Abiotic and biotic factors work together to keep an ecosystem balanced. When an invasive species like the crown-of-thorns starfish enters the Caribbean reefs, coral cover and the total number of fish species decrease a few years after the invasive species enters the ecosystems. The reduction or removal of herbivorous fish due to overfishing creates an increase in the algae population which in turn reduces the coral population and harms the rest of these ecosystems.

As carbon dioxide concentrations in Earth's atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. Agriculture can have serious negative environmental effects, such as soil, water, and air pollution, but it can also have positive effects, such as capturing greenhouse gases in crops and soils or reducing flood risks by using specific farming techniques. Humans are the biggest threat to the integrity of a coral reef. Think of it as a domino effect; if one-piece falls (the abiotic factor), the rest of the dominos will fall too (the ecosystem).
