Economic value is defined as the value a person attaches to something, could be a commodity, a service, etc., based on the benefits they derive from it. This value is often demonstrated by the person’s willingness to pay a certain amount of money (because it is economic) to have such goods or services. The more […]

Biology, Class 12, Ecology and Environment, Ecosystem: Structure, function, productivity, energy flow, NEETBiodiversity consists of two words, bio, which means life, and diversity, which means a wide( variety). Biodiversity can be defined as a huge batch of species of germs, algae, fungi, grains and creatures occurring on the planet, either in territorial or oceanic habitats and ecological networks . Biodiversity is the occurrence of different types of

Biology, Class 12, Ecology and Environment, Ecosystem: Structure, function, productivity, energy flow, NEETPlants are the most important things in our ecology. It plays an important role in maintenance of balance within the ecosystem. They provide oxygen in the earth’s environment and utilise carbon dioxide from the environment. After the industrial revolution, deforestation can be observed worldwide. All these are impacting the environment negatively resulting in global warming,

Biology, Class 12, Ecology and Environment, Ecosystem: Structure, function, productivity, energy flow, NEETThe study of animal science is known as zoology. It is a branch of biology that studies the life of animals, the structure of their organisms, and the subcellular life units that make them up. In the field of zoology, scientists investigate the functioning and structure of animal bodies, as well as the formation of
A symbiotic interaction between two species is described by both commensalism and mutualism. The major distinction is whether one or both organisms’ profit from the association. Mutualism is further separated into two types, depending on how reliant organisms are on one another for existence. Symbiosis In an environment, symbiosis refers to a variety of living

Biology, Class 12, Ecology and Environment, NEET, Organisms and populations: Ecological adaptations, population interactionsThis brings us to our first frequently misunderstood term. The build-up of a harmful substance in the body of a live organism is known as bioaccumulation. What happens is that the chemicals are absorbed through the skin or otherwise taken in by the body. Biomagnification, which occurs when a harmful chemical rises in amount as

Biology, Class 12, Ecology and Environment, NEET, Organisms and populations: Ecological adaptations, population interactionsAn organism is a particular living species that exhibits all of the characteristics of life. A bird, plant, animal, insect, or even a microorganism can be one of these. On our planet Earth, there seem to be billions to trillions of various kinds of species. All of these organisms are divided into categories based on a variety

Biology, Class 12, Ecology and Environment, NEET, Organisms and populations: Ecological adaptations, population interactionsThe term “environment” refers to everything that is around us and has an impact on our growth and development. The environment is made up of both live and nonliving entities. As a result, we can divide the atmosphere into two categories: physical or abiotic and biological or biotic. Temperature, light, soil, air, and water are

Biology, Class 12, Ecology and Environment, NEET, Organisms and populations: Ecological adaptations, population interactionsINTRODUCTION An ecosystem is a term that is used a lot in biology and environmental studies. A system or community that includes all living things and their non-living parts in nature is called a “system” or a “community.” Ecological balance is the result of all of these parts working together in some way. So, it

Biology, Class 12, Ecology and Environment, NEET, Organisms and populations: Ecological adaptations, population interactionsThe trophic levels of a food chain are divided into several categories. These trophic levels are used to distinguish between different types of organisms. After producers, primary consumers, and secondary consumers, a tertiary consumer is the fourth trophic level in the food chain. Consumers in the tertiary sector eat primary and secondary consumers as their
