For photosynthetic organisms: Assimilation quantity is the total chemical energy obtained from the external environment at a certain trophic level. It is expressed as the respiratory consumption of this trophic level, the energy flowing from this trophic level to the next trophic level, the energy flowing from this trophic level to the decomposers and the unused quantity of this trophic level. 1. For producers (usually green plants), assimilation refers to solar energy fixed during photosynthesis, i.e. total primary production (GP). 2. For consumers (usually animals), the amount assimilated represents the energy absorbed by the digestive tract (not all food consumed can be absorbed). 3. For decomposers (usually saprophytes), it is the absorption of energy outside of cells. For chemoautotrophs, the amount of assimilation is energy fixe and has nothing to do with solar energy
How to calculate the total amount of fixed solar energy for producers The following trophic levels are given from the top
The poster must first know that chemosynthetic bacteria are also producers.
Thus, producers' fixed solar energy refers to the energy fixed by photosynthesis by bacteria and plants capable of photosynthesis.
The quantity assimilated by producers: in addition to the above, it also includes the energy fixed by chemosynthetic bacteria.
Why is the solar energy received by plants not the total energy flowing through this ecosystem?
Forget it. The total amount of solar energy fixed by all producers in the ecosystem is the total energy flowing through the ecosystem. When it crosses the first trophic level (producers), the energy passes: part of the producteurs breathes and some of it flows to the next trophic. At level , part of the energy contained in producer remains, dead branches and leaves is broken down and released by decomposers.
Why is the solar energy received by plants not the total energy flowing through this ecosystem?
Because part of the energy is not used in a fixed way and is lost
Is solar energy fixed by plants equal to all the energy circulating through the ecosystemThe energy that flows through the ecosystem is not only solar? energy absorbed by plants., the ecosystem consists of all animals and plants + the inorganic environment, so unabsorbed solar energy can flow through the ecosystem as thermal energy.
Does the total energy flowing through an ecosystem include unused energy?Yes. Since the total energy flowing throughIf the ecosystem is fixed solar energy from plants and other producers, downstream consumers must have unused energy, and it has already been included.
(The classification of this question should be biology)
What is the total energy flowing through the ecosystem that green plants fix through photosynthesisSolar energy
Logistics for high school students What is the total energy of an ecosystem?At the high school level, the total energy circulating in the ecosystem is the solar energy fixed by the producers. Chemosynthesis does not count, nor do organic pollutants. High School Biology What exactly is the total energy flowing through an ecosystem!
The total energy flowing through an ecosystem is the energy stored by the biological components in the diagram. What is the difference between stored total energy and fixed total energy?
Fixed energy can also exist inabiotic components, such as feces, etc.
High School Biology: Why is the total energy flowing through the ecosystem in the artificial wetlandObjects: Why is the total energy flowing through the constructed wetland The total energy of the ecosystem is
Constructed wetlands, with human intervention,
can provide energy, such as food.
Why does the energy of an ecosystem not come from solar energyBiota of deep-sea underwater volcanic craters, their energy comes from the temperature generated by underground magma and minerals ejected from the volcanic crater.
Why is it wrong that the energy of the ecosystem comes mainly from solar energy, except solar energyThere should only be solar energy. Because the energy of the ecosystem comes from the light energy fixed by the producers. Geothermal energy is notnot accessible to producers.
Solar energy received by plantsThe solar energy received by plants is certainly not the energy from the sun that illuminates them, because part of the sunlight is not absorbed by the plants but is reflected (green) and processed. . . In addition, sunlight also carries thermal energy, how can it be completely absorbed?
Biologically, solar energy received by plants refers to the energy that plants assimilate in their bodies through photosynthesis. is the total energy entering the ecosystem.
