What is the role of energy in living organism? Is it more or less important role than other characteristic of life?
The role of energy in the living organism is very important and vital to the survival of the biotic community in which
1. It lets them function in daily activities
2. It is the source as to why organisms can move, respire, sense, excrete, maintain homeostasis and reproduce.
3. In a cellular perspective, energy by many organism formed by the mitochondria for other organelles to do their function such as manufacture, process and pack enzymes needed for certain cellular operations.
The Role of Energy in Living Organisms
Energy is indispensable in the life of organisms, as it is the capacity to do work or induce change. It is critical for various processes such as growth, reproduction, and maintenance of cellular structures. Living things require a constant input of energy for metabolic processes, like the synthesis of complex molecules from simpler ones, which is essential for maintaining life's complex order against the natural tendency towards disorder.
There are two main types of energy: potential energy , which is stored energy, and kinetic energy , which is energy in motion. The main difference between the two is that potential energy represents stored capabilities to perform work, whereas kinetic energy is the actual execution of work.
The original source of most energy used by living organisms on Earth is the sun. Through photosynthesis, plants capture solar energy and convert it into chemical energy. Heterotrophic organisms, such as animals and humans, obtain their energy secondarily by consuming plants or other organisms.
Energy is essential for all living organisms as it fuels vital processes like metabolism, growth, and homeostasis. While other life characteristics are important, the absence of energy would halt these functions. Therefore, energy is a fundamental requirement for life.
