Junior high school biology questions, several junior high school biology questions

Consumers are not able to produce food directly from solar energy, but can only obtain energy directly or indirectly from the diet of green plants. Bacillus anthracis cannot use light energy to convert into its own organic energy like plants all the time, nor can it use inorganic chemical energy to convert into its own energy like autotrophic bacteria, so it is not a producer. And it can't decompose organic waste into inorganic matter like some bacteria, and it can't act as a "scavenger" of the ecosphere to connect the organic environment and the inorganic environment.

So it's not a decomposer either. Bacillus anthracis uses the energy of the human body, that is to say the energy of indirect use of green plants, parasitic life in the human body, so it is a consumer. There are also bacteria that are not necessarily decomposers, such as nitrifying bacteria are producers, using inorganic chemical energy to convert into organic energy.

1.Producers are autotrophs that can make food from simple inorganic substances;

2.Consumers cannot rely on inorganic substances, but directly or indirectly depend on organic matter produced by producers;

3.The role of the decomposer is the opposite of that of the producer.

4.Bacillus anthracis cannot make organic matter, but must parasitize the human body, so it is a consumer.

I always feel that the decomposers are the decomposers, and the bacteria should be the decomposers.

Answer; 1.Consumer.

2.Not all are decomposers, for example: rhizobia parasitized in living organisms and are consumers.

Nitrifying bacteria are autotrophic aerobic and are producers.

E. coli status in the ecosystem, if it lives in the large intestine, belongs to the consumer, if it is alive.

Living outside the body belongs to the decomposer.

3.Yes. 4.The fertilization process of algae plants is inseparable from water.

5.I don't know. 、

1. Consumers.

2.No, rhizobia.

3 out of 4 can't.

5 don't know,

1. Consumers.

2.No, rhizobia.

3 out of 4 can't.

1. Decomposer.

2. No. 3. No.

4. Inseparable.

5. Because he has many organizational structures, the individuals appear to be large when they are piled up.

1) The purpose of placing it in a dark place for a day and night is: (let the original photosynthesis products in the leaves be consumed, which can be compared and avoid residual starch interference).

2) Through experiments, it can be shown that (CO2) is the raw material for photosynthesis.

3) Put the burning match into the B device, the match (continue to burn), which indicates photosynthesis (the generation of oxygen can maintain the combustion), put the B device in the dark for a day and night, and then put the burning match into this device, the match (extinguished), which is the result of the action of the plant (respiration).
