The faculty of the College believe that a sound knowledge of biology is essential for understanding the world in which we live, engaging many pressing problems facing humanity, and becoming a part of their eventual solution. The Biological Sciences Collegiate Division, therefore, provides a variety of general education courses for all College students—prospective biologists and non-biologists alike. Although most of the course offerings beyond the introductory year are designed to serve the needs of students majoring in biological sciences, many of these courses are well suited to students in other areas who wish to study some aspect of modern biology in greater detail. Courses on the ethical and societal implications of the biological sciences, for example, are of interest to many non-majors.
The term biological diversity or biodiversity refers to the variety of life forms and habitats found in a defined area.
Ashford SCI Entire Course Dependence of Man on the Environment h. Essay about Biomes and Diversity Biomes and Diversity The importance of Biomes is regulated and should be preserved by the environment for which any particular organism is located. The ecosystems composed in relation to the Biomes differ from region to region so a controlled system most be established to balance the growth of dominant inviters. The table below presents an abbreviated geologic time scale, with times and events germane to this essay. Please refer to a complete geologic time scale when this one seems inadequate.
The term biodiversity was coined by W. Diversity characterizes most living organisms, the our earth supports something like 5 to 10 million species of plants and animals IUCN, which have been the result of 3 billion years of evolution involving mutation, recombination and natural selection. Biodiversity is an umbrella term covering diversity at genetic, species and ecosystem level.
Levels or Components of Biodiversity: Biodiversity is said to have three hierarchical levels, or components: The diversity of ecological complexes or biotic communities found in a given area.
Indian ecosystem diversity is described at each of the three levels biogeographical region, biotic province and biome. Largest of identified ecosystems has been the biogeographical zone.
The vast area covered by biogeographical zone contains a wide diversity of smaller units called biotic provinces. Finally, within each biotic province, various kinds of biomes are distinguished.
Biome classification broadly follows commonly used terminology, distinguishing between forests, grasslands, wetlands, deserts, and other such ecosystems on the basis of their physical appearance and dominant biotic or abiotic element.
The enormous range of terrestrial and aquatic environments on earth has been classified into number of ecosystems.
Ecosystems differ not only in the species composition of their communities but also in their physical structures including the structures created by organisms.
Species diversity refers to variety of species in a region. Number of species per unit area is called species richness. Eveness or equitability differs due to difference in number of individuals in an area. With increase in area, number of species increase.
Usually, species diversity increases, if species richness is higher. Somehow, number of individuals among species may differ.
This may lead to differences in evenness or equatibility. This also results to change in diversity.

They describe communities located across different regions across the world, looking at the interactions between climatic factors, living organisms, and substrates found in the environment. As you have learned in the readings, extinction is a natural selection process. You have also read that humans are often responsible for accelerating this process.
