The effect of caffeine on the heart rate of Daphnia pulex
Introduction
In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well. Carrie miller from university of Michigan states on the website Animal diversity web states that Daphnia are important in the food chain of common fish that we eat such as sticklebacks, minnows, young Sockeye salmon and trout. However the daphnia also competes with these organisms for food and …show more content…
Daphnia is also used to clean fish tanks because they eat the algae. Daphnia is also used in scientific experimentation because of their see through body and they are easy to maintain in a laboratory. The Daphnia live near the algae rich area of a river. Daphnia is not an endangered species and are found throughout the world. The joint Genome institute states that Daphnia typically feeds on Algae and Bacteria, they are also an indicator species to environmental change. They occupy a crucial position in food webs. Daphnia also live in both deep lakes and shallow ponds. In the scientific journal Ecology, Etymology and evolution and parasitism in Daphnia by Dieter Ebert 2005 it is stated that Daphnia are asexual. Planktivorous fish feed on Daphnia also Glassworms are known to feed on Daphnia. This experiment is interesting because the effect of caffeine on living organisms has been proven
