Many farmers in less densely populated area, such as Amazonia, practice slash and burn agriculture, also known as shifting cultivation or swidden agriculture where an area is cleared and then burned for the vegetative remains to release nutrients back into the soil. Shifting cultivation is a system where a farmer uses a piece of land, only to abandon or alter the initial use a short time later. Advantages of shifting cultivation includes; enhance control of pest and disease, inorganic matter addition which provide nutrient to crop, an effective way of weed control
The style is the female reproductive part of the plant. it plays important role in plant breeding .
What is style and the role of style in reproduction ?
The stigma and ovary are connected by a long tube-like structure called the style. The pollen tubes bearing male gametes enter the style tissues and travel to the ovary's ovule once the stigma's pollen grains have germinated. Once within the embryo sac, it travels to the egg cell to fertilize it with the aid of the filiform apparatus.
The style is crucial to the plant reproduction process since it not only serves as the site for the formation of the pollen tube but also functions to prevent incompatible pollen from entering the ovary. Genetic information is transferred between the pollen and the plant when the pollen tube begins to spread within the style. The plant also produces a poison at this period. The plant will release the poison to block the formation of the pollen tube if the pollen is unsuitable because it comes from a different species or is too closely related, leading to inbreeding.
If the pollen is compatible, the plant will isolate the poison and sequester it so that the pollen tube growth is not halted. Therefore, the style is the area where compatibility is evaluated and where it is decided if pollen that falls on a flower will be allowed to fertilize the plant.

B! we had to alter them to our preferred taste and nutrients
Answer:
Plants take in carbon dioxide from the environment for photosynthesis. Because trees are large, they need a lot of energy, which likely results in a lot of carbon dioxide being removed from the air. If they’re chopped down, there will be fewer trees to remove the extra carbon dioxide from the air.
Explanation:
answer from Plato
The units of genetic distance derived from bacterial conjugation studies are called minutes. Bacterial conjugation is the process by which a bacterium transfers genetic materials to another through direct contact. One bacterium serves as a donor of the genetic material and the other serves as the recipient.
