Energy Flow and Nutrient Cycling in the Epipelagic Zone of the Ocean

Introduction: “Energy Flow’’ is an environmental process that describes the flow of energy through a food chain and attempts to ascertain the relative importance of various individual component species and feeding relationships within a particular ecosystem.
“Energy” itself is defined as the ability to do work: All living plants and animals expend energy in their environment. All three laws of thermodynamics apply, especially the first: “Energy can neither be created or destroyed, but merely converted from one form to another”. In any ecosystem, energy is lost to the surroundings.
A “Nutrient” is a food or any nourishing substance assimilated by an organism and required for growth, repair, and metabolism. Plants derive nutrients from the physical environment e.g. air, water, and sediment, whereas animals from ingested food. [3]
The term “Nutrient Cycle” describes the exchange and movement of inorganic and organic matter back into the production of living matter.
I will examine the Energy Flow and Nutrient Cycle in one ecosystem: The

The producers, using the process of photosynthesis, will have converted the Carbon-Dioxide into new organic compounds such as glucose. Plants and animals use glucose in the process of respiration to produce energy, while excreting Carbon-Dioxide, and Water. This Carbon-Dioxide that is excreted by the plants and animals can be used again by photosynthetic plants. Fish/Animals eat these plants and assimilate the Carbon into their bio-chemical structure. In this way, Carbon is passed along the food-chain. Eventually, the animals at the top of the food-chain die, and as they fall towards the sea-bed, they’re scavenged upon, and decomposed by bacteria. Overtime, this Carbon may appear as a fossil fuel, and thus may be returned to the atmosphere as CO2, which eventually dissolves into the water -and the cycle begins

    Systems, or networks of interdependent components, function in cycles, so each component or element of the cycle can influence another. Feedback loops are the increase (positive loops) or decrease (negative loops) in a process or component and the fluctuation of any element of the cycle with affect the whole. Different loops interact within ecosystems and create what is referred to as “dynamic equilibrium.” In an elk population, if there is an abundance of elk being born and continuing to reproduce, it will create a healthy and large population, which is a positive feedback loop. The elk provides nutrition for people and other animals, including wolves or coyotes; so excess elk can be helpful to provide caloric energy for other animals (positive feedback loop).…

    Our body functions and consumes gas (O2) differently at rest and in motion. Energy requirement to maintain the body’s condition at rest is very different than the energy requirement during maximal exercise. At rest, the muscle intake of gas is very little, but during activity, oxygen consumption is multiples due to the intense oxygen demands of the muscles. Other parameters that are expected to change during exercise are metabolic rate, heart rate and blood pressure, stroke volume, cardiac output, and total peripheral resistance.…

    After performing this procedure, we obtain a clear definition and view of respiration, in addition to the production of carbon dioxide in organisms from two different kingdoms. A big difference existed betweem the production of carbon dioxide among each creature and that was clearly noticeable in our data. Animals rely heavily on oxygen gas which is the product outcome of Photosynthesis. In the other hand, plants need carbon dioxide and on this experiment the production of carbon dioxide lacked, mainly because Elodea was not allowed to photosynthesize due to the foil covering of the beaker. The Crayfish continued to respire because nothing really interrupted its respiration cycle.…

    The abundance in mangroves at Nudgee Beach provides increased numbers of organisms with habitats and microhabitats that they can accommodate; therefore increasing the overall number of organisms within the entire ecosystem. Each of these organisms must interact with other organisms in order to survive and to find food. The complex feeding relationships between these organisms are divided up into levels that make up the food web [6]. The first level of the food web is made up of autotrophic producers that are…

    LO 2.1 I understand that free energy, the portion of a biological system’s that can perform work when temperature and pressure are uniform throughout the system, is used in systems to cause change. I also understand that empirical data proves all organisms require a constant energy output to maintain organization, to grow, and to reproduce. (Campbell 119-123) LO 2.2 I understand that although free energy is always required in living systems in order to maintain organization, to grow, and to reproduce, there are multiples ways in which living systems use the energy. (Campbell 119-123) LO 2.3…

    The role of carbon dioxide in photosynthesis is that it is used by plants to create glucose and water which is what is used as food for the plant and in turn creates oxygen. After the oxygen is formed carbon dioxide is created from this oxygen and the result is water after attaching itself to hydrogen molecules to create released oxygen which allows humans and other living creatures that need oxygen, to live. This is also…

    When one is not sure of where their energy is coming from or how it is getting to them, it opens many dangers to one’s livelihood. Aldo Leopold discusses these issues in his essay, Good Oak, as well as suggesting solutions to prevent them and improve the environment of the earth in the process. Without energy, a person cannot sustain his or herself for very long, so they must acquire it from somewhere. In addition to acquiring enough energy to keep themselves going, people in today’s society also have an obligation to control their use of energy, preferably making sure not to use more than is necessary to sustain them. A person who does not fully control the sources of their energy should be aware of two things, where their energy is coming…

    Totally different from the water’s cycle, the Carbon cycle was more about chemical elements in the ecosystem-atmosphere. Before diving into the subject, to refresh my memory I went back to read book and article to have a good understanding of this cycle. As asserted by Holli Riebeek, carbon is the backbone of life on Earth and mostly all terrestrial beings are made of carbon. Also, carbon was also the fourth largest element in the universe, forged in the heart of dying stars. An article explaining the origin Carbon by confirming that derivative CO2 (Carbon Dioxide), technically comes from volcanic eruptions, automobile exhaust, and during the process of respiration of plants (Photosynthesis).…

    There's various types of ways an organism can live, one being autotrophic. Autotrophs sustain themselves without eating anything derived from living beings. They're the producers of the biosphere because they can release organic molecules. Most autotrophs get their energy from photosynthesis. They store their chemical energy in carbohydrate food molecules that they build themselves.…

    In each ecosystem there are habitats that vary in size depending on the species of population in size. A healthy ecosystem consists of balance between biotic factors and abiotic factors, also known as “non-living” factors which may include and it’s not limited to sunlight, temperature, precipitation, soil, and etc. These abiotic factors help aid the flow of energy among the abiotic factors. The biotic factors which includes “Living Factors”, may include soil, animals, plants, bacteria, and also fungi. These factors help the food web in each ecosystem in their organizations.…
