Eautrophicaation and biomagnification

What is eutrophication?

* process in which bodies of water become enriched with nutrients causing excess growth of algae


* this algae eventually kills fish and other marine organisms.

draw a diagram of the process of eutrophication

What are some nutrients that cause eutrophication?

phosphorus and nitrogen

What are 3 ways farmers can prevent excess nutrients from entering waterways?

* plant cover crops between growing seasons to prevent soil erosion
* leave soil alone instead of tilling it up so nutrients stay in place
* industries to comply with standards

3 ways unwanted nutrients get into water ways

* poor farming practices
* industrial waste
* human and animal waste

What is biomagnification?

When concentrations of particular non-biodegradable chemicals become more concentrated in the tissue of organisms in successive trophic levels
