Food webs and the carbon cycle are closely related because all living organisms are composed of carbon. He protects the larvae post-hatching until they reach their juvenile stage and leave the nest, about 45 days after fertilization. The fishs color helps it blend into the muddier sediments along which it lives, and its photophores help it attract prey while the midshipman stays almost completely still.
