Biodiversity is a large word for a term describing the rich diversity of life on this planet. Since life began on Earth it has been evolving each species into a more complex form. Life has been able to become so diverse because of the unique adaptations of different species for survival in their environment. This […]

Agro-biodiversity can be defined as the diversity of crops consumed by humans for their livelihoods. Another term to define agro-biodiversity is ‘agricultural biodiversity. The main reason behind introducing this term is that, the use of biodiversity products in human diet and medicine through cultivation and natural resources is known as agriculture and not simply bio-diversity.

All species provide some kind of function to an ecosystem. They can capture and store energy, produce organic material, decompose organic material, help to cycle water and nutrients throughout the ecosystem, control erosion or pests, fix atmospheric gases, or help regulate climate. Some species even play multiple roles within an ecosystem. Species capture and store

Biodiversity is the variety of life on Earth and we human beings, we directly depend on biodiversity to survive. Biodiversity helps to maintain balance in the natural world and prevents living organisms from becoming extinct. It also provides a variety of food and other resources like building materials, medicines and other materials for our use

Biodiversity encompasses the variety and variability of life on Earth. It is a measure of the number of different species, genes, ecosystems or habitat types in an area. The greater the biodiversity, the more efficient the ecosystem in providing nutrients, decomposing wastes, regulating climatic conditions, etc. Biodiversity can be discussed at three levels (i) Genetic

Biodiversity is the branch of biology that deals with the diversity within species, between species and in ecosystems. Biodiversity is essential to ecosystem functioning and human well-being. It provides food, fiber, medicines, clean water and fresh air. It helps regulate water cycles and climate patterns, including rainfall. The loss of biodiversity also creates the conditions

The organisms and habitat together form what we call an ecosystem. Ecosystems can vary greatly in size. From tiny microorganisms to large landscapes, ecosystems allow the earth’s living things to survive and thrive. Ecological balance is a state of dynamic equilibrium within a community of organisms in a habitat or ecosystem. Dynamic means that there

The biogeochemical cycles of the biosphere relate to essential processes that take place within and between the major cells and organisms that make up living systems and that alter and shape them. The word biogeochemical also implies the integration of the biological, geological, and chemical aspects of those cycles. Biogeochemical cycles involve both organic and

Food chains are essentially a process of energy transfer. Cells, at the base of the chain, convert light into chemical energy. During photosynthesis, plant cells produce glucose to use for energy and for the production of more complex compounds. Herbivores eat autotrophs, while carnivores eat herbivores. The detrital food chain begins with dead organic matter.

The ecosystem consists of living organisms and non-living elements in a particular environment. The ecosystem can be a terrestrial or aquatic ecosystem. The terrestrial ecosystem includes interaction between the species in the terrestrial region whereas the aquatic one includes species living in water bodies. The ecosystems are present everywhere in our surroundings though they are
