Organisms are under contaminated conditions, and pollutants can be enriched and detoxified in the body through a combination of fixation, metabolic detoxification, and compartmentalization. Among them, the detoxification ability of the organism is the basis of biological resistance, and all organisms with strong detoxification ability are resistant. But detoxification ability is not the whole of resistance. It can be inferred from this:. ['Poorly detoxifying organisms are not resistant.', 'Resistant organisms must have strong detoxification capabilities.', 'Biological can enrich and detoxify pollutants, so biological can survive in a polluted environment.', 'Non-resistance biological detoxification ability must not be strong.']
