Why are plants called producers, which plants are not producers, and what plants are not

Plants can make their own food through photosynthesis, so plants are called producers.

Green plants can use solar energy to fix carbon dioxide, which becomes the substance needed for their own growth and development. (Converting solar energy [inorganic energy] into chemical energy).

While other species cannot, they need to get their energy from plants.

For example, if a lion eats a goat, although the lion's energy is obtained from the goat, the goat eats grass, and ultimately the lion's energy is actually obtained from plants.

Do you understand that?

Because plants can absorb sunlight and so on to grow, and some small animals feed on these plants, thus providing food for carnivores, thus forming a food chain

Organisms that have photosynthesis and can produce carbons and hydrates independently can be called producers.

Because plants can convert inorganic matter into organic matter for consumer use, it is called a producer.

Able to carry out photosynthesis (the synthesis of inorganic matter into organic matter while converting light energy into chemical energy), it is the substance and energy of other living beings.

Because it is the first of the energy in the biological chain, only plants can photosynthesize and produce biomass energy.

Inorganic substances are subjected to a series of plant cycles to produce organic matter and release oxygen.

It converts inorganic matter into organic matter so that energy can be transferred between the food chain.

The producer does not have to be a plant. In addition to the important producers of green plants that carry out photosynthesis in nature, there are some low-level algae that can also carry out photosynthesis, which are also very important producers in nature, and there are also some autotrophs that produce organic matter (such as nitrifying bacteria) through chemosynthesis, which are also a class of producers.

Producers mainly refer to green plants, including all higher plants, algae and lichens that can carry out photosynthesis. In addition to green plants, there are photoautotrophic microorganisms and chemoautotrophic microorganisms that use solar energy or chemical energy to convert inorganic matter into organic matter. Producers can not only produce organic matter in the ecosystem, but also convert solar energy into chemical energy while synthesizing inorganic matter into organic matter, which can be stored in the generated organic matter.

Photosynthesis

Photosynthesis is the synthesis of photoenergy, which is a biochemical process in which plants, algae and certain bacteria, under the irradiation of visible light, undergo light reaction and carbon reaction, use photosynthetic pigments to convert carbon dioxide (or hydrogen sulfide) and water into organic matter, and release oxygen (or hydrogen). Photosynthesis is the sum of a series of complex metabolic reactions, which is the basis for the survival of the biological world and an important medium of the earth's carbon and oxygen cycle.

Chemosynthesis action

There are certain microorganisms in nature, which can use carbon dioxide as the main carbon source and inorganic nitrogen-containing compounds as the nitrogen source to synthesize cellular matter and obtain the energy needed for growth by oxidizing external inorganic substances. The mode of nutrition carried out by these microorganisms is called chemosynthesis. For example, nitrifying bacteria include nitrosifying bacteria and nitrifying bacteria.

Organic matter is synthesized using the energy released by the oxidation of NH3 and HNO2.

1.Plants such as dodder seed, large flowering grass, gastrodia, pitcher plant, Japanese water hosta, Japanese orchid, solitary orchid, etc., are not producers.

2.Parasitic plants such as dodder seeds, macroflora, gastrodia and certain insectivorous plants such as pitcher plants belong to special status consumers.

3.Some saprophytes belong to decomposers, such as Japanese water hosta and Japanese orchid, which live in saprophytic soil on forest humus, and their roots have mycorrhizal formation.

4.Many orchids are semisaprophytic, such as the solitary orchid.

The details are as follows.

1.Plant-based products are essential food for humans and other animals2Products produced by plants have biological characteristics such as genetics, variation, growth, development, etc.3

There is obvious seasonality, periodicity, such as the sowing of false seeds, the loss of production may be a year's loss. Because agricultural production is obviously seasonal, after the sowing period, it is impossible to replant. 4.

It has the characteristics of continuity and irreversibility, such as the growth period of wheat regreening, jointing, heading, flowering, grain filling, and maturity are continuous processes, and the order of the finch is impossible to reverse. 5.Influenced by natural conditions6

Technological progress is slower7Severely constrained by the amount of land 8It is difficult to control.

Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, and familiar organisms such as green algae and lichens. Plants can be divided into seed plants, bryophytes, ferns, etc., and it is estimated that there are about 450,000 species in existence. Most of the energy of green plants is obtained from sunlight through photosynthesis, and temperature, humidity, light, and fresh water are the basic needs of plants for survival.

Angiosperms have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalysis of enzymes, water, inorganic salts and carbon dioxide are used to carry out photosynthesis per acre, release oxygen, produce glucose and other organic matter, for plant use.

Plants produce oxygen through photosynthesis and provide humans with food such as vegetables, fruits, and more.

The principle of plant production: to regulate the growth environment and life activities of plants through artificial measures, so that they can grow and develop in the direction that people want, and then provide the products needed by human beings.

Characteristics of plant production: extensive dependence on social economy, subject to certain biological laws, controlled by climatic conditions, inconsistency of production time and labor time, regional and seasonal production, orderly and comprehensive production.

The mission of plant production: to study the law of growth and development of cultivated plants, the formation law of yield and quality and the relationship between them and environmental conditions, and to establish the basic theory and technology to achieve high prudent and rapid production, high quality and efficient cultivation.
