Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction. … Genetic Diversity is the diversity of genetic characteristics (expressed or recessive) within a species (i.e. between individuals and populations of the same species).
What do you mean by biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What are the differences between ecosystem diversity species diversity and genetic diversity?
The main difference between genetic diversity and species diversity is that genetic diversity is the differences of DNA among individuals of a particular species whereas species diversity is the variety of species in a particular region. Ecological diversity is the variety of ecosystems in a particular area.
What is biodiversity and ecosystem?
Ecosystem biodiversity refers to the variety of ecosystems, by their nature and number, where living species interact with their environment and with each other. For example, on Earth, there are different ecosystems, each with their specificities like deserts, oceans, lakes, plains or forests.
What is ecosystem diversity explain?
Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. … An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans.
What is biodiversity short answer?
Biodiversity can be described as the sum total of all plants and animals found in a particular area. It is basically a measure of all variations found at the genetic, species, and ecosystem level. It is mainly influenced by the environmental, geographical, climatic and topographical conditions of an area.
What diversity means in biodiversity?
‘Biological diversity’ means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.
What is biodiversity explain genetic diversity with suitable example?
Biodiversity is the variety of plants and animals inhabiting in an ecosystem. It includes species diversity, genetic diversity and ecosystem diversity. Genetic diversity is defined as genetic variability present within species.
What are the differences between biodiversity and ecosystem?
Biodiversity is the biological variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact.
What is biodiversity types of biodiversity?
Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).
What is biodiversity with example?
Biodiversity is the variety of life. … Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
What is biodiversity class 9?
Answer: Biodiversity is a place where all the living organisms live interacting with the lithosphere land hyrosphere and atmosters.
What is biodiversity class 11?
In simple terms, biodiversity is the number and variety of organisms found within a specified geographic region. … It relates to the variability among living organisms on the earth, including the variability within and between the species and that within and between the ecosystems.
What is ecosystem diversity class 10?
Answer: Ecosystem diversity deals with the variations in ecosystems within a geographical location and their overall impact on human existence and the environment. It is a type of biodiversity which refers to variation in species rather than ecosystems.
What is ecosystem diversity class 8?
The diversity within the ecosystem is called ecosystem diversity. Therefore, the diversity of habitats and life are formed within the system. … In Nepal, there are all types of ecosystems except desert and ocean ecosystems found in the world.
What is ecosystem diversity class 12?
(c) Ecological diversity is the diversity at ecosystem level. For example, India with its deserts, rain forests, mangroves, coral reefs, wetlands, estuaries and alpine meadows has a greater ecosystem diversity. 2. Global species diversity means total species present on the earth.
