Describe somerelaionsips and interaction that occur among biotic components in ocean?

In ocean ecosystems, biotic components such as phytoplankton, zooplankton, fish, and marine mammals interact in complex relationships. Phytoplankton, which are primary producers, convert sunlight into energy through photosynthesis, forming the base of the food web. Zooplankton feed on phytoplankton, while small fish consume zooplankton. Larger fish and marine mammals, such as whales, prey on these smaller fish, creating a dynamic network of predator-prey interactions that maintain the balance of marine ecosystems.
