The four major components of biological diversity are: Functional Diversity (biological or chemical processes such as energy flow and matter recycling needed for the survival of species, communities, and ecosystems), Ecological Diversity (the variety of terrestrial and aquatic ecosystems found in an area or on the …
What are the main components of biodiversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
What 4 major factors are contributing to the loss of biodiversity?
CAUSES OF BIODIVERSITY LOSS
- Climate change.
- Destruction of habitats.
- Invasive alien species.
- Overexploitation of the natural environment.
- Extinction of species.
- Threat to human beings.
- Proliferation of pests.
What are the 4 main factors that can affect ecosystems and its biodiversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
What are the 4 benefits of biodiversity?
The four key benefits are: (1) Biodiversity Provides the Natural Resource, (2) Biodiversity Provides the Genetic Resource, (3) Biodiversity Maintains a Stable Ecosystem, and (4) Biodiversity Ensures Optimum Utilization and Conservation of Abiotic Resources in an Ecosystem.
What are the four major components of biological diversity What is the importance of biodiversity?
The four major components of biodiversity are species diversity, ecological diversity, genetic diversity, and functional diversity. Biodiversity is important because it allows for organisms to adapt to their environment, and to survive dramatic environmental changes.
How many components are there in the species diversity?
There are three main components of species diversity, species richness and relative abundance.
What are the 5 factors that affect biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What are the 5 major causes of biodiversity loss?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming.
What are the biotic components in high biodiversity?
The biodiversity in ecosystems is affected by the following three factors: Biotic: Biotic factors are the interactions between the living things in an ecosystem. This can include grazing and predation. Animals which graze on the plant species in an ecosystem can influence which species of plants can survive.
What are the three factors of biodiversity?
Biodiversity is an abbreviation for biological diversity. It generally means the ‘diversity of flora and fauna (plants and animals)’ (IB definition). It has three factors, ecosystem, species and genetics.
What are the components of biotic?
Biotic components include plants, animals, decomposers. Nonliving components include air, water, land.
The biotic component of an ecosystem has been classified into three groups:
- Producers (green plants)
- Macro consumers (usually animals)
- Micro consumers or decomposers (organisms like bacteria and fungi).
