All except number 2. Hope this helps!
Since they are now able to genetically isolate favorable traits they can "clone" prize-winning livestock and make the production as efficient as possible
The pyramid of biomass represents a range of food webs found in one trophic level
A pyramid of biomass refers to graphical representation of biomass that is present per unit area of all the various trophic levels of the ecosystem.
<h2>Further Explanation</h2>
The graphical representation shows the relationship between biomass and trophic level that quantify the biomass that is present in each trophic level of energy community at a given period of time.
There are two types of pyramid of biomass, they include
- Inverted pyramid of biomass
- The upright pyramid of biomass
Inverted pyramid of biomass: a very good example of inverted pyramid can be seen in a case of pond ecosystem, where major producers in the ecosystem (mass of phytoplankton) will be lower than the mass of heterotrophs, such as insects.
The upright pyramid: The first thing on the upright pyramid is the producers, such as plants. The plants are present at the bottom level of the pyramid and followed by consumers.
Within the pyramid, the highest level is occupied by the carnivores; they are the lowest quantified amount of biomass. In upright pyramid the total weight of the producers is far more than when the weights of all the consumers are combined.
However, the main issues with the pyramid of biomass are that every trophic level of the pyramid seems to have more energy than it does.

Answer: D. Acid from abandoned mines
Explanation:
Point source pollution can be define as the pollution that can be caused by a pollutant whose source of origin is known. As the source of origin is known the path of the pollutant can be traced back to it's origin hence, the pollution can be controlled.
Among the options given, D. Acid from abandoned mines. is the correct option this is because of the fact that the source of origin of the pollutant is known that is abandoned mines.
