Objective: 
 Students will be able to enhance their knowledge about significance of biogeography and ecosystem including principles of ecology, conservation of biodiversity and geo-biochemical cycles. They will be able to know how distribution Patterns of plants are the result of climatic and geographical conditions and how their evolution of Texan (genus or species) has taken place on the earth surface in different bio geographic regions.Students will be able to distinguish between the factors different kind of factors affecting plants, environment and biomes and learn about how animals evolve and adapt in different environment.They will be able to know how distribution Patterns of animals are the result of climatic and geographical conditions and how their evolution  has taken place on the earth surface in different geographic regions and dispersal of zoo-geographic regions of the world.
