Why is it important for there to be different species in an ecosystem? What would happen if all the species were the same? Expla
irina [24]

Answer: Biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines. If all animals in an ecosystem were of the same species, the balance would be lost.

Explanation:

An ecosystem is a set of living beings (of different species) that share the same habitat or biotope. There are first of all primary producers, those that are capable of producing organic matter from inorganic compounds. These organisms are autotrophs, such as plants. Then we find in the second step the consumers, heterotrophic organisms (herbivores, carnivores or omnivores) that feed on matter and energy produced by other living beings. And in the last link of the trophic chain of organisms that make up an ecosystem we find the decomposers, those that feed on dead organic matter. In this way, there are complex interactions between different organisms of different species.

<u>Thus, biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines.</u>

If all animals in an ecosystem were of the same species, the balance described above would be lost. If they were all producers like plants, there would be no consumers to control the plant population. If they were all consumers, they would eventually run out of food. And if they were all decomposers, they would not have enough dead organic matter to feed on either.  A greater number of species or biological diversity in an ecosystem makes it more resilient. <u>Because species can absorb and reduce the effects of environmental changes on the overall structure of the ecosystem</u>. In addition, they can reduce the chances of a change to a different state.
