Under the broadest definition of the term, marine resources are the things that plants, animals and humans need for life that originate in the ocean. Different organisms derive different resources from the marine biome. Most organisms that require marine resources for survival live inside the marine ecosystem. However, some birds and land mammals also derive food from the ocean.
The primary resource humans derive from the environment is food. Humans have caught fish from the world’s oceans for millennia, and the marine biome provides a bounty of high-protein food sources. Fish like halibut, sea bass and salmon are important for human diets, but humans also eat shrimp, crabs, squid and lobsters. Additionally, humans harvest kelp and minerals from the marine ecosystem, which are useful in a number of applications. Humans also use the marine biome for recreational purposes, such as skiing, swimming and boating.
The fish, sharks and invertebrates living in the ocean get all of their resources from the marine biome. For instance, a crab may eat a dead fish for sustenance, get oxygen directly from the water and take shelter under a large rock. The plants growing in the ocean, such as plankton, algae and seaweed, derive their mineral requirements directly from the water.
