Answer:
The correct answer will be- the amount of ammonia will decrease in lithosphere and the amount of nitrogen in atmosphere will increase.
Explanation:
Nitrogen is the most abundant element present in the atmosphere as it constitutes 78% of the atmospheric gases.
The major cause of nitrogen fixation on Earth is biological nitrogen fixation which takes place due to the ability of prokaryotes to utilize atmospheric nitrogen as they possess an enzyme called nitrogenase. The nitrogenase converts the atmospheric nitrogen to a usable form that is ammonia (NH₃).
In the given condition, if virus inactivates the nitrogenase enzyme, then atmospheric nitrogen will not be converted to ammonia as a result of which the Amount of ammonia of soil decreases in the soil and the atmospheric nitrogen will increase.
Interspecific competition can occur between two different species competing for the same resource in an ecosystem. So for this particular bug population, there may be another insect species that competes for the same food source or another resource, such as material or space for breeding habitat. This can lead to selective pressure, and may result in the different species evolving a more specific diet or inhabiting a niche environment.
