Nan experiment two potted plants, labeled plant 1 and plant 2, are placed in transparent plastic bags and left in the open. sodium hydrogen carbonate is added to the bag covering plant 1. this compound decomposes slowly to produce carbon dioxide. soda lime is added to the bag covering plant 2. this compound absorbs carbon dioxide. both plants are watered regularly with the same amount of water. after several days, starch test results indicate starch in leaf 1 but an absence of starch in leaf 2.this experimental data confirms the

Carbon dioxide is required for process of photosynthesis.

Explanation:

Photosynthesis is the process that fixes carbon dioxide into glucose in the presence of sunlight. The excess of glucose is stored in form of starch in plants. Unavailability of carbon dioxide to plant 2 (due to the presence of soda lime in the bag that absorbed it) did not allow the photosynthesis to occur leading to the absence of starch in this plant. The experiment confirms that carbon dioxide is required for the process of photosynthesis to occur.

100 dollars because yeah

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
