Some theorists are saying pigeons. You know like city pigeons? Well That is what they are saying
Biological indicators are species used to monitor the health of an environment or ecosystem.
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.
Pollution indicators can include changes in air quality, such as high levels of particulate matter or ozone. Water pollution indicators may involve elevated levels of contaminants like heavy metals or bacteria. Biological indicators like the presence of certain species can also signal pollution in an ecosystem.
Comparision of mhoperlogical And biological species concept
Biological species consists of groups of populations. Populations are assigned to the same biological species based on their ability to interbreed and produce fertile (viable) offspring.
Species (under the Biological Species Concept).
The Biological Species Concept identifies species based on the absence of interbreeding and the presence of reproductive isolation mechanisms. This concept defines a species as a group of organisms that can interbreed and produce fertile offspring.
Biological
According to the biological species concept, two organisms are of different species if they do not do which of these
The basic biological unit in the Linnaean system of biological classification is the species. It is the fundamental category for classifying living organisms based on shared characteristics and reproductive compatibility.
A biological population consists of all one species instead of many species.
The biological characteristic that defines females across species is the presence of two X chromosomes.
