Anonymous users2024-02-07There is no difference, for the producer (generally green plants) the amount of assimilation is the producer's photosynthesis.
The amount of sunlight that is fixed.
1. Biological productivity refers to the ability of organisms to absorb external substances and energy to produce organic substances, which is calculated by the total amount of organic matter produced per unit time, and is generally divided into primary productivity and secondary productivity. The former refers to the total amount of organic matter produced by producers (mainly green plants) per unit of time; The latter refers to the total amount of organic matter produced per unit of time by the assimilation of the food consumed by consumers (mainly animals).
2. Assimilation refers to the total chemical energy obtained from the external environment at a certain trophic level.
It is expressed as the amount of respiration exerted at this trophic level, which flows to the energy of the next trophic level, the energy that flows to the decomposer, and the unutilized energy.
1) For producers (generally green plants), it refers to the amount of sunlight fixed in photosynthesis, i.e., the total primary production (GP).
2) For consumers (generally animals), the assimilation amount represents the energy absorbed by the digestive tract (the food eaten may not be absorbed), and the feces are not included in the assimilation amount, but the energy consumed by breathing is counted.
3) For decomposers (generally saprophytes), it refers to the energy absorbed from outside the cell.

Anonymous users2024-02-06For photosynthetic organisms: assimilation is the total amount of chemical energy obtained from the external environment at a certain trophic level. It is expressed as the respiratory expenditure of this trophic level, the energy of this trophic level flowing to the next trophic level, the energy of this trophic level flowing to the decomposer, and the unutilized amount of this trophic level.
1. For producers (generally green plants), assimilation refers to the amount of sunlight energy fixed in photosynthesis, that is, the total primary production (GP). 2. For consumers (generally animals), the amount of assimilation indicates the amount of energy absorbed by the digestive tract (the food eaten may not be absorbed). 3. For decomposers (generally saprophytes), it refers to the absorbed energy outside the cell.
Whereas, for chemoautotrophs, the assimilation amount is a fixed amount of energy and has nothing to do with solar energy. Look

Anonymous users2024-02-05For green photosynthetic plants, the assimilation amount of the producer is the solar energy fixed by the producer. In the case of nitrifying bacteria, the two have nothing to do with each other.

Anonymous users2024-02-031. The production of fixed solar energy is only suitable for photosynthetic organisms (generally green plants), and the amount of assimilation refers to photosynthesis.
The total amount of organic matter produced, i.e., the total primary production.
2. For consumers (generally animals), after the food enters the digestive road, it is divided into two parts: the amount of assimilation and the amount of feces. The amount of assimilation indicates the amount of energy contained in the small molecule substances absorbed by the digestive tract; The amount of stool is the energy that cannot be assimilated, and belongs to the energy of the previous trophic level.

Anonymous users2024-02-02a. The snail belongs to the consumer, and it cannot be used to convert solar energy into chemical energy, and a is wrong;
b. Chlorella is a lower plant, capable of photosynthesis, able to convert light energy into chemical energy, belongs to the producer, b is correct;
c. Escherichia coli belongs to the decomposer and cannot convert solar energy into chemical energy, c is wrong;
d. Grass carp is a higher animal, belongs to consumers, and cannot convert solar energy into chemical energy
If two wait operations, i.e. wait(full) and wait(mutex), swap places, or signal(mutex) and signal(full) swap positions, when the buffer is full of k products. The producer has produced another product that will wait on the empty when it wants to deposit it in the buffer, but it already has the right to use the buffer. At this time, when the consumer wants to take the product, he will stay on the mutex and not get the right to use the buffer, resulting in the producer waiting for the consumer to take the product, while the consumer is waiting for the producer to release the right to use the buffer, and this mutual waiting will never end. >>>More
Answer: Analysis: The point of view in the question does not recognize the unity of commodity use value and value, which is one-sided. >>>More
Animals are mostly consumers, of course, consumers are also called secondary producers, but animals are some decomposers, and there are three stages of decomposition: physical or biological action, which breaks down animal and plant remains into granular debris; saprophytes act to decompose detritus into humic acid or other soluble organic acids; Humic acid mineralization. In these three stages, the organisms involved in the Cong Broadly are all decomposers. >>>More
Plants can make their own food through photosynthesis, so plants are called producers.
Legal analysis: calculated according to the energy consumption of output value: comprehensive energy consumption of 10,000 yuan of total industrial output value = (comprehensive energy consumption of 10,000 yuan of total industrial output value in the previous year - comprehensive energy consumption of 10,000 yuan of total industrial output value in this year) total industrial output value of the current year. >>>More
