Answers
Answer:
1.Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.
5.Polyblend is a fine powder of recycled modified plastic. This mixture is mixed with the bitumen that is used to lay roads. It enhances the bitumen's water repellant properties, and helped to increase road life by a factor of three.
Answer:
I'll answer a few to the best of my ability!
Explanation:
1. the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.
2.Due to these many uses, they enter the surrounding areas of land and water, and therefore have a wide effect. The use of water makes it possible to grow fruit and vegetables and to raise livestock, which is an important part of our food. Therefore, agrochemicals enriched the crop production.
4.Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades, or even millions of years after a mass extinction.
5. Polyblend is the material formed from a mixture of two or more polymers, especially of man-made fibres or recycled plastic. It is also a colloidal mixture of one polymer with another. (example a mixture of vinyl resin with nitrile rubber).
