"TEMPERATE GRASSLAND" Temperate grasslands are defined as places where grasses predominate over trees and shrubs. The name for this biome‚ temperate grasslands‚ is a great description for what it is like there. The most important plants in this biome are grasses. Two major kinds of grasslands in the world: • Savannas • Temperate grasslands. Savannas are defined as places where individual shrubs and trees are scattered among the grasses. Temperate grasslands: trees and shrubs are

TUNDRA The Tundra is the coldest of all the Biomes and being situated in the extreme north of the planet has desert like conditions. It has extremely low temperatures‚ poor nutrients‚ and short growing seasons. There is a very low precipitation of less than five inches a year which is coupled with strong‚ dry winds. There is a very large annual amount of snowfall in the region which surprisingly is advantageous to plant and animal life as the snow provides and insulation layer on the surface of

Chapter 1 Environmental Problems‚ Their Causes‚ and Sustainability Summary 1. All life depends on energy from the sun‚ solar capital‚ and the resources and ecological services of the earth‚ natural capital‚ to survive. An environmentally sustainable society provides for the current needs of its people without undermining the ability of future generations to do the same. 2. The world’s population is growing about 1.2% per year‚ which adds about 77 million people per year. Economic growth

Land based ecosystems = terrestrial ecosystems or biomes. (Forests‚ deserts‚ grasslands). Differences between terrestrial ecosystems primarily arise from variations in average temperature and precipitation. Water based ecosystems = aquatic ecosystems.

Armadillidiidae is a family of woodlice‚ a terrestrial crustacean group in the order Isopoda. Unlike members of other woodlouse families‚ members of this family can roll into a ball‚ ability they share with the outwardly similar but unrelated pill millipedes and other animals. It is this ability which gives woodlice in this family their common name of pill bugs‚[1] doodle bugs‚ or roly polies. The best-known species in the family is Armadillidium vulgare‚ the common pill bug. The Classification
