What do the plants convert the nitrates and nitrites into after they fix the atmospheric nitrogen? Correct Answer Amino acid

Concept-

The nitrogen cycle is a biogeochemical process that converts inert nitrogen in the atmosphere into a form that can be used by living organisms.

Key Points

  • The nitrogen cycle begins with this phase.
  • Atmospheric nitrogen (N2), which is predominantly available in an inert form, is transformed to the useful form -ammonia- in this process (NH3).
  • The inert form of nitrogen gas is deposited into soils from the atmosphere and surface waters during the nitrogen fixation process, primarily by precipitation.
  • Later, the nitrogen undergoes a series of modifications that result in the separation of two nitrogen atoms, which mix with hydrogen to produce ammonia (NH4+).
  • The entire nitrogen fixation process is finished by symbiotic bacteria known as Diazotrophs.
  • Azotobacter and Rhizobium are other important players in this process.
  • The nitrogenase enzyme in these bacteria is capable of combining gaseous nitrogen with hydrogen to produce ammonia.
  • Nitrogen fixation can take place in two ways: through atmospheric fixation, which includes lightening, or through industrial fixation, which requires the production of ammonia at high temperatures and pressures.
  • Man-made operations, especially industrial ones that produce ammonia and nitrogen-rich fertilisers, can also help.

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resources of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soils. They help in the maintenance of biological diversity of predators and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative. Which of the following statements is/are correct regarding biopesticides? 1. They are not hazardous to human health. 2. They are persistent in environment. 3. They are essential to maintain the biodiversity of any ecosystem. Select the correct answer using the code given below.
