Mufasa is talking about the ecosystem. All animals in the ecosystem are connected, and therefore each requires all the others for its survival. If the balance is not respected - for example, if humans wipe out one particular species - the entire ecosystem will suffer as a result. 7) In an attempt to explain the Circle of Life, Mufasa says to Simba; “when we die our bodies become the grass……the antelope eat the grass……” How is this possible? Describe the process that Mufasa is referring to in detail.
An ecosystem can range from a mere backyard garden to a vast land under rainforest. Animal body is sometimes considered as an ecosystem since it can support life. The words "environment" and "ecology" have been increasingly in the news. Man is beginning to fear that his daily activities may be limiting the future use of resources. Pesticide use and drift can affect air quality; pesticides in the food chain can threaten wildlife populations; and soil may no longer be suitable for optimal crop production.
Abstract Intraspecific and interspecific competition plays a major role in stabilizing environments. These mechanisms ensure that no species can go beyond its environments carrying capacity. The purpose of this lab is to determine the effects of density on biomass of plants and the effects of predators and abiotic factors in an environment. This will be tested with the spinach plant Spinacia vulgaris of varying densities in the same sized pots and with the use of P. aurelia, P. bursaria and P. caudatum divided into control and experimental groups. The results showed that the increasing of the density leads to a decrease in the biomass of plants and that the experimental groups are not much different than the control groups.
There is another type of organism that cleans up after the others, and they are called detritivores. Detritivores (or decomposers) use energy from waste or dead organisms, and they complete the cycle by returning nutrients back into the soil or carbon dioxide to the air. The number of trophic levels is limited by the amount of energy available, which is always set. Trophic levels can include tertiary consumers, quaternary consumers, and so on until there is no longer any more energy available for the biggest and neediest consumers. Energy starts from the resource, which would be the sun in almost all cases.
I believe decomposers are the most important trophic level in an ecosystem. In my opinion without the work of these animals, insects, and bacteria our planet would be overrun with rotting carcasses of animals and enormous piles of vegetation. The earth would cease to be able to sustain life because of poisoning of the land and waterways by decaying matter. The decomposers speed the process of decomposition in turn supplying them with food and returning vital nutrients to the earth starting the process all over. What is Biodiversity?
Phosphate comes from a rock that gradually breaks down and will release other ions. Human impacts phosphorus cycle by using phosphorus containing fertilizers to make animal feed, detergents, and other products. This cycle is a common limiting factor in soils and added to croplands to greatly stimulate the production. When this cycle moves from the soil and gradually makes it way to the ocean, it creates problems such as water pollution. The Nitrogen cycle has similarities to the carbon cycle and the phosphorus cycle.
The Action Spectrum and the Absorption Spectrum Introduction: The purpose of this experiment is to learn the rates of photosynthesis under different lights, and the absorbance of photosynthetic pigments in spinach extract. “There would be no biology without photosynthesis. Plant biomass is the food and fuel for all animals. Plants are the primary producers. These amazing organisms are capable of capturing the energy of sunlight and fixing it in the form of potential chemical energy in organic compounds.” (Measuring the rate of photosynthesis) “Light is one of the main factors that affects the rate of photosynthesis, which literally means using light to create something new.” (What Are Three Factors That Affect the Rate Which Photosynthesis Occurs?)
In a plant growing in the dark the chlorophyll will slowly be destroyed causing them to use their food reserves. Once the reserves have been used the plant will die. This is what happens in plants that are not grown in sunlight. Etiolation is a phenomenon that occurs in plants not being grown in sunlight, whereby the stem of the plant rapidly elongates to increase the probability of the plant finding light. In order to carry out this etiolation the plant must use its food reserves, so if the plant does not find light having used these reserves, it will die.
CnH2nOn + nO2 + ADP + Phosphate (+ oxidizing agent and energy from photon [through electrochemical gradient]) → ATP + nCO2 + nH2O Function Carbohydrates play a variety of extensive roles in all forms of life: Carbohydrates are initially synthesized in plants from a complex series of reactions involving photosynthesis. Store energy in the form of starch (photosynthesis in plants) or glycogen (in animals and humans). Provide energy through metabolism pathways and cycles. Supply carbon for synthesis of other compounds. Form structural components in cells and tissues.
According to Hopkins (2006), photosynthesis is the process by which green plants and certain organisms transform itself from light energy into chemical energy. As a straight forward chemical reaction in which carbon dioxide comes from the air, along with the midair and water from the soil, photosynthesis conglomerates to produce what is known as carbohydrate (p. 6). Solar Energy produced by photosynthesis, stores itself in a chemical bond of a carbohydrate molecule. Sugar known as glucose is then formed which becomes convenient both by way of energy to be stored for later use in tissues or by way of carbon to be used for cells (p.7). Hopkins, w. G. (2006).
