Analysis: This question examines the significance of photosynthesis of green plants and the role of bacteria, fungi and other microorganisms in nature. function, read the pictures and answer.
(1) The photosynthesis of green plants can convert inorganic matter into organic matter, which is not only used to constitute the plant body itself, but also to create food and other means of living for other organisms and humans. It is an important component in nature. The ultimate source of organic matter. At the same time, oxygen is released, which not only meets the needs of plants themselves, but also supplies animals for respiration and maintains the relative balance of oxygen and carbon dioxide in the atmosphere
(2), [1] Saprophytic bacteria and fungi in the picture Microorganisms such as these are decomposers in the ecosystem. Under suitable conditions such as temperature and moisture, they can decompose the remains and relics of animals and plants into [2] carbon dioxide, water, inorganic salts and other inorganic substances, return them to the soil, and be used by green plants. Absorb and utilize to create organic matter. It can be seen that microorganisms such as bacteria and fungi promote the material cycle in the ecosystem.
(3) Most bacteria are beneficial to humans. Please list the beneficial bacteria with the same nutritional methods as [1] in the picture. For example, acetobacteria can be used to make vinegar, lactobacilli can be used to make yogurt, and methane bacteria can be used to make yogurt. Used to produce biogas. (Only one type can be listed. If there are multiple types but there are errors, no points will be awarded)
So the answer is:
Comments: As long as you master photosynthesis The meaning of the function and the role of microorganisms in nature can be answered correctly by combining the meaning of the question and analyzing the graphics.
