Zoology experiment: The Predator-prey Interactions Between Zebrafish and Daphnia 1. Six 1-L beakers were filled with aged tap water. 2. To test the effect of light on the survival of Daphnia, the 6 beakers were divided equally into 2 treatments: light & dark. Beakers assigned to the dark treatment were covered w/ aluminum foil. 3. One zebrafish (about 2-3 cm) starved for 24 hours was placed in each beaker. 4. Fifty (50) Daphnia sp. individuals were added in each beaker containing the starved zebrafish. The top of the beakers assigned to the dark treatment were covered with aluminum foil. 5. One hour after, the zebra fish was scooped out & the no. of surviving Daphnia in each set-up were counted.  How did light exposure affect the survival of Daphnia when exposed to a predator?

Classification of Marine Organisms

Classification is a way of categorizing organisms that enables an easy process of identification of such organisms. All living things are classified by grouping them under specific categories. The grouping is done based on the close relativeness of the organisms. The classification tool requires knowledge of characteristics, differences, and similarities between different organisms.
