What is biodiversity Why is biodiversity important for human lives Brainly?
Answer: Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What are other factors affecting biological diversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7). No single measure or indicator represents the totality of the various drivers.
What is diversity in biology class 11?
Every living organism is unique with respect to structure, body functions, genetic make-up and so on. … Different types and classes of organisms inhabiting different environments is known as biodiversity. Regions that are warm and humid have more diverse organisms and are called mega-biodiversity.
Explanation: Biodiversity is a measurement of how many different types of organisms are found in an ecosystem. The higher the biodiversity means that the ecosystem can sustain (maintain) many different types of producers, consumers, and decomposers. This generally means that the area is healthy.
What is species diversity in biology?
Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth). Species are the basic units of biological classification and hence, this is the measure most commonly associated with the term ‘biodiversity’.
