The first trophic level of a food chain or web is reserved for plants and other photosynthetic organisms that captures solar energy from the sun and converts it to chemical energy. The second trophic level is reserved for herbivores or primary consumers. The third trophic level or secondary consumers are carnivores or predators.
Decomposers are not usually drawn or represented in a food web or chain but they do play a vital role. Decomposers break down dead and decaying organisms and return these unused nutrients to the soil for producers to use.
The pH will decrease because lemon juice is very acidic meaning it would bring the pH level down to a more acidic value.
