Biodiversity is essential to an ecosystem's resistance against viruses and famine. In history, there has been many cases in which a lack of biodiversity has allowed a virus or disease to endemically wipe out an entire species of plant. This will subsequently affect all consumers of each trophic level. Ex: A disease that attacks the DNA of only one certain species of plant would cause decreases in the population of the organisms that rely on eating that plant, the organisms that rely on eating those organisms, and so on. This is caused by a decrease in food source, thus not being able to sustain the ecosystem's demand, thus naturally killing off any organisms that would not be able to find a sufficient food source.

A decrease in biodiversity would create an imbalance in the particular type of species present in an ecosystem.

Further Explanation:

An ecosystem is an interconnected system where each and every type of organism depends on the other type of organism for its survival. The decrease in biodiversity means that there is less number of species which is further decreasing in population due to various environmental impacts. The change in one type of organism affects the other type of organism which depends on it for survival. The predators keep the ecosystem in a balanced state but the loss of predators increases the population of preys which affects the stability of ecosystem.

The biodiversity of species is due to evolutionary process where each and every organism contributes or dependent of others.When there is greater biodiversity, changes in one type of organism will not impact the entire ecosystem whereas, less biodiversity affects each and every organism in the food chain.
