It is the entire pool from which a statistical sample is drawn from a different group of individuals.

It refers to an entire group of people of different races, sexuality, and status; objects like
material things; events like social gatherings; hospital or school visitations, and
measurements of a distinct boundary.

Q

These resources include minerals, plants, water, and wildlife, particularly in the oceans, as well as fossil fuels (oil, gas, and coal). In turn, the removal of resources
frequently results in the release of trash and toxins that degrade the quality of the air and water and endanger the health of both humans and other species

Q

To build urban areas, including homes, shops, and highways to accommodate expanding populations,
forests and other habitats are uprooted or destroyed. In addition, when populations rise, more land is
put to use for farming, including raising crops and caring for animals. This in turn has the potential to
reduce species populations, geographic ranges, biodiversity, and change how organisms interact with
one another.

A

Q

Which is reducing the numbers of the exploited species. If additional resources are made available for
the species that remain in the environment, fishing and hunting may also indirectly boost the numbers
of species that are not fished or hunted.

Which increases the spread of invasive species. Invasive species frequently thrive in
disturbed habitats where urbanization has occurred and outcompete native
species. For instance, numerous invasive plant species abound in the areas of
land near to highways and roadways.
