What is the Difference Between Eutrophication and Biological Magnification?
🆚 Go to Comparative Table 🆚Eutrophication and biological magnification are two processes that occur due to environmental pollution and have detrimental effects on both animals and humans. Here are the key differences between the two:
Eutrophication:
- Eutrophication is the process of excessive growth of algae due to the enrichment of water bodies with nutrients like nitrates and phosphates.
- It results in algal blooms, which cause coloration of water and can lead to the depletion of dissolved oxygen in water, potentially killing aquatic organisms such as fish.
- The main chemicals responsible for eutrophication are nitrates and phosphates.
Biological Magnification:
- Biological magnification, also known as bioaccumulation or biomagnification, is the process by which the concentration of harmful non-biodegradable substances increases at each trophic level of the food chain.
- This process leads to the accumulation of toxic compounds, especially in higher trophic levels, with apex predators such as fish-eating predatory birds like kingfishers and loons being particularly vulnerable to poisoning.
- The main substances responsible for biological magnification include DDT, PCB, dioxins, and furans.
In summary, eutrophication is the excessive growth of algae in water bodies due to nutrient enrichment, while biological magnification is the increase in the concentration of harmful non-biodegradable substances at each trophic level of the food chain. Both processes are caused by environmental pollution and have adverse effects on both animals and humans.
Comparative Table: Eutrophication vs Biological Magnification
Eutrophication and biological magnification are two distinct processes that occur in aquatic ecosystems. Here is a table comparing the differences between them:
| Process | Description | Outcome |
|---|---|---|
| Eutrophication | The nutrient enrichment (i.e., addition of nitrates and phosphates) of a water body, resulting in the growth of aquatic plants, especially algae, causing coloration of water known as algal bloom. | Depletion of dissolved oxygen in water, leading to the death of aquatic organisms (e.g., fish). |
| Biological Magnification | The increase in the concentration of harmful non-biodegradable substances (e.g., pesticides and heavy metals) in the body of living organisms at each trophic level of the food chain. | Poisoning of predatory birds that eat fish, such as kingfishers, ospreys, and loons. |
In summary, eutrophication is about nutrient enrichment and its effects on water quality, while biological magnification is about the increasing concentration of harmful substances in the bodies of living organisms at each trophic level of the food chain. Both processes have detrimental effects on both animals and humans.
