Increased biodiversity can lead to greater stability of the marine ecosystem and the biotic factors needed for it to become self-sustaining. Biodiversity plays an essential role in maintaining ecological balance. Several studies have demonstrated that marine species diversity contributes to ecosystem stability.

Firstly, a greater diversity of marine species ensures better use of available resources. Each species has specific characteristics that enable it to adapt to a particular environment. Greater diversity ensures more efficient use of food resources and reduces competition between species. This helps to maintain population equilibrium and avoid major fluctuations.

Secondly, an increase in marine biodiversity promotes ecosystem resilience in the face of external disturbances. Ecosystems with greater diversity generally have a greater capacity to resist and recover from events such as storms, disease or climate change. When species diversity is high, there is a greater chance that at least some species will resist these disturbances, thus limiting negative impacts on the ecosystem.

Finally, marine biodiversity contributes to the regulation of biogeochemical cycles, such as the nitrogen and carbon cycles, which are essential to the overall health of the ecosystem. When different species interact with each other, they can help maintain these cycles by balancing nutrient flows and reducing the excessive burning of certain key elements for marine life.

However, it should be noted that an excessive increase in biodiversity can also create challenges for the stability of the marine ecosystem and the achievement of complete self-sufficiency.

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. As, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change. Ecosystem stability is an ecosystem's ability to recover from a disaster. Imagine that a disaster wipes out a species. If the ecosystem has high biodiversity, a new species will quickly move into the niche occupied by the old species, and the ecosystem as a whole will recover quickly. An increase in the biodiversity of an ecosystem leads to an increase in its productivity. Macroevolution occurs within a population.Biodiversity is of critical importance to the stability of natural ecosystems and their abilities to provide positive benefits such as oxygen production, soil genesis, and water detoxification to plant and animal communities, as well as to human society. As a general rule, increasing biodiversity can be achieved by diversifying the range of habitats or vegetation structures available at a site. This can be achieved by, for example, varying mowing regimes, planting or seeding with native tree and shrub species, or occasional soil disturbance. Ecosystem stability is the ability of an ecosystem to maintain a steady state, even after a stress or disturbance has occurred. Biodiversity is essential for stability of an ecosystem. Communities having more species tend to be more stable than those with less species. A stable ecosystem is able to resist occasional disturbance. An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem. Many abiotic factors nonliving physical and chemical aspects of an environment, such as sunlight levels, soil chemistry, and climate shape healthy ecosystems. There is a variety of abiotic factors that influence aquatic ecosystems. These factors include temperature, depth, rate of water flow, the availability of sunlight, salinity (or saltiness), and the acidity of the water.
