Ocean Ecosystems
A biodiverse reef in the Red Sea. Biodiversity in marine ecosystems is essential for maintaining ecosystem stability, resilience, and the overall health of the ocean, supporting a wide range of species and ecological processes.
Investigating Ocean Ecosystems will help you to:
- understand the three main ocean zones (intertidal, pelagic, and benthic zones).
- describe the habitats found throughout the ocean.
ABOUT THE AUTHOR
Catherine “Cathy” Christopher has always been passionate about science, with a special love for marine biology.. While she once dreamed of studying whales, her fascination quickly shifted to the incredible world of invertebrates during her undergraduate studies at Bowling Green State University. She later earned her Master’s in Biology from Florida Atlantic University, where she also became scuba certified and gained hands-on experience with sea turtles, birds, and everything in between.
Cathy’s career has spanned from developing engaging K-12 science curricula to leading educational initiatives that make marine science accessible to learners of all ages. When she’s not crafting the next great science lesson, Cathy can be found underwater, exploring reefs across the Caribbean and Indo-Pacific. A certified dive instructor since 2017, she loves pointing out unique marine invertebrates and is always happy to help fellow divers identify their latest underwater finds.
