Nitrogen fixation can become greener if the natural chemicals are used in the plants.
Phytochemicals are the natural chemicals in plants. Only a few of these chemicals have been linked to improved health--like beta-carotene, lycopene, and salicine (which became aspirin)--but eating vegetables is a wise choice to improve nutrition and digestive function.
Yes, and also from the natural breakdown of plants and animals. Plants and animals break down into nutrients (chemicals) which plants can use to produce new growth.
Some chemicals make plants grow. They are called fertilizers. Some chemicals plants make plants die. When intentionally applied, they are the type of pesticide called herbicides. Some chemicals do not affect plants.
No. Synthetic chemicals are indistinguishable in every way from natural chemicals.
The classification of natural substances, such as plants and herbs, is not typically included in the Table of Drugs and Chemicals. The Table mainly focuses on synthetic drugs and chemicals, including pharmaceuticals and illicit substances.
Chemicals are natural or artificial.
Is chemicals from plants chemical weathering or physical weathering
Well the first medicines were just herbs and natural plants which were evventualy mixed together in different ways so they could fo things differently or just so it was more efficient. Later we figured out what chemicals were in these natural medicines and now we make medicines with mixes of those chemicals and other chemicals.
Pesticides can be made from synthetic chemicals, natural products, or a combination of both. Common synthetic pesticides are derived from chemicals like organophosphates, carbamates, and pyrethroids, while natural pesticides can be sourced from plants (e.g., neem oil) or microbes (e.g., Bacillus thuringiensis).
The term for this study is natural products chemistry. It involves the extraction, isolation, and characterization of bioactive compounds from plants and animals for various applications in medicine, agriculture, and industry.
