Answer:

The atmosphere is the largest reservoir of the nitrogen as it is composed of 78% of Nitrogen. Although 78%, this is not used by the organisms directly as the nitrogen molecule exists in nature in the form of divalent joined via triple bonds.

These triple bonds require a great amount of energy to be broken and used. Only a few prokaryotic organisms called nitrogen-fixing bacteria have the capability to break these triple bonds as they contain enzymes-nitrogenase complex which converts the atmospheric nitrogen to usable forms like ammonia, nitrates and nitrites. About 92% of the atmospheric nitrogen is fixed through this way rest through thunderstorms and Haber's process.

Thus, nitrogen-fixing bacteria is the answer.

Answer: Option A.

The hypothalamus is the brain structure responsiblre for regulating thirst, hunger, temperature and sexual behaviour.

Explanation:

Hypothalamus is a part of brain structures located at the floor of the third ventricle below the thalamus and its control the autonomic system.

It controls hunger, thirst, temperature, fatigue, sleep and sexual behaviour . Hypothalamus secretes the anti diuretic hormones which increases the level of water absorbed into the blood by the kidneys and corticotropin releasing hormone which regulate immune system.

We think of termites as insects that eat wood. However, termites cannot digest the wood and rely on a variety of eukaryotic and

omeli [17]

Answer:

Obligate mutualism.

Explanation:

Obligate mutualism: It is defined as each organisms are obligated to each other, they rely on one another, means one species cannot survive without the other species. It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.

Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose. The termites do not have this ability to do this, without the help of protozoa. They are not able to use their energy from the food which is wood, cellulose comes from wood it chews.

So, termites are mutualistic related to protozoans and showing obligate mutualism.
