Threats to biodiversity

Front

What is an invasive species?

Back

An invasive species is a non-native species that spreads widely in a new habitat and has no natural predators, leading to potential harm to the ecosystem.

Front

What are the effects of global warming?

Back

The effects of global warming include rising sea levels, melting of ice caps, increased frequency of extreme weather events, and changes in wildlife habitats.

Front

What is the primary source of air pollution?

Back

The primary source of air pollution is human activities, including industrial emissions, vehicle exhaust, and burning fossil fuels.

Front

What does overharvesting refer to?

Back

Overharvesting refers to catching or removing more aquatic animals or plants than the population can naturally replace, leading to depletion of species.

Front

Which of the following is NOT a cause for the decline in biodiversity?

Back

Regenerating forests is NOT a cause for the decline in biodiversity; in fact, it can help restore ecosystems.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What are some human activities that threaten biodiversity?

Back

Human activities that threaten biodiversity include deforestation, pollution, urbanization, and climate change.

Front

How does habitat destruction impact biodiversity?

Back

Habitat destruction leads to loss of species, fragmentation of ecosystems, and reduced genetic diversity, ultimately threatening the survival of many organisms.

Front

What role do protected areas play in biodiversity conservation?

Back

Protected areas help conserve biodiversity by providing safe habitats for species, preserving ecosystems, and allowing for natural processes to occur.

Front

What is the significance of keystone species in an ecosystem?

Back

Keystone species are crucial for maintaining the structure of an ecosystem; their removal can lead to significant changes and loss of biodiversity.
