Abiotic elements are air, rocks, and water and biotic elements are insects, animals, and trees.
Biotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil, and atmosphere. The way these components interact is critical in an ecosystem.
A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors. In turn, biotic factors can limit the kinds and amounts of biotic factors in an ecosystem.
Therefore, Abiotic elements are air, rocks, and water and biotic elements are insects, animals, and trees.

Insulin is one of the significant hormones in the human body. The information about insulin and its mechanisms explains how the human body uses food for its energy requirements.
Generally, glucose obtained from the food that travels in the bloodstream is responsible for elevating the blood sugar level. The pancreas is an organ that helps in releasing insulin for controlling the blood glucose level. Insulin tends to get released in a feedback mechanism depending on the blood sugar level.
The mechanism of insulin best demonstrates the following:
Thus, the mechanism of insulin in the human body explains how energy is utilized by different cells and how insulin is important in maintaining homeostasis.
