Why Biodiversity Is Important Essay

Why is biodiversity important to an ecosystem? Why is it so important that we have different species of animals living together? It is extremely important for different species to be living together, because they all rely on one another for survival. Including us humans, we rely on other species to survive. We don’t just rely on other species for survival, but evolution has driven us to evolve to adapt and live longer.

In an ecosystem, there are habitats. In a habitat, there are populations and communities. Every different animal has different niches in their native area. A niche is the job of that specific organism. A habitat is where a group of organisms live. A population is a group of animals that are all the same species. A community is the total amount of …show more content…
They will often compete for the food. If one of the predators died out, the population of the other predator would grow because they would be able to obtain more food easily without any competition. The prey’s population would also grow because of losing a natural predator. Meaning that the birth to death ratio would change. There would be more births per deaths. Sometimes, organisms might rely on other organisms for protection. If biodiversity didn't exist, then everything would eventually die out in a short time.

It’s also very important that animals evolve to survive. Animals can evolve to survive by adapting to their environment or by evolving to attract mates. Some animals like peacocks evolve to look more and more stunning, to attract a mate. Some animals will test their different mates before choosing the right one, this is usually a physical test like a race. Animals can also adapt to become more capable. Some animals like ducks have evolved to prevent rape from male ducks. But over time, the male ducks have also adapted with their genitalia, it has adapted so that it can fit inside the females
