Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
What 2 factors can affect the biodiversity present in an area?
Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches. Which human activities threaten biodiversity? Human activities can also threaten biodiversity.
What are the factors affecting biodiversity?
Major threats to biodiversity are:
- Habitat destruction/Deforestation.
- Introduced and invasive species.
- Genetic pollution.
- Over exploitation.
- Climate change.
- Human over-population.
How does location affect biodiversity?
Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species. In addition, many species require a large range for adequate prey or seed forage.
What are the two most harmful factors to biodiversity?
The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.
Which affects biodiversity the most?
Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity.
What are the main factors that lead to biodiversity loss in urban areas?
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 cause of biodiversity and destruction?
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
What are the factors that affect the biodiversity in India?
The biodiversity of any place is affected by the following factors such as the climate change and the deforestation and the overgrazing and invasion of species and also is affected by the levels of the pollution the rates of the poaching of the wildlife species and thus these factor are related to the destruction of …
How does Habitat change affect biodiversity?
Habitat loss has significant, consistently negative effects on biodiversity. Habitat loss negatively influences biodiversity directly through its impact on species abundance, genetic diversity, species richness, species distribution, and also indirectly.
How does limiting factors affect biodiversity?
In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. … Sometimes a population will grow too large for the environment to support.
How does Island area affect diversity?
The more isolated an island is, the lower its species richness will be. An island’s size also affects its biodiversity, since larger islands will have a wider variety of habitats, so species which arrive on the island will diversify to fill up the available niches.
What is biodiversity and its threats?
Threats to Biodiversity. The greatest threat leading to the loss of biodiversity is the human race. As our population grows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural ones.
Which of the following can be threats to the biodiversity of a geographical area?
Global Warming, fragmentation of habitat and invasion of alien species can be threats to the biodiversity of a geographical area.
