Johnny just learned about ecosystems in his class at school. At dinner, he explains to his parents that we live in an ecosystem and they are a mix of biotic and abiotic factors. He then tells them an ecosystem can still survive even if one small thing is missing such as nitrogen in the soil. His dad explains that the ecosystem would not be able to survive. Is dad correct or is Johnny correct?
