Answer:
Ecosystem services.
Explanation:
Essential services, such as water purification, nutrient cycling, and plant pollination are all examples of Earth's ecosystem services.
An ecosystem can be defined as the natural living habitats of both living and non-living organisms.
Hence, this essential services that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.

Arrow A represents the direction of the electric field vector at the position of the dot.
A dot indicates the location of an electric charge at a certain location. The electric field line will radiate outward in the case of a positive charge. If the charge is negative, the electric field will radiate outward from it. The direction of the electric field at a certain location is not, however, shown by the dot. As a result, reading the values of negative signs on a field line is useless.
As compared to the negative charge, the positive charge, Q, is twice as distant from the dot. We must first measure the intensity of the electric fields in order to determine the electrical field at a certain location. The positive charge is represented by +Q in Figure Q20.5, whereas the negative charge is represented by -1. The intensity of the electric field at a spot represented by a dot must thus be equal to the total of the electric fields pointing in that direction.
