Answer:
Photosynthesis
Photosynthesis. Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
<u>Conservation is the most important strategy in the soil management programs of agriculture</u>
In the soil management various practices are followed which will help to conserve the soil and so as to increase the fertility of the soil. Being the most important step conservation is very mandatory, as the building up of new soil will take a lot of time. It also protects the soil from the bad weather and protects the erosion. In conservation process it helps in the nutrient preservation, which can give good yield when practised cultivation. More crops can be easily grown , which will fetch more money. The conserving soil can also help in biochar fertilizer.
1 you run out of fuel 2 it takes a long time 3 it’s hard to get back 4 the conditions are constantly changing making it harder to predict what could happen. Look at Apollo 12 as a example
Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
