Answer:
A biological community in which association takes place between the organisms and their physical surroundings is termed as an ecosystem. It can also be defined as an association between the nonliving and living components found within the environment. A particular geographical region, which is specified for the species thriving within it is known as a biome.
A branch of science, which deals with the natural procedures that comprise fire within an ecosystem and the ecological influences it imparts, the association between the biotic and the abiotic constituents of an ecosystem with the fire, and the role played by fire within an ecosystem is termed as a fire ecology.
Different kinds of ecosystems like savanna, prairie, coniferous forests and chaparral have originated by the contribution of the fire, which plays an essential role in the renewal and vitality of the habitat. Different kind of plant species needs the assistance of fire to establish, to reproduce, or to germinate. In case, if the suppression of wildfire takes place, it will eventually result in the eradication of various plant species and the animals that rely upon them.

Answer:
Answered below
Explanation:
On piercing his foot, the pain receptors called nociceptors, found in the skin, are activated. Nociceptors exist at the nerve endings of the primary afferent neurons. Signals travel along the first order neurons which have cell bodies within the dorsal root ganglia of the spinal cord. In the dorsal root ganglia, the signals are taken up at the synapse with the second order neurons which have cell bodies in the nuclei of the cranial nerves within the brainstem. These neurons ascend cranially in the spinothalamic tract to the thalamus. The third order neurons lie within the ventral posterolateral nucleus of the thalamus. They terminate at the somatosensory cortex where the signals are being processed and returned as a sensation of pain.
Answer:The secretion of aldosterone is directly stimulated by adrenoglomerulotropin.
Explanation:
Aldosterone plays an important role in the regulation of systemic blood pressure through the absorption of sodium and water. The lipid factor(adrenoglomerulotropin) which is obtained from pineal extracts selectively stimulates secretion of aldosterone.
