Explanation:
A food web shows how organisms in a community prey and feed on each other (feeding relationships). It is composed of many interconnected food chains. In addition, it, therefore, shows how energy is transferred up an ecosystem from the primary producers (in this case the trees and grass) to the tertiary consumers (in this case the hawks and wolves).

the answer is a because if the model is based on experimental data it wont be good unless it has been tested.
It may either be man#1 with blood group b or man#2 with blood group ab
The correct answer is B. Two oppositely-charged ions
Explanation:
In chemistry, ionic bonds only occur between ions oppositely charged, this means one of the ions has to be positively charged and the other has to be negatively charged. This is because there is a natural attraction between particles with different charges and this leads to the formation of chemical bonds. Also, this bond implies the transfer of electrons between ions. In this context, this type of bond can only occur with oppositely-charged ions. Moreover, particles with the same charges either negative, positive, or neutral do not experience attraction and cannot form ionic bonds.
