Biochemists are

scientists who study the chemical and physical principles of living organisms and biological processes, such as cell development, growth, and disease.

organisms that lives in saltwater environments like estuaries and coastal wetlands to understand underwater

sea life like their health,behavior and how sea life acts in their ecosystems.They often communicate their research findings to the public and policymakers to raise awareness about marine conservation and issues like climate change and overfishing they may advise on projects and policies to minimize negative impacts on marine habitats. A bachelor's degree in marine biology or a related field like marine science is typically required for entry-level positions, while a master's or doctoral (Ph.D.) degree is generally needed for independent research and advanced.Marine biologists help the world by studying and protecting ocean ecosystems and the life within them, ensuring sustainable fisheries, developing conservation strategies for marine habitats, understanding the effects of climate change and pollution, and educating the public and policymakers on ocean health issues. Their work identifies problems, proposes solutions, and influences policies to maintain healthy oceans that are vital for the planet's well-being and human prosperity. SUMMARY:A marine biologist is a scientist who studies, watches and saves underwater life from tiny plankton to large whales and protecting them and their habitats from threats like pollution and human activity.
