Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment. Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele. Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotype and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity. The greater the genetic diversity within a species, the greater is the chance of that species to survive. Conversely, the lower the genetic diversity within a species, the lower is the chance of survival. This is because unfavorable traits, such as inherited diseases, may become widespread within a population. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution. Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. That is, biodiversity can increase overall ecosystem stability when biodiversity is low, and decrease it when biodiversity is high, or the opposite with a U-shaped relationship.

Biodiversity is essential for maintaining an ecosystem balance, or homeostasis. Biodiversity creates complex food webs that help the ecosystem withstand disruptions, such as natural disasters and man-made problems like deforestation. Biodiversity provides vital ecosystem functions such as soil fertilization, nutrient recycling, pest and disease regulation, and erosion control and crop and tree pollination. Support local and regional projects aimed at tackling biodiversity loss. Buying fewer products and making sure the products you do buy minimize the impact on biodiversity. Investing in ways that promote biodiversity. Reducing waste of consumer goods: food, clothes, electrical appliances, etc. Biodiversity is fundamental to sustaining life, supplying critical ecosystem services such as food provisioning, water purification, flood and drought control, nutrient cycling, and climate regulation. These services are essential to support human well-being and economic growth. If the organisms keep using the present nutrients and resources without filling up the gaps of the used resources, the ecosystem might collapse. So a balance is maintained naturally between the availability and recycling the resources. This balance is known as the Stability of the Ecosystem. Thresholds can be managed by supporting stable ecosystems, which are less prone to collapse. The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem's ability to remain stable when confronted with a disturbance. Through continuous operation of various natural cycles such as the water cycle, carbon cycle, oxygen cycle and nitrogen cycle and it is also maintained due to the existence of various food chains in the ecosystem. A healthy ecosystem is one that is intact in its physical, chemical, and biological components and their interrelationships, such that it is resilient to withstand change and stressors. The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem's ability to remain stable when confronted with a disturbance. Resilience is the speed at which an ecosystem recovers from a disturbance. The most stable ecosystems are found in oceans because it is naturally liquid has dissolved oxygen, is light and temperature sensitive. Other terrestrial ecosystems experience modifications and biotic component succession. Oceans, however, are steady over a very long period of time.

Higher biodiversity leads to a more stable ecosystem. However, there are contradictory opinions on the subject. Different factors may lead to stability loss. The very same factors almost always also cause loss of species diversity. 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. Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of it. The most stable ecosystems are found in oceans because it is naturally liquid (saline), has dissolved oxygen, is light and temperature sensitive. Other terrestrial ecosystems experience modifications and biotic component succession. Oceans, however, are steady over a very long period of time. Ecosystem stability is the ability of an ecosystem to maintain a steady state, even after a stress or disturbance has occurred. In order for an ecosystem to be considered stable, it needs to have mechanisms in place that help it return to its original state after a disturbance occurs. Biodiversity is fundamental to sustaining life, supplying critical ecosystem services such as food provisioning, water purification, flood and drought control, nutrient cycling, and climate regulation. These services are essential to support human well-being and economic growth. Biodiversity boosts ecosystem productivity where each species, no matter how small, all has an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
