what is the most largest tropical ocean
Krill are the most largest organism population. Millions of them are in 1 swarm in the ocean.
The largest and most stable ecosystem on Earth is the marine ecosystem, specifically the open ocean. It covers over 70% of the Earth's surface and supports a wide variety of plant and animal life. The open ocean ecosystem is highly diverse and plays a crucial role in regulating the planet's climate and nutrient cycles.
Phytoplankton are the largest group of marine organisms by biomass. These tiny plant-like organisms play a crucial role in the marine food web as they are the primary producers, converting sunlight into energy through photosynthesis. Their abundance and distribution support a wide variety of marine life, from zooplankton to large marine mammals.
The Amazon River watershed contains the greatest variety of organisms on land.In the ocean the top layer has the greatest variety, because it is closest to the sunlight.
It is Pacific ocean. Fairly because it is largest and being its mostly area on tropic it supports bio diversity.
Most plants and animals live in the Sunlit Zone.
