural gas and Tar Sands ,processing as new sources of energy and petroleum for the chemical industry, but , so far these processes seem very dirty and destructive to water and air. It is generally considered that natural fibers like cotton, flax and hemp are much more sustainable; ie they can be grown with minimal use of chemical fertilizers or pesticides and feel more comfortable for clothes , linens, and furniture. there are many synthetic fibers, however, that wear longer, are stronger, resist water and heat and wont replace synthetics. But , once again, all synthetics use oil or other fossil fuel as a major ingredient. It's hard to see any way that this "conserves" natural resources.
What is synthetic reactions?
Not natural or genuine; artificial or contrived. It's something that has not been brought on by natural events. Sort of like synthetic leather.
What are some major sources of pesticides?
chemical warfare developers
Organically grown means the food is?
"Organically grown" food is food grown and processed using no synthetic fertilizers or pesticides. Pesticides derived from natural sources (e.g., biological pesticides) may be used in producing organically grown food. The exact definition of what may be deemed "organic" differs between different countries and also for specific food types. Usually before farmers can claim to be producing organic food they need to register and gain approval from the relevant governing body.
What is the main sources of water pollution?
The main sources of water pollution are as follows : 1) sewage 2) Industrial wastes 3) synthetic soaps and detergents 4) fertilizers and pesticides 5) petroleum 6)Heat.
What are the main threats for bald eagles survival?

How do synthetic pesticides kill bugs?
Disruption of life-sustaining activities ultimately is the way in which synthetic pesticides kill bugs. The pest-killers most effectively realize this end through making the bug's food sources, resting places, and transportation routes toxic. Depending upon the laboratory-made active ingredient in question, the above-mentioned interaction will affect -- with crippling, terminal consequences -- a key life-sustaining body part or process of the bugs in question.
What organisms will be affected if small insects and crickets and earthworms are killed by pesticides?
Robins are the organisms that would be most affected if pesticides killed crickets, earthworms and small insects. These are the robins' only food sources, so the robins' survival depends on their abundance.
Can pest aside cause pollution?
There are thousands of types of Pesticides, some of organic and natural sources and some synthesized chemicals like paralytics. The word pollution could be subjective, Atmospheric Pollution - Possibly through pesticides delivery system, CFCs Water System Pollution - Possibly, in the case of DDT and birds for example Soil Pollution - Possibly, in the case of chemicals that are not soluble
What external sources can cause non-Hodgkin's lymphomas?
People exposed to certain pesticides and ionizing radiation have a higher than average chance of developing this disease.
What is the definition of natural substances?
Natural Substances are those which are prepared from herbs and minerals, not from chemical or synthetic sources.
Identify three sources of drugs and a drug that is still used today that comes from each source?
natural sources semisynthetic and synthetic
How do the pesticide levels in greenhouse grown produce compare to the pesticide levels in conventional or organic produce?
Organically grown producetheoretically has lower pesticide levels than those grown conventionally or in greenhouses.Specifically, organic agriculture and gardening adheres to non-chemical means to prevent or treat pests and problems. The use of pesticides is an option which is considered after examining the challenge from the perspective of biological, cultural and mechanical controls. The pesticide which will be chosen will be made from such naturally occurring sources as plant body parts. As a natural, non-chemical, non-synthetic pesticide, it will be checked against the harmful possibilities of affecting non-target entities, poisoning living organisms, and remaining in the environment.In contrast, conventionally grown produce generally involves as the first option the use of chemical, non-organic, synthetic pesticides. Such pesticides may be effective in controlling pests and problems. But they also may harm unintended targets and persist in organisms, produce, soil and water.Theoretically, greenhouse-grown produce can be expected to be pesticide-free. The greenhouse functions as a controlled environment in which natural enemies generally are not expected to be present. But perpetually humid, warm environments may contribute to other pests and problems. As a result, pesticides may be applied, and the controls may have a greater likelihood of being non-organic instead of organic.
