Marine biology is the scientific study of organisms that live in saltwater environments. This field encompasses various aspects of marine life, including the behavior, physiology, and ecological interactions of marine organisms, as well as the impact of human activities on marine ecosystems.

Topics to Cover in Marine Biology:

Marine Ecosystems: Explore the different marine habitats such as coral reefs, estuaries, and deep-sea environments. Understand the unique characteristics and organisms found in each ecosystem.
Marine Organisms: Study the diverse range of marine organisms including phytoplankton, zooplankton, algae, seaweeds, invertebrates, fish, marine reptiles, and marine mammals.
Marine Food Chains and Webs: Investigate the interconnected relationships between marine organisms and the flow of energy through marine ecosystems.
Marine Conservation: Discuss the importance of preserving marine biodiversity and understanding the impacts of pollution, overfishing, and climate change on marine ecosystems.
Marine Biotechnology: Explore the potential applications of marine organisms in fields such as medicine, industry, and environmental remediation.
