What is biodiversity Why is diversity?
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.
Why is species diversity important to biodiversity?
Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. … A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.
What is meant by species diversity?
Species diversity is the number of different species that are represented in a given community (a dataset). … Taxonomic or phylogenetic diversity is the genetic relationship between different groups of species. Species evenness quantifies how equal the abundances of the species are.
What are 3 Reasons why biodiversity is important?

How are species diversity and genetic diversity different?
How are species diversity and genetic diversity different? Species diversity measures the number of species in the biosphere, while genetic diversity measures the variety of genes in the biosphere, including genetic variation within species. … many habitats and species are at high risk of extinction.
What is biodiversity and why is it important for an ecosystem?
Biodiversity is a measure of variation at genetic, species and ecosystem levels. It helps to boost the ecosystem and its productivity where every species have a meaning and a role no matter how small. For example, a large number of plant species mean a great variety of crops.
Why is sustainable biodiversity important?
Biodiversity is essential for sustainable development and human well-being. It underpins the provision of food, fibre and water; it mitigates and provides resilience to climate change; it supports human health, and provides jobs in agriculture, fisheries, forestry and many other sectors.
Why is functional diversity important?
Functional diversity is of ecological importance because it, by definition, is the component of diversity that influences ecosystem dynamics, stability, productivity, nutrient balance, and other aspects of ecosystem functioning.
Why is biodiversity more advantageous than low biodiversity?
High biodiversity in an ecosystem means that there is a great variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.”
How can you say species diversity affect biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
