The collision theory in chemistry is used for the prediction of the rates of the chemical reactions, it is mainly used for the calculation of the rate of the chemical reactions occurring in the gaseous state.
The main assumption of this theory is reacting substance (atom or molecule) must come and collide to react and form a product. It was proposed by Max Trautz in the year 1916.

Answer: a. the lowest trophic level

The members of the keystone species are abundantly available at the lowest trophic level. This will help in making a balance in a community or ecosystem. If some members die others will be available to survive others.
