(1) corn and peanut in the spatial structure of the community has obvious stratification phenomenon, can fully utilize the light energy, light intensity is less than 2, corn and peanut intercropping of photosynthetic intensity is greater than monocropping, improve the photosynthetic efficiency, so in the appropriate light intensity, the unit time per unit of leaf area accumulates more organic matter is intercropping planting.

(2) intercropped peanut due to the influence of corn, receiving light energy is not as sufficient as in monocropping, the light reaction provides less ATP and [H], resulting in a reduction in the reduction of three-carbon compounds of the dark reaction, the rate of photosynthesis decreased.

(3) Corn is a C4 plant, the ability to use carbon dioxide is stronger, the dark reaction fixes more carbon dioxide, photosynthesis is stronger.

(4) Fats can be colored orange by Sudan III dye.

(5) Ferrin's reagent water bath heating is used to detect the presence of reducing sugars, yeast in the anaerobic conditions can be anaerobic respiration to produce alcohol, you can use acidic potassium dichromate solution, you can detect the presence of alcohol.

The answers are (1) Intercropping? Layering

(2) ATP and [H]three-carbon compounds

(3) Dark reaction

(4) Sudan III stain

(5) Containing soluble reducing sugars Whether alcohol is produced under anaerobic conditions
