A discussion on the ecosystems as energy flow systems

Energy has been defined as the capacity to do work. Energy exists in two forms potential and kinetic. Kinetic energy is the energy of motion free energy. It results in work performance at the expense of potential energy.

Conversion of potential energy into kinetic energy involves the imparting of motion. The source of energy required by all living organisms is the chemical energy of their food.

The chemical energy is obtained by the conversion of the radiant energy of sun. The radiant energy is in the form of electromagnetic waves which are released from the sun during the transmutation of hydrogen to helium. The chemical energy stored in the food of living organisms is converted into potential energy by the arrangement of the constituent atoms of food in a particular manner.

In any ecosystem there should be unidirectional flow of energy. This energy flow is based on two important Laws of Thermodynamics which are as follows: It states that the amount of energy in the universe is constant. It may change from one form to another, but it can neither be created nor destroyed.

Light energy can be neither created nor destroyed as it passes through the atmosphere. It may, however, be transformed into another type of energy, such as chemical energy or heat energy. These forms of energy cannot be transformed into electromagnetic radiation. It states that non-random energy mechanical, chemical, radiant energy cannot be changed without some degradation into heat energy.

The change of energy from one form to another takes place in such a way that a part of energy assumes waste form heat energy. In this way, after transformation the capacity of energy to perform work is decreased.

Thus, energy flows from higher to lower level. Main source of energy is sun.

A discussion on the ecosystems as energy flow systems

Energy flow in Ecosystems: Living organisms can use energy in two forms radiant and fixed energy. Radiant energy is in the form of electromagnetic waves, such as light. Fixed energy is potential chemical energy bound in various organic substances which can be broken down in order to release their energy content.

Organisms that can fix radiant energy utilizing inorganic substances to produce organic molecules are called autotrophs. Organisms that cannot obtain energy from abiotic source but depend on energy-rich organic molecules synthesized by autotrophs are called heterotrophs.

Those which obtain energy from living organisms are called consumers and those which obtain energy from dead organisms are called decomposers Fig. When the light energy falls on the green surfaces of plants, a part of it is transformed into chemical energy which is stored in various organic products in the plants.Essay on Ecosystem | Environment.
