Concept explainers
To describe:
The threats of habitat destruction, overexploitation, invasive species, pollution, and global climate change.
Introduction:
Biodiversity is a habitat where entire living organism lives together. It is of three types: species biodiversity, genetic biodiversity, and ecosystem biodiversity.
Habitat destruction, overexploitation, invasive species, pollution, and global climate change are the threats to biodiversity.
Habitat destruction occurs due to human activities like urbanization, deforestation, and overhunting; due to these activities species lose their habitat.
Overexploitation occur when humans start over harvesting the species; for example, over hunting and over fishing,
Invasive species are not native to the ecosystem and cause harm to other existing species are called invasive species; it can be anything plant, insects, or fish.
Pollution it is of many types; for example, soil pollution, air pollution, and water pollution. It is caused by humans and affects biodiversity.
Global climate change occurs due to overharvesting of species, and pollution, ecosystem starts to imbalance, which cause changes in the climate called global climate change.

- Describe any three ways in which invasive species may impact biodiversity.arrow_forwardWhat are the variables for sustainability for species diversity?arrow_forwardEnvironmental scientists David Pimentel, Rodolfo Zuniga, and Doug Morrison of Cornell University reviewed scientific estimates for the economic and ecological costs imposed by introduced and invasive species in the United States. They found that, as of 2005, approximately 50,000 species had been introduced in the United States and that these accountedfor over $120 billion in economic costs each year. These costs include direct losses and damage, as well as costs required to control the species. (The researchers did not quantify monetary estimates for losses of biodiversity, ecosystem services, and aesthetics, which they said would drive total costs several times higher.) Calculate values missing from the table to determine the number of introduced species of each type of organism and the annual cost that each imposes on our economy. Of the 50,000 species introduced into the UnitedStates, half are plants. Describe two ways in whichnon-native plants might be brought to a new location.How…arrow_forward
- Why Preserve Biodiversity?arrow_forwardWhat is the single greatest threat to biodiversity?(A) overharvesting of commercially important species(B) habitat alteration, fragmentation, and destruction(C) introduced species that compete with native species(D) novel pathogensarrow_forwardWhich of the following statements about keystone species is false? a) Keystone species are the most common (abundant) species in their ecosystem. b) The reintroduction of wolves into Yellowstone Park increased biodiversity. c) Removal of a keystone species can drastically change an ecosystem. d) Keystone species have a much greater effect on the functioning of their ecosystems than other species.arrow_forward
