Global Water Environment

An ecological pyramid indicates energy passing along from autotrophic organisms to carnivores at the top of the chain – and it includes the global water environment. Those at the bottom of the food chain are usually the smallest in size but not always, and are almost inevitably the largest in number. Those who feed off these primary producers are less in number, usually because they are larger and require more than one portion of prey per meal as a means of fulfilling nutritional requirements for a larger organism. The global water environment provides the basis for development. This situation continues to the top of the chain, where few secondary consumers are eaten by an even smaller amount of tertiary consumers. This is typical of a food chain in a global water environment community.
