Sharks eat fish such as lantern fish and amphipods. These fish are the one who eat types of zooplankton and phytoplankton because zooplankton and phytoplankton produce 80% of our oxygen it is important to keep them alive. If we did not have sharks the other fish populations which will be overcrowded because sharks have been overfished‚ they will eat all the plankton‚ and we would lose

food in stomach content of the fishes‚ it will be described the food habit of the fishes. Some fishes feed directly on plants (eg: phytoplankton or pondweeds or both) and some fishes fed on other animals‚ where the word of ‘’predator’’ usually implies on them (Shelby D. Gerking‚ 1994). However‚ Shelby D. Gerking (1994) also state that some fishes prefer phytoplankton and zooplankton (eg: plankton predator) and benthic predator more prefer pondweed and invertebrates living on the bottom as their nourishment

If Commercial Whaling Was Reinstated What Effects Would It Have On The Environment? The history of commercial whaling is a long dark period in our time. It is full of the bloodshed of many innocent creatures. When commercial whaling started in 1910 the average numbers of whales killed per year were around 12‚000. Then 30 years later the number jumped to 40‚000. This was decimating to the whale populations‚ some near the brink of extinction. Then in 1946 the IWC (International Whaling Commission)

Overview Plankton is a microscopic drifting organism present in most of the water bodies around the world. There are three categories of plankton‚ but only Phytoplankton and Zooplankton are of our interest. Phytoplankton is the primary producer and forms the base of food chain in most water bodies. Among these phytoplankton groups‚ there are some species that harm aquatic organisms mechanically or by toxin production either at low concentrations or by forming high concentration blooms known as Harmful

Invasive Species The invasion of non-native species is one of the United Nation’s top five environmental concerns; however the term invasive species is one which many people do not fully understand. It is a term used in the media‚ by governments and ecologists‚ to indicate to the public that a new species has entered an area‚ and usually very little is said afterwards‚ however many people do not realise the severity and long term effects of invasive species in their area and worldwide.

They are most common in marine and freshwater phytoplankton. Some are heterotrophic. Diatoms‚ on the other‚ are a part of a group called stramenopiles. They are unicellular‚ photosynthetic algae with cell walls that contain silica. Dinoflagellates are a diverse group of flagellate eukaryotic
