Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
The tissue takes in carbon dioxide and releases oxygen. There are three different kinds of tissue types like the dermal, ground, and vascular. The dermal tissue is made of tightly together cells that make a covering which is used to help prevention of water loss called epidermal cells. Ground tissue has commonly found parenchyma, collenchyma, and sclerenchyma cells in itself. Vascular tissue has the job to transport the food, water, hormones, and other minerals inside the
One of the main reasons why water is so important is that water is median for transferring heat on earth. When our body releases energy, it is released as a form of heat, which the water absorbs almost instantly and evaporate it off of our skin, causing the "cool" sensation. With that being said, water is in our cells in a vacuum called the vacuole. In human, it is mainly to keep our entire body hydrated and clean, but in plants, water is broken down in photosynthesis, which converts carbon dioxide and water into oxygen and energy(carbohydrates). Water also controls our climate weathers.
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.
P4- Explain the Physiology of two named body systems in relation to energy metabolism in the body. In this essay I am going to be explaining how energy is made in the body and two body systems that help to produce this energy. “The metabolic systems are responsible for the chemical reactions within the body. These reactions are involved in the maintenance of the living organism and may be involved in reactions that break compounds down catabolic reactions or reactions which build compounds up anabolic reactions”. (King R 2012) They all require energy to work.
The glucose is dissolved and the body releases it’s built up energy, after this the oxygen is transformed into liquid and atoms from the molecules are discharged as carbon dioxide. They are two major parts required to convert glucose into carbon dioxide and water; those steps are glycolysis and aerobic respiration. During cellular respiration the body main objective from the equation is the energy, so the byproducts are the water (H2O) and carbon dioxide (CO2). The carbon dioxide is then expelled into blood and carried to the lungs and then exhaled out of the body. The water attached to the blood cells also, but it is eliminated from the body through sweat and urine from the kidneys.
All living organisms depend on continuous transfers of energy; they require energy to allow certain processes in the body to occur, such as active transport, DNA replication, cell division, protein synthesis, muscle contraction, homeostasis, etc. These are important so that organisms can continue to survive. In this essay, I am going to highlight the way energy is transferred, firstly from the environment to organisms, and the energy transfer between organisms. The main route by which energy enters an ecosystem is photosynthesis. Photosynthesis is the process where light energy is converted into chemical energy in the form of glucose.
For instance Carbon Dioxide from the atmosphere is synthesized by plants, which is ingested and metabolized by animals, which is converted to Carbon Dioxide during respiration and decay. Humans remove over 40% of the photosynthetic that effort plants in order to support human enterprises. When humans burn fossils fuels that increases the atmosphere Carbon Dioxide by 35%, then during the combustion stage the present of air (oxygen), Carbon Dioxide and water molecules are release into the atmosphere. Human has an impact on the Phosphorus Cycle as well as the Carbon Cycle. The Phosphorus Cycle is representative of the cycle of all biologically important mineral nutrients-those elements that have their origin in the rock and soil minerals of the Lithosphere, such as iron, calcium, and potassium.
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).
In plants the way they get there energy is through sun light where they have process called photosynthesis where they produce and release oxygen in the air. Photosynthesis requires direct sunlight, carbon-dioxide, and water. In this process of photosynthesis, plants decompose the molecules of hydrogen and carbon dioxide into hydrogen, then carbon and oxygen produces glucose which forms their source of energy, food and growth. Solar cells similar to this process get sunlight where light in the form of photons hits the solar cell and are absorbed by semiconducting materials such as silicon. Negative electrons are break free from their atoms, causing them with an electric potential difference.
