Because wen population is dity
It teaches us how to spell.
Mass and distance.
Indicator species can be used in one of two ways: * the indicator species is one which easily affected by the pollutant. Specimens are kept in an area and observed. When they show distress the pollution rate is climbing, and this happens before the hardier species are impacted. Think of canaries in coal mines. * When a biologist inspects an ecosystem he keeps track of the population and the species present. If only hardy (pollution resistant) species are present the ecology has become degraded. If sensitive species are present the environemt is still good.
lack of food a and our pollution
Invasive species...........pollution

pollution, littering, etc.
Pollution can have a detrimental effect on endangered species by contaminating their habitat, leading to health issues, reduced reproductive success, and even death. Pollutants like chemicals, plastics, and heavy metals can disrupt the ecosystem balance and threaten the survival of already vulnerable species. Efforts to reduce pollution are crucial in protecting endangered species and their habitats.
There are currently too many insect species at risk because of pollution.
Biological indicators for air pollution include lichens, mosses, and certain tree species that show sensitivity to pollutants like sulfur dioxide and heavy metals. Additionally, the health of sensitive species like bees, butterflies, and amphibians can also indicate air pollution levels. Changes in biodiversity and population sizes of these species can provide valuable insights into the impacts of air pollution on ecosystems.
Yes.Because of pollution.
All of them
