By analyzing how many individuals of that species exist in a certain region, you can determine how dense that population is. This is calculated by accounting for the number of each species within a given area. It similarly can cause harm to animals in that system.īiodiversity is generally measured in terms of density or richness. A change in climate can affect the growth of plants, increasing some or decreasing the likelihood of survival for others. If all the wolves in the system get sick and many die off, there will be an increase in rabbit population, which will then mean certain vegetation will be decimated. For example, disease may affect one particular species in an ecosystem and throw off the balance in that area. These factors can be affected naturally, or by human influence. They are: a change in habitat, a change in the climate, and a decrease or influx of any one species. There are three main factors which can affect biodiversity. Diversity helps maintain balance and prevent against harm. When an ecosystem is not diverse, meaning there are very few different plants, animals or bacteria within that system, one change, or removal of any given part, can spell disaster and a complete collapse of the system. There are multiple examples within any region of each category of insect, bacteria, herbivore, omnivore or carnivorous predator. Diversity is essential to the smooth running of any ecosystem.
