The Dinoflagellates In The Microbial Loop

500 Words2 Pages

Being an important component in the microbial loop is another significant role of the dinoflagellates in the ocean. Referring to Microbial loop (2011), microbial loop is used illustrate the microbial food web. This general interaction begins with the dissolved organic matter (DOM) as the main energy source. Variety of bacteria consumes DOM as their source of energy which then these bacteria are consumed by protozoans, microbe consumers of bacteria and also algae. Because of the DOM, oceanic bacteria are plentiful of carbon and other components of nutrients. The energy that is gained from the DOM will be utilized all through the different trophic level. While photosynthetic dinoflagellates like zooxanthellae forms mutualistic relationship with other …show more content…

The ocean get its crucial source of DOM from algal and dinoflagellate exudates. Through the exudates, DOM can be introduced into the ocean other than by sloppy feeding and from the waste product excretion from the aquatic organisms. The oceanic bacteria are in competition for the phytoplankton in order to get their share of the organic and inorganic substrates from the process of photosynthesis.
The third major ecological role of the dinoflagellate in the ocean is that they assist the reef-building corals. Dinoflagellates are act as symbionts with many types of protists and invertebrates such as the corals (Coffroth and Santos, 2005). Most of the photosynthetic dinoflagellates carry out symbiotic interactions with other aquatic organisms in the ocean. Dinoflagellates as in zooxanthellae, are found inside the tissues of the corals in the tropical region (Thornton, 2012). Zooxanthellae and the corals interact with each other through

Page #556 Thinking through the concepts 3. Two important types of symbiosis would be Commensalism in which one organism benefits while the other is not affected, and an example of this would be Clownfish and Sea anemone in which the Clownfish lays in the Sea anemone in which is has protection from all other organisms, but the Sea anemone gets nothing in return. Another type of symbiosis would be Mutualism in the case where both organisms benefit from each other allowing them to survive. An example of this would be termites and protozoa, in the way that protozoa in the stomach of the termite allows it to digest. 4.

This laboratory experiment involving invertebrates is conducted to enable students to investigate Daphnia magna’s responses to external stimuli, therefore developing a better understanding and knowledge of homeostasis that occurs in organisms and the reaction and behavior exhibited by the daphnia magna when varying conditions are exposed to the organism compared to its natural environment conditions (Carter-Edwards et al, 2011). In order to understand the experiment, a foundation of information about the chosen organism such as its natural environment and physiology must be understood. According to Clare (2002) and Ebert (2005), Daphnia magna are small planktonic crustaceans belonging to the subclass Phyllopoda, found in lakes and

Relationships Provide an example of: Mutualistic Relationship (both benefit) Coral and Crabs The relationship between Trapezia Crabs and Pociollopora coral on the reefs of Rottnest Island is an example of mutualism as both of species benefit from the interaction with the other organism. The Trapezia Crabs, often called ‘coral crabs’ live amongst the branches of coral and feed on the nutrient-rich mucus it produces, but does not induce any harm on the coral. In return, the crabs provide a form of protection for the coral from many of their predators, and would actively defend the coral from sea stars such as the Crown of Thorns (Acanthaster planci) which is a major treat to the coral. Therefore, the Trapezia crabs and Coral are an example of a mutualistic relationship.

These banks contain coral rubble, seagrass and macroalgae with other invertebrate taxa, which play a key part in the ecosystem. The bank systems contain essential fish habitats, which provide sheltering and foraging grounds. Past studies have indicated these fish assemblages showed a high diversity and biomass of coral reefs. Most of the biomass in the Florida Keys ecosystem is made up of species that stay in channels for most of the day. These signs show that the bank systems are important for the FKNMS for providing a structural support and high productivity for the biodiversity.

The Zombie Worm use their “root-like structures” to latch onto whale bones; the only known source of sustenance (Ennis). The structures extract the dietary needs from the bone after an acid is released and the bone is dissolved (Ennis). The oils and fats are then digested by internal bacteria (Ennis). Though little to none is known about the Yeti Crab their food source is conjectured by scientists. They have come to the hypothesis that the crabs hairs “grow mineral bacteria” (Bliss).

In Graph 1.1 shows that the Asiatic has a higher filtration than the native in the algae concentration. In the first 5 minutes in the algae, the Asiatic clam filtered 0.045 abs/g more than the Native clam. By 10 minutes, the Asiatic clam filtered 0.05 abs/g more than the native, and by 20 minutes the Asiatic clam filtered 0.03221 abs/g more than the Native. These results indicate that the Asiatic has a higher filtration than the Native clam. Similarly, the Asiatic also had a higher filtration rate in the bacteria than the Native clams.

In Caribbean, 36 percent coral reefs are located within 2 km of the inhabited land thus this area of coral reefs ecology have highly susceptible to pressures arising from coastal populations. The extensive construction and development for roads, housing, ports and other development has been required to support both of the residential and tourist populations. The coastal development was poorly managed therefore put stress on coral reefs through direct damage from dredging, land reclamation and sand and limestone mining for construction as well as through less direct pressures such as runoff from construction sites and removal of coastal habitat. Besides that, the loss of mangrove and sea grass which filter sediment and nutrients coming from the land has been widespread in the Caribbean which lead to add the pressure towards coral reef ecology. Next, the increased sediment in the coastal waters reduces the amount of light reaching the coral and hinders the ability of their symbiotic algae which is zooxanthellae for photosynthesis.

This proptosis is reproduced in the ocean by some important nutrients like phosphorous and nitrogen, in some places of the world these nutrients are present in huge quantities because of the workforce of the man, this causes a massive production of this proptosis. Phytoplankton are eaten by small fishes but in these cases is difficult that the depredators can not be able to eat all the phytoplankton, some organisms are eaten and some others just die, both generating trash, the waste effects on the production of oxygen in water causing the problem known as hypoxia. Hypoxia is also known as the dead zone because of the low oxygen it is hard for plants and animals to reproduce or to live and by the time they die. These is more common when is summer, spring or a climate with

Alexandra Edwards Microbial Ecology SoFEX Experiment Phytoplankton are microscopic photosynthetic organisms that inhabit the surface waters of the oceans. Major nutrients such as nitrates and phosphates are required for the growth and exist in abundant supply, yet the production of chlorophyll in particular areas of the oceans by phytoplankton is lower then would be expected (Watson, 2012). Investigations into these high nutrient, low chlorophyll (HNLC) regions, such as the Southern Ocean, have predicted that low iron levels have limited phytoplankton blooms. As proposed in 1988 by John Gribin (Watson, 2012), the addition of iron to the ocean in HNLC areas could increase phytoplankton production. When phytoplankton “bloom”, or rapidly

The Process of Elimination Temptation The darkest, most fickle and most destructive aspect of the human psyche is temptation. As the instigator of evil, it inveigles the mind into fulfilling its deepest desires while paying no heed to the longstanding consequences. It provokes lying, hurting and killing, all of which we observe Macbeth executing in William Shakespeare’s play, Macbeth. By further analysing the actions and motives of Macbeth, I questioned the most devious human aspect.

About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.

They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain conditions to be formed, and to survive. They are also known as the “rainforest of the oceans” because of its huge diversity.
