Conventional agriculture is a type of farming that relies on synthetic chemical fertilizers, pesticides, and herbicides to maximize crop yields.
What is agriculture?
Agriculture is the science, art, and business of cultivating plants and livestock. It involves the cultivation of soil, crops, and livestock, as well as the processing and marketing of food, fiber, feed, and other agricultural products. Agriculture has been a major source of income for people throughout history and continues to be the basis of many economies today.
Conventional agriculture typically relies on monoculture, or the growing of a single crop over a large area, as well as large-scale mechanization to increase efficiency. Conventional agriculture is often contrasted against organic or sustainable agriculture, which utilizes natural methods and materials to maintain soil fertility and protect the environment.

What is an organism that obtains energy by feeding on other organisms called?
An organism that obtains energy by feeding on other organisms is called a consumer or a heterotroph. Consumers are organisms that cannot produce their own food and must consume other organisms to obtain energy. This can include animals that eat plants or other animals, as well as decomposers such as bacteria and fungi that break down dead organic matter.
There are different types of consumers, depending on their feeding habits, for example:
- Herbivores: consumers that feed on plants
- Carnivores: consumers that feed on other animals
- Omnivores: consumers that feed on both plants and animals
- Scavengers: consumers that feed on dead organisms
- Decomposers: organisms that feed on dead organisms and break down organic matter.

How might the destruction of rainforest affect the balance of gases in Earth's atmosphere by increasing carbon dioxide and decreasing oxygen?
Trees take in carbon dioxide and traps it into tissues and soil while at the same time releasing oxygen into the atmosphere. The removal of trees significantly reduces the rate of this process, resulting in higher carbon dioxide in the atmosphere and lower natural oxygen levels.
Definition of Rain ForestRain forest is a type of forest that grows in the tropics. As the name implies, this forest which has the nickname wet forest is never absent from rain. In other words, it is a forest that has a high rainfall intensity.
This forest has a long rainy season, with up to 1,200 millimeters of rain per year. The existence of this high rainfall, causing the dry season in forest areas to be very short. In some places, there is no dry season at all.
The average rain that falls in this area is around 50 to 250 inches each year. Air humidity in this forest area which is always wet averages 77% to 88%.
In warmer years, the forest areas rarely get above 33 degrees. The temperature is generally below 20 degrees Celsius.
Just like primary forest, rainforest is a forest that has fertile soil. This forest has a layer of humus that is formed from green leaves that decay on the ground surface.
Therefore, it is not surprising that scientists claim that because of the fertility of the soil, this forest is inhabited by more than half of the plant and animal species on earth.

Black coat is dominant over white coat in guinea pigs. a homozygous black pig is mated with another homozygous black pig.-What are the genotypes of the parents?-What are the phenotypes?-what is the probability that white offspring will be produced?
The genotypes of the parents in this scenario are both homozygous dominant for the black coat color allele (B) and the probability that white offspring will be produced is 0%
How genotypes of the given parent pigs are defined based on the observation?Each parent has two copies of the dominant B allele, which codes for a black coat color, and no copies of the recessive allele (b) that codes for a white coat color. Therefore, their genotype is BB.
What are the phenotypes of the given parent pigs?The phenotypes of the parents are both black, as the dominant B allele masks the effect of the recessive b allele. This means that the physical appearance of the parents is black, as the black coat color is determined by the dominant B allele.
What was the probability of white offspring produced after mating?When two homozygous dominant black guinea pigs are mated, all of the offspring will be homozygous dominant for black coat color (BB), as both parents only have the dominant B allele to pass on. Therefore, the probability that white offspring will be produced is 0%. This is because the recessive allele for white coat color (b) is not present in the genotype of either parent, so it cannot be passed on to the offspring. In such a case, all the offspring will have black coat.

Changing the temperature or pH can change an enzyme' hape. Explain how changing the temperature or pH might affect the function of an enzyme
Due to the fact that enzymes are made up of functionally-group-containing amino acid chains, the pH of a solution might have an effect on the enzyme.
By raising the bond energy, temperature impacts enzymes by forcing the atoms in the enzyme's bonds to drift apart from one another.
These functional groups are susceptible to adjustments caused by external charges. Each enzyme operates within a rather narrow pH range. There is a pH where it is most active (the optimal pH). This is due to the fact that pH variations can create and destroy intra- and intermolecular interactions, altering the structure of the enzyme and its functionality.
When certain circumstances are met, enzymes work at their best. pH, enzyme concentration, and substrate concentration are variables that influence enzyme activity. Enzyme activity is affected by temperature.
