Plant and animal cells both undergo mitotic cell divisions. Their main difference is how they form the daughter cells during cytokinesis. During that stage, animal cells form furrow or cleavage that gives way to formation of daughter cells. Due to the existence of the rigid cell wall, plant cells don't form furrows

This question requires more information for a complete answer. 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.
