Is dodder a producer or a consumer

Dodder. It is a parasitic plant that lives by absorbing nutrients from its host and is a consumer.

in the ecosystem.

All kinds of living things, living things and non-living things are closely related, and they are interdependent and mutually restrictive.

Producers mainly refer to green plants that are able to photosynthesize.

the production of organic matter to provide matter and energy for itself and other organisms in the biosphere; Consumers are mainly animals of all kinds, which must feed directly or indirectly on plants and play an important role in promoting the circulation of matter in the biosphere;

Decomposers are saprophytic microorganisms such as bacteria and fungi that can decompose organic matter from animal and plant residues into inorganic matter.

The return of the inorganic environment promotes the circulation of matter.

The various components of ecosystems are interconnected, interdependent and indispensable. Changes in one component often lead to corresponding changes in other components, and even a series of changes occur in the entire ecosystem.

role

The role of the decomposer: The decomposer breaks down the dead organism into simple inorganic matter and releases energy, in which the inorganic matter can be reused by the plant to maintain the cycle of the ecosystem.

Producer role:

1. Photosynthesis.

That is, the synthesis of light energy, is plants, algae.

and certain bacteria, under the irradiation of visible light, undergo light reaction and carbon reaction, using photosynthetic pigments, carbon dioxide.

or hydrogen sulfide. and the biochemical process in which water is converted into organic matter and oxygen (or hydrogen) is released. 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.

2. Chemical energy synthesis.

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.

Cuscuta is a consumer.

Cuscuta is a plant with a special physiological structure, its cells do not have chloroplasts, and it uses climbing stems to climb to other plants, and develops into specialized suckers from the part that contacts the host, enters the host and reaches the phloem, absorbing nutrients for survival. Cuscuta lives on parasitism and belongs to consumers.

Habits

Cuscuta is a holoparasitic plant that specifically parasitizes on the stem of the host, but its selection of hosts is usually not specific, i.e., it is possible that the same species of dodder will have different hosts.

Unlike most species that parasitize the roots of the host, the endosperm has sufficient resources (nutrients) to provide germination. Although the seeds of Cuscuta can remain dormant for up to 5 years after falling to the surface, the nutrients in the endosperm of the seeds only provide 6 days after germination for it to establish a connection with the host (generate a sucker into the host).

Question 1: Is Cuscuta a producer, consumer or decomposer Cuscuta is a parasitic plant that lives by absorbing nutrients from its host and is a consumer.

Question 2: What do high school biology producers, decomposers, and consumers refer to? Be specific, and give exceptions.

The teacher said that plants are not all producers, and that autotrophic organisms play an important role in the carbon, nitrogen and sulfur cycles in nature. Often producers. Heterotrophic organisms can act as decomposers, consumers in ecosystems.

Question 3: Cuscuta is a flowering plant lacking chlorophyll, which can be adsorbed on other green plants in Myeongdong to obtain nutrients, so the role of Cuscuta in the ecosystem is ( a, the biological components of the ecosystem are producers, consumers and decomposers Producers refer to organisms that live autotrophically, mainly referring to green plants, and the role of these foods is to provide nutrients and energy for themselves and other organisms in the ecosystem, a false; b. Decomposers are mainly saprophytic organisms, which can decompose the organic matter contained in animal and plant residues into simple inorganic matter, return it to the inorganic environment, and promote the material cycle of the ecosystem. c. The leaves of Cuscuta are degenerate, the stems are yellow or yellow-brown, grow on soybeans, citrus and other plant bodies, cannot photosynthesize to make organic matter, and survive by absorbing water and nutrients in the plant, which belongs to consumers, and C is correct; d, that is, the decomposer is also the consumer, d is wrong, so choose: c

Cuscuta is a parasitic life and is a consumer.

Cuscuta chinensis lam), also known as Zen Zhen, Bean Parasitism, Bean Yama King, Yellow Silk, Yellow Silk Vine, Chicken Blood Vine, Golden Silk Vine, etc.

Annual parasitic herb. The stems are winding, yellow, slender, leafless. The inflorescences are lateral, with few or many clusters of flowers forming small umbels or small clusters of umbels; bracts and bracts small, scaly; peduncle slightly stout; calyx cup-shaped, commissurated below the middle, lobes triangular; corolla white, pot-shaped; stamens bearing corolla lobes bent slightly below; scales oblong; The ovary is nearly spherical, columella 2.

The capsule is spherical in shape, almost entirely surrounded by a corolla. Seeds 2-49, light brown, ovate, about 1 mm long, with a rough surface. It is found in China, Iran, Afghanistan, Japan, North Korea, Sri Lanka, Madagascar, and Australia.

It grows at an altitude of 200-3000 meters above sea level on the edge of fields, on mountain slopes, roadside shrubs or seaside sand dunes, and is usually parasitic on a variety of plants such as legumes, Asteraceae, and Tribulaceae.
