Why should we protect an entire ecosystem and not just one species?

Because every species in an ecosystem has a part to play, and if you take away one species it unbalances the whole ecosystem. This can lead to over population and a scarcity of food. This is why ecosystems as a whole should be protected. (Please mark brainliest)

Rather than helping one species you can help a entire ecosystem. if you think about it, you would be saving more in a ecosystem then you would in just 1 single species

No not all microorganisms cause harm to the human body some bacteria is health and needed in the body to help us break down food
