Answer:
Animals ingest nitrogen in nitrate-containing food after plants use nitrogen containing compounds.
The organic matter decays via decomposers.
N molecules breaking apart via nitrogen fixing bacteria.
N2 is formed via denitrifying bacteria.
Explanation:
Plants utilizes nitrogen compounds with the help of roots. Afterwards these plants serves as source of food for the animals. When both plant or animal dies the decomposing bacteria acts upon to breakdown the complex organic remains of plants and animals into ammonia, which is then subjected to the process of nitrification. Here the ammonia is converted into nitrites and nitrates respectively. Then it is acted upon by denitrifying bacteria and the nitrates and converted into gaseous form of nitrogen.
Answer:
b. Genetically engineered trees could have unexpected interactions with organisms of natural ecosystems.
Explanation:
A genetically engineered tree has had it's dna undergo certain modifications through the use of genetic engineering techniques. Such trees are made to have faster growth rate, resistance to insects and diseases. Environmentalists are concerned about these trees and how they could affect the natural environment causing adverse effects to the natural organisms of the ecosystem.
Answer:
You can compare and contrast based off the information you already have and compare weight hardness and depth
Explanation:
Answer:
Option (B) Ethylene gas is a chemical signal through which ripening fruits trigger the ripening process in other fruits.
Explanation:
The ethylene hormone triggers the ripening process of fruit. However, in order to slow down the ripening process the action of ethylene is to be blocked. All fruits are capable to produce ethylene up to a certain level after which they start ripening. There are some classes of fruits that respond to the external ethylene such as apple, mango, tomato etc.
Hence, option B is correct
