Both show different examples of food chains.
In the coral reefs, there are many different food chains. The general labels are producer and consumer; from there the labels get into more depth. Producers are autotrophs since they use photosynthesis to get their food. There are two types of consumers: herbivores and carnivores. Herbivores consumers eat plants only while carnivores consumers are heterotrophs because they eat other organisms to get their nutrients. Each community's food chain are interconnected by the way they affect each other. A specie can dramatically change the food chain by the population and what eats them and who do they eat. Population and competition can effect each other very much. The size of a population can determine how much competition there is between two species that share a food supply. When two species are in a symbiotic relationships, one of the organism relies on the other to live or for food. In these relationships, it could be beneficially or harmful to the one or two of the organisms.
