Threats to biodiversity

Front

What is overharvesting?

Back

Overharvesting refers to catching or removing more aquatic animals or plants than the population can replace, leading to a decline in species.

Front

What are invasive species?

Back

Invasive species are non-native species that are introduced to an ecosystem and can outcompete native species for resources, often disrupting the local ecosystem.

Front

What is habitat destruction?

Back

Habitat destruction is the process in which natural habitats are rendered unable to support the species present, often due to human activities like deforestation, urbanization, and pollution.

Front

What is a trophic cascade?

Back

A trophic cascade is an ecological phenomenon triggered by the addition or removal of top predators, which leads to dramatic changes in ecosystem structure and nutrient cycling.

Front

What is the impact of global warming on biodiversity?

Back

Global warming can lead to habitat loss, altered species distributions, and increased extinction rates, threatening overall biodiversity.

Front

What does 'sustainable fishing' mean?

Back

Sustainable fishing refers to practices that maintain fish populations and the health of the marine ecosystem, ensuring that fish can reproduce and thrive.

Front

What is the role of native plants in an ecosystem?

Back

Native plants are adapted to the local environment and provide essential habitat and food for local wildlife, contributing to ecosystem stability.

Front

How do non-native plants threaten native species?

Back

Non-native plants can threaten native species by competing for resources such as light, water, and nutrients, often leading to the decline of native populations.

Front

What is aquaculture?

Back

Aquaculture is the farming of aquatic organisms, such as fish, crustaceans, and plants, in controlled environments for food production.

Front

What are the consequences of overgrazing?

Back

Overgrazing can lead to soil degradation, loss of plant cover, and increased erosion, negatively impacting the ecosystem.
