Gaps include: species diversity, micro-organisms and their ecological roles, ecological and geographical status of species, human capacity to assess and forecast bio-ecological degradation.
What are the 5 main reasons for biodiversity decline?
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 three factors that affect biodiversity?
Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches.
What are the 3 types of diversity that make up 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 is the greatest cause of biodiversity loss today?
Habitat alteration-every human activity can alter the habitat of the organisms around us. Farming, grazing, agriculture, clearing of forests, etc. This is the greatest cause of biodiversity loss today.

What is the difference between the three types of biodiversity?
Biodiversity occurs in three different levels: Genetic, Species, and Ecosystem. Genetic diversity refers to the differences within members of a species and their ability to adapt to changes. Species diversity refers to the total number of plant, animal, and insect species that can be found in a particular region.
How does declining biodiversity affect us?
Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply. For humans that is worrying.
How biodiversity is affected and endangered by human activities?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
