Answer: Natural Selection is the (natural) process in nature whereby organisms (plants, animals, etc.) that are better adapted to survive and thrive in their environment, are more likely to survive in order to breed/reproduce and pass on their own genes and characteristics. These characteristics can be physical or behavioral.
Artificial selection is where man, instead of nature, determines which characteristics they would like to hone. In the case of crops, edible, tasty, easy to cultivate crops were chosen above harder to grow crops. Animals kept for meat and other products, were selected based on how much milk, wool, meat, etc. could be produced. Health was also a factor, as sickly animals are troublesome (and potentially unsafe to utilize their products). In the case of domesticated pets, let us consider the dog, originating from domesticated wolves. The more easily trained, protective, better natured wolves were chosen to continue to line of species and the undesirables discarded.

Answer:
New species develop when:
D. Diverging species no longer recognize one another as potential mates.
Explanation:
- The development of two or more new species from ancestral population is known as speciation.
- Speciation can occur when the population divides into groups and each group occupies a different habitat (geographic isolation) or when the members of the same population do not find one another as potential mate and do not interbreed (reproductive isolation mechanism).
- The three types are: Allopatric speciation.
Sympatric speciation.
Parapatric speciation.
- Allopatric speciation occurs when genetic divergence is allowed through geographic isolation.
- Sympatric speciation does not involve geographic isolation but involves reproductive isolation mechanisms.
- In Parapatric speciation, a population enters a new niche or habitat within the range of parent species and then evolution of reproductive isolation mechanism occurs.

Answer:
Population- This is why we refer to the amount of people in an area as the area's population
Answer:
Its speed is determined by three major factors: soil organisms, the physical environment and the quality of the organic matter (Brussaard, 1994). In the decomposition process, different products are released: carbon dioxide (CO2), energy, water, plant nutrients and resynthesized organic carbon compounds.
