Homeostasis

Explanation:

Homeostasis: It is referred to as the ability of a species to maintain a state of internal balance and changes in outside factors. When calcium levels decrease in the human body, the gland known as parathyroid releases hormones. If calcium levels increase, the thyroid gland helps out the calcium by lowering blood calcium levels and fixing calcium in the bones.

Glucose is known as the basic form of sugar. When glucose levels increase in the human body, the gland which is called Pancreas helps to releases a hormone known as insulin. If blood glucose levels decrease, the liver helps to converts glycogen which is present in the blood to glucose.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
