Impacts on Ecosystems Flashcards
How do bushfires affect ecosystems?
Bushfires can cause habitat loss and decrease water and air quality, but they can also promote germination and flowering in some species.
How does drought affect ecosystems?
Drought can alter water availability, leading to habitat loss, increased wildfire risk, and changes in plant and animal populations.
How does flooding affect ecosystems?
Flooding can destroy habitats, spread diseases, and cause animals and plants to drown from lack of oxygen.
How does habitat destruction affect ecosystems?
Habitat destruction leads to biodiversity loss, disrupts food webs, and increases extinction risks.
How do introduced species affect ecosystems?
Introduced species compete with native species for resources, disrupt food webs, and potentially introduce diseases, leading to biodiversity loss and altered ecosystem processes.
How do chemical pesticides affect ecosystems?
Chemical pesticides can accumulate in organisms and increase along food chains, leading to biodiversity loss and disruption of food chains.
How does chemical pollution affect ecosystems?
Chemical pollution involves toxic chemicals escaping into the environment, causing harm to organisms and potentially leading to biodiversity loss and ecosystem degradation.
How does overcropping affect ecosystems?
Overcropping results in more animals being killed than can be replaced by the normal breeding cycle, leading to disruption of food chains and extinction of animals.
