What are ecological services?

Back

Ecological services are the benefits that humans derive from ecosystems, including services like pollination, water purification, and erosion control.

Front

What is an invasive species?

Back

An invasive species is an organism that thrives in a new territory where it is free of predators, diseases, or resource limitations that may have controlled its population in its original habitat.

Front

What is ecological diversity?

Back

Ecological diversity measures the richness and complexity of a biological community, including the variety of ecosystems and habitats.

Front

What are the main threats to biodiversity?

Back

Main threats to biodiversity include habitat destruction, pollution, invasive species, and overharvesting.

Front

What is the role of keystone species in an ecosystem?

Back

Keystone species are organisms that have a disproportionately large effect on their environment relative to their abundance, helping to maintain the structure of an ecological community.

Front

What is the significance of wild insect pollinators?

Back

Wild insect pollinators are crucial for the pollination of many crops, and most of the world depends on them for food production.

Front

What is overuse and degradation in the context of national parks?

Back

Overuse and degradation refer to the excessive use of natural resources in national parks, leading to environmental damage and loss of biodiversity.

Front

What is species diversity?

Back

Species diversity refers to the variety of different species within a given ecosystem, including the number of species and their relative abundance.

Front

What is genetic diversity?

Back

Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, which is important for the adaptability and survival of the species.

Front

What are flagship species?

Back

Flagship species are species that are used as symbols or ambassadors for a particular habitat, often to raise awareness and support for conservation efforts.
