Ecologists use food web diagrams as tools in their studies of different populations of organisms within an ecosystem because it shows the feeding relationship between organisms in the ecosystem.
<h3>What is a Food web?</h3>
This is defined as the graphical representation of the feeding relationship which occurs between organisms in the ecosystem and helps to predict the outcome in the addition or removal of a species.
The food web also helps to determine the various ways in which energy flows and it usually starts from the producers which are the plants as a result of their photosynthetic ability which involves the conversion of solar energy to chemical energy.
There are various organisms in the ecosystem and the food web helps to provide a better understanding of their feeding habits and impact various factors will result in.

Answer:
Water is added to a concentrated solution of sodium thiosulfate to dilute it.
Explanation: Water is a universal solvent. It has the capability to dissolve many substances in it. When water is added to a solution, the concentrated solution can be diluted. Dilute solution means the presence of water in high amount and solute quantity is very low.
Answer:
Explanation:
Since the crystal structure is FCC , every unit cell will have 4 atoms . If a be the edge length
average density = 4 x average atomic no / volume of unit cell x N
N is avogadro no or 6.02 x 10²³
average atomic no
= 100 / (87/107.9 +13/106.4) = 107.72
average density = 100 / (87/10.49 + 13/12.02)
= 10.667
10.667 = (4 x 107.72 )/ (a³x 6.02 x 10²³)
a³ = 4 x 107.72 / (10.667 x 6.02 x 10²³)
= 6.71 x 10⁻²³
a = 4.063 x 10⁻⁸ m
