Liquid as first of all, the particles aren't compact ( which would mean solid) nor are they spread out ( which would mean gas) nor is it plasma as we aren't given protons or electrons.
In this situation, the rabbit is the primary consumer because it feeds off the producer (grass) and is eaten by the secondary consumer (snake).
Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase
Here is a word equation for the hydrolysis of lactose:
lactose + water → galactose + glucose
Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.
