populations of different species

Species - The sum of all the populations of same kind of organisms all over the world is called species. Generally, a species is often defined as a group of organisms similar in structure, function and behaviours. But there are numerous examples where the mem..

The double bar graph shows the population growth of two bird species during four consequent quarters. Find the difference between the average growth of the two species. => 10 thousands or 5 thousands or 30 thousands or 20 thousands..

Species is generally the lowest taxonomic rank representing organisms that are very much closely related to one another. A species is defined as a group of closely related, structurally and functionally similar organisms which can breed among themselves, producing fertile offspr..

Their population is still abundant but their habitat is adversely affected. They may become endangered if their habitat continues to be affected. Examples: Leopard and golden lang..

Both genus and community are formed of many species. But the two differ from each other in some basic characters. Species in a genus have a common ancestry. They occur in different geographical regions and often have no functional relation or interaction amo..

Population and Its Characteristics - Population is the next level in ecological hierarchy the word population has its origin in the Latin word populus meaning 'people'. In ecology, population is defined as the total number of all individuals of a particular h..

Individuals living in the same area are referred as local populations. They all experience similar ecological processess at a particular stage of the life cycle. Similar populations of a species occupying different geographical areas are called sister po..

These are species with small populations in the world. They are confined to limited areas or are thinly distributed over a more wide area. They are not at present endangered and vulnerable but are at risk. Example: Two species of Asiatic pheasa..

A species is a group of similar organisms, which can breed among themselves producing fertile offsprings. The members of a species not only share a common gene pool, but also share a common ancestry. Origin of a new species from the existing one, is called speciation. ..
