Ecosystem energy comes from: solar energy.
1. Ecosystem
Ecosystem refers to the unified whole composed of organisms and environment in a certain space of nature. a unified whole, organisms and the environment interact, constrain each other, continually evolve, and remain in a relatively stable state of dynamic equilibrium for a certain period of time. The scope can be large or small, and they are closely related. The largest ecosystem is the biosphere; the most complex ecosystem is the tropical rainforest ecosystem. Human beings live primarily in artificial ecosystems based on cities and farmlands.
2. Solar energy
The energy of the ecosystem is solar energy. Solar energy shines on the earth's surface in the form of light. absorbed by plants, and is convertedinto energy through photosynthesis, thus forming a food chain, the energy of the ecosystem therefore comes from solar energy. Ecosystem, also known as ecosystem, is a complete system of overall functions through the continuous circulation of materials and flow of energy through the interaction between organisms and between organisms and their living environment .
Solar energy generally refers to the radiant energy of sunlight, which is generally used to generate electricity in modern times. Since the formation of the Earth, living things have survived primarily on the heat and light provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of preserving food, such as manufacturing. salt and dry the salted fish. However, with the reduction of fossil fuels, weWe hope to further develop solar energy. There are two ways to use solar energy: passive use (photothermal conversion) and photoelectric conversion.
Solar power generation is an emerging renewable energy source. Solar energy in the broad sense is the source of many energies on earth, such as wind energy, chemical energy, potential energy of water, etc. Billions of years from now, solar energy will be an ideal, inexhaustible and inaccessible source of energy.
Solar energy is generated by the fusion of internal hydrogen atoms to release enormous nuclear energy, which is the energy of solar radiation. Solar Energy System Most of the energy humans need comes from the sun, directly or indirectly. Plants release oxygen, absorb carbon dioxide and convert solar energy into chemical energy and store it in the bodyof the plant through photosynthesis.
What does ATP mean in biology. What is the role?
This is determined by the efficiency of energy transfer (can be understood as utilization) between adjacent trophic levels, because between two adjacent trophic levels energy is transferred from a trophic level to transfer. the efficiency up to the next trophic level is only 10% ----- 20%. Let's take a simple example to understand.
There is a food chain: rice → leaf roller → farm spider → frog → human. Energy transfer efficiency is calculated at 10%. The proportional relationship that exists in this food chain is: (the proportion is not rigorous and is only used for qualitative reference)
If the rice yield per mu is 10,000 kilograms, it is only enough to feed 1,000 people. kilograms of leaf borers;
p>
1,000 kilograms of leaf rollers sufficedbarely smells to feed 100 kilograms of farm spiders;
100 kilograms of farm spiders are only enough to feed 10 kilograms of frogs;
10 kilograms of frogs are barely enough to feed a body weighing only 1 kg.
Please note that the rice yield here is the annual yield. The kilograms here represent both the weight of nutrients and the weight of energy storage substances, which can be thought of as the amount of energy available. Most energy is lost when moving from one level to another because it cannot be used. Therefore, the higher the trophic level, the more difficult it is for organisms to obtain enough food to survive.
If humans only eat frogs, and frogs only eat spiders... then humans can't survive if they only eat 10 kilograms of frogsthem every year. Therefore, only by lowering the nutritional level and consuming rice as a staple food can people get enough food.
Simply put, the higher the trophic level, the more difficult it is to obtain enough food. This is why the higher the trophic level, the lower the quantity.
(The human trophic level can only be considered the second trophic level considering the main food source).
In biology, ATP stands for adenine nucleoside triphosphate. Adenine nucleoside triphosphate (called adenosine triphosphate) is a high-energy unstable compound consisting of 1 adenine molecule and 1 adenine molecule. composed of one molecule of ribose and three molecules of phosphate groups, also known as adenosine triphosphate, or ATP for short.
ATP is a high energy phosphate compound. In the cells, itcan mutually convert with ADP to store and release energy, thereby ensuring energy supply for various vital activities of cells. Purine is the main raw material for ATP, the energy needed by human cells. The Chinese name for ATP is adenine nucleoside triphosphate, which is the energy needed by human cells.
ATP is generated by IMP and aspartate under the action of adenylosuccinate synthase, consuming 1 GTP and adenylosuccinate, which can be cleaved to adenylate plus fumarate can then be catalyzed by the kinase AMP → ADP → ATP.
Detailed information
Adenine nucleoside triphosphate (ATP) is an energy system that provides energy. It can be simply divided into anaerobic and oxygen-containing energy system. energy system. Oxygen energy system, the first does not require the intervention of oxygen during the generation ofATP, while the second does the opposite. The basic concept of oxygen consumption refers to the amount of oxygen that tissue cells can consume or use. In other words, the amount of oxygen absorbed represents the functioning of the aerobic energy system.
When the aerobic energy system produces ATP, it must consume oxygen. The amount of ATP generated must therefore have some correlation with the oxygen supply. Therefore, measuring oxygen consumption can be used to evaluate energy consumption. Under sufficient oxygen conditions, glycogen or liver fat is completely oxidized and broken down, ultimately generating large amounts of carbon dioxide (CO2) and water (H2O), while releasing energy and energy. generate ATP.
