Q&A
What are the man-made causes of extinction?
Man-made causes of extinction include deforestation due to activities such as kaing, farming, illegal logging, and forest fires, water pollution from eutrophication, air pollution, and coastal resource destruction from activities like mining, dynamite fishing, and overharvesting.
How do invasive species contribute to extinction?
Invasive species increase competition for resources, leading to the extinction of natural species. They are a significant factor in man-made causes of extinction, which also include deforestation, water pollution, and coastal resource destruction.
What are the natural causes of extinction?
Natural causes of extinction include extreme heating and cooling, changes in sea level, volcanic activity, cosmic radiation, acid rain, and diseases, which lead to a decline in populations and weaken gene pools.
What challenges do populations face related to sustainability?
Populations face challenges related to sustainability, such as competition for resources, endangerment, and extinction.
What factors affect population distribution?
Factors affecting population distribution include protection from predators, hunting processes, random distribution, geographic factors, social and economic factors, and demographic factors.
What is population density and distribution?
Population density refers to the number of individuals per unit area, while population distribution can be uniform, clumped, or dispersed.
How does biodiversity support ecosystem stability?
Biodiversity is crucial for providing clean water, fresh air, food, medicine, and other resources. It allows ecosystems to adapt to environmental changes and supports the interdependence of organisms.
What are the components of biodiversity?
Biodiversity consists of species diversity, genetic diversity, and ecosystem diversity. Species diversity refers to the variety of different species, genetic diversity entails variation in genes within a species, and ecosystem diversity involves variations among groups of organisms in different environments like terrestrial, freshwater, and marine ecosystems.
What is biodiversity and why is it important?
Biodiversity encompasses species diversity, genetic diversity, and ecosystem diversity, playing a key role in maintaining a healthy environment, providing resources, and enabling ecosystems to adapt to environmental changes.
- 00:13 Biodiversity is essential for maintaining the balance in the ecosystem, but human activity is causing a decrease in the number of species, leading to extinction. Biodiversity includes species diversity, genetic diversity, and ecosystem diversity.
- 02:06 Biodiversity encompasses species diversity, genetic diversity, and ecosystem diversity, which all play a key role in maintaining a healthy environment and providing various resources. It enables ecosystems to adapt to environmental changes and supports the interdependence of organisms.
- 04:19 Biodiversity is important for environmental adaptability, population density is the number of individuals per unit area, and population distribution can be uniform, clumped, or dispersed.
- 06:15 Different factors affect population distribution such as protection from predators, hunting processes, random distribution, geographic factors, social and economic factors, and demographic factors. Populations can face challenges related to sustainability, competition for resources, and the risk of endangerment or extinction.
- 08:17 Extinction can be caused by natural factors like climate change, sea level fluctuation, volcanic activity, cosmic radiation, acid rain, and diseases, leading to a decline in populations and weakening gene pools.
- 10:06 Invasive species and man-made causes of extinction can lead to competition for resources and environmental destruction. Deforestation, water and air pollution, and coastal resource destruction are key issues.
