Nitrogen Cycle – Definition, Steps, Importance, Examples

Nitrogen Cycle - Definition, Steps, Importance, Examples

What is Nitrogen Cycle? Nitrogen Cycle Definition The nitrogen cycle is a biogeochemical process that transforms atmospheric nitrogen into usable forms for living organisms and then returns it to the atmosphere through a series of biological and chemical reactions. Stages of Nitrogen Cycle Nitrogen fixation, nitrification, assimilation, ammonification, and denitrification are the steps in the … Read more

Denitrification – Definition, Process, Factors

Denitrification - Definition, Process, Factors

What is Denitrification? The nitrogen cycle concludes with denitrification. The nitrogen cycle consists of living organisms fixing atmospheric nitrogen and then releasing it back into the atmosphere. Denitrification is the process of releasing nitrogen from living organisms into the atmosphere. Denitrification Process Denitrification is the last step in the nitrogen cycle. It is a naturally … Read more

Bioaerosol - Definition, Types, Collection, Transmission

What is Bioaerosol? Types of bioaerosols 1. Fungi 2. Bacteria 3. Viruses 4. Pollen Collection Methods of Bioaerosol/Deposition of Bioaerosol Bioaerosols are primarily collected via collection plates, electrostatic collectors, mass spectrometers, and impactors. Other experimental approaches are also utilised. In comparison to other PC filter alternatives, Polycarbonate (PC) filters have produced the most accurate bacterial … Read more

Bioremediation – Definition, Types, Application

Bioremediation - Definition, Types, Application

What is Bioremediation? Bioremediation is a process used to clean up and detoxify polluted sites by utilizing microorganisms, plants, or their enzymes to break down and degrade environmental contaminants. It involves the natural or deliberate introduction of these biological agents to enhance the rate of degradation and transformation of pollutants. The concept of bioremediation includes … Read more

Mycorrhiza – Definition, Types, Examples, Importance

Mycorrhiza - Definition, Types, Examples, Importance

What is Mycorrhiza? Definition of Mycorrhiza Mycorrhiza refers to the symbiotic association between specific fungi and plant roots, where the fungus aids in nutrient and water uptake for the plant, and in return, the plant provides the fungus with essential nutrients produced through photosynthesis. Types of Mycorrhizae Mycorrhizas are often classified as either ectomycorrhizas or … Read more

Microbe-Plant interaction – Types, Examples

Microbe-Plant interaction - Types, Examples

Microbe-Plant interaction Plants are immobile, but they are continuously subjected to both biotic and abiotic stress. Constant warfare exists between harmful microorganisms and the host plant, with the outcome determining resistance or disease. Plants exude a variety of organic substances, resulting in a nutrient-rich environment that is conducive to microbial growth. Therefore, plants are highly … Read more

Nodulation – Steps, Structure, Functions

Nodulation - Steps, Structure, Functions

What is Nodule? Root Nodule Types In legumes, two major forms of nodules have been identified: determinate and indeterminate. Determinate nodules Indeterminate nodules Symbiosis Leguminous family Non-leguminous Root Nodule Formation Steps – Nodulation Briefly Describe When the soil contains a low concentration of nitrogen, root nodule development begins. The two symbiotic partners rely on cell … Read more

Nitrogen Fixation – Definition, Importance, Processes

Nitrogen Fixation - Definition, Importance, Processes

What is Nitrogen Fixation? Nitrogen fixation is the fundamental biological process and the first step in the nitrogen cycle. Certain bacterial species, such as Rhizobium, Azotobacter, etc., and other natural phenomena convert atmospheric nitrogen into ammonia (another type of nitrogen) throughout this process. Why is Nitrogen Fixation Necessary? It serves the following functions in nature: … Read more
