Question
Chapter 11, Problem 1TYC
To determine
The biodiversity and the three levels of biodiversity.
Expert Solution & Answer
Answer to Problem 1TYC
Biodiversity involves the wide variety of different species that live together on earth and forms ecosystem. There levels of biodiversity include genetic diversity, species diversity and ecosystem diversity.
Explanation of Solution
Biodiversity is defined as the variability among living organisms which comes from all sources that include terrestrial, marine and other aquatic ecosystem and all the species on earth together form an ecological system where they live, reproduce and evolve new species. It involves diversity within members of species, between species and of ecosystem. Biodiversity is the formation of ecosystem services and it also involves human beings. The three level of biodiversity are genetic diversity, species diversity and ecosystem diversity.
(a) Genetic diversity: It is defined as the genetic information carries genes of all the species. It also involves the variation of genetic information between species as well as variations between the individuals of species.
(b) Species diversity: It involves the different variety of species on earth. It also involves the number of species and number of individuals within each species.
(c) Ecosystem diversity: It involves the various habitats, natural communities and ecological processes in biosphere where different groups of species survive and reproduce.

The surplus of heat at the equator and the deficit at the Poles drives our atmospheric instability. Instability is a good thing! Without the unstable conditions, there would not be any atmospheric motion. The overheating of the equator pumps atmospheric uplift. As the air rises into lower pressures, it expands and cools... adiabatic cooling! The air migrates north and south and becomes denser than the surrounding air and sinks. The sinking air enters higher pressures and creates the subtropical high pressures and adiabatic heating...whaaaa-la! We have Hadley Cells! Not to mention, the Rainforests and World's largest deserts too! We now can imagine the Hadley cells in three-dimensions. They more or less "sandwich" the equator during the spring and fall equinoxes. However, what happens in the summer and winter? mP Maritime polar…arrow_forwardUsing the map.
