BIOGEOCHEMICAL CYCLES
There is a circulation of chemical nutrients like oxygen, carbon, nitrogen, phosphorus, calcium, and water, etc. through the physical and biological world; between the atmosphere, hydrosphere, lithosphere, and biosphere. These cycles are known as biogeochemical cycles. These cycles are natural pathways of the circulation of essential elements of life. For the survival of the major… Continue reading BIOGEOCHEMICAL CYCLES
What are the Trophic Levels?
Each organism occupies a particular position in a food chain depending on its feeding relationship with other organisms. This position is known as the trophic level. It is important to note that the amount of energy decreases at successive trophic levels. When an organism dies it is converted to detritus. It then serves as an… Continue reading What are the Trophic Levels?
Ecological Pyramids
Ecological pyramids are the diagrammatic representations of the feeding relationship and energy transfers in the ecosystem. They are of three types: Pyramid of Numbers, Pyramid of Biomass and Pyramid of Energy. Pyramid of Numbers: It represents the relationship between number of individuals of primary producers and consumers at different trophic levels. It can be upright… Continue reading Ecological Pyramids
How does the Energy Flow in an Ecosystem?
In simplest terms, the behaviour of energy in an ecosystem is called energy flow. The flow of energy in the ecosystem is always unidirectional (linear). The energy flow obeys the first and second law of thermodynamics. Laws of Thermodynamics (Rudolf Clausius and William Thomson) 1st Law: Energy cannot be created or destroyed but can be… Continue reading How does the Energy Flow in an Ecosystem?
Food chains and Food webs
Food Chains A food chain describes how energy and nutrients move through an ecosystem. It basically shows who eats what in the ecosystem. Thus, the transfer of energy from the source in plants through a series of organisms by eating and being eaten constitutes food chains. At each transfer, a large proportion of energy is… Continue reading Food chains and Food webs

Ecological niche
The term ecological niche was developed by Charles Elton. Ecological niche may be defined as ‘the functional role and position (micro-habitat) of species in its ecosystem, including what resources it uses, how and when it uses the resources, and how it interacts with other species. The ecosystem stability depends upon the diversity of the niche.… Continue reading Ecological niche
