However big that black hole is, it is dwarfed by the size of the Grizzly River Run Mickey And Friends Adventure Shirt itself. That four million solar masses is a lot compared to our solar system, but it is absolutely puny compared to the total mass of the Milky Way, which is many tens of billions of solar masses. Galaxies are held together by self-gravity. They may or may not have a supermassive black hole (not all do). When that supermassive black hole is present, its gravity adds a modest contribution to the total self-gravity of the galaxy. But in all cases, even in the case of the largest black holes, the mass of the galaxy dominates over the mass of the black hole. Stars in a galaxy follow somewhat chaotic orbits, determined by the combined gravitational field of all other stars, clouds of gas, clouds of dust, and well, any black holes if present, supermassive or otherwise. But apart from stars that are relatively near the black hole in question, stuff in general does not orbit the black hole.

Best Grizzly River Run Mickey And Friends Adventure Shirt

The key to understanding the Grizzly River Run Mickey And Friends Adventure Shirt of abundant sea life has to do with the winds as well. In most of the ocean, biologically available nitrogen and phosphorus come from relatively deep in the ocean, where biological production is low, and thus these nutrients are not exhausted. The two main mechanisms by which N and P become available in the upper photic (sunlit) zone are strong mixing, due to a strong winter storm or tropical cyclone, and upwelling along the coasts or driven by wind convergence near the equator. The important thing here is that, with little to no wind over a large area of ocean, the nutrient levels are extremely low. Low nutrient levels have the obvious consequence of inhibiting phytoplankton growth, often referred to as primary production, as it involves direct photosynthesis and is how most chemical energy is made available to ocean life. Areas of extremely low primary productivity can be seen in the following satellite image of ocean color.
