beat to produce a constant current of water‚ allowing particles to be filtered by fine setae on the thoracic legs. The particles are then transferred to their mouth groove to be ingested. D. magna typically feed on planktonic algae (Ebert‚ 2005). The following experiment uses algae to test what affects the feeding rate of D. magna. The rate of filtration is dependent on multiple factors including temperature‚ food density‚ body size‚ and water pH.

concentration of nutrients‚ the giant kelp can grow up to two feet per day and over 100 feet in it’s lifetime. Although they can only live for about six years‚ the giant kelp is the largest alga in the ocean. Kelp forests consist of two types of algae: giant and bull. Giant kelp can live for several years‚ while bull kelp can only survive for one. Both types of kelp have a two-stage life cycle. In the earliest part of their lives‚ they exist as spores‚ along with millions of their brothers and

Eutrophication and health 40 preface Eutrophication and health Algal blooms‚ “red tides”‚ “green tides”‚ fish kills‚ inedible shellfish‚ blue algae and public health threats. What is the common link ? The answer is‚ EUTROPHICATION: a complex process which occurs both in fresh and marine waters‚ where excessive development of certain types of algae disturbs the aquatic ecosystems and becomes a threat for animal and human health. The primary cause of eutrophication is an excessive concentration

The impact can be devastating because there are assortments of the fish that are caught that may have been contaminated with toxic algae and many fish are killed as a result. 3.
