BIOMES LAB BIOL 120 `` A biome is a major complex of similar communities. It is the largest ecological unit we recognize. Different books vary in the number of biomes they list. Temperature and precipitation are the two key factors that determine the different type biomes. Some books consider marine ecosystems and freshwater systems as biomes. Others break out wetlands as a biome. We will look at 10 terrestrial biomes: 1. Tundra (Arctic and alpine) 2. Boreal forest or taiga

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

How and why do the world’s biomes differ in their biomass production? The definition of biomass is the total quantity or weight of organisms in a given area or volume. Biomass can differ because of many things‚ including temperature‚ rainfall‚ location‚ and altitude. Tundra and Tropical Rainforest are two contrasting biomes‚ different in many ways. First of all‚ location. Tundra is located in the coldest parts of the world‚ like the most northern parts of America (i.e. Alaska)

2013 Chapter 11 Key Terms Q1: Contrast and explain the concepts of ecosystem and biome. A: An ecosystem is a natural unit consisting of all plants‚ animals and micro-organisms in an area functioning together with all the non-living physical factors of the environment. Among terrestrial ecosystems‚ the type that provides the most appropriate scale for understanding world distribution pattern is called a biome. Q2: What is an ecotone? A: A region of transition between two biological communities

that we were given our local climatogram most resembled the mid latitude (temperate) grassland biome of Lawrence‚ Kansas . I arrived at this conclusion by comparing the two climatogram graphs and noticing a striking resemblance. The precipitation and temperature were almost exactly the same. Although they have similar qualities‚ the two climatograms also have many distinct differences. In our local biome we can observe that there is more rain in the summer months. We also that the temperature in the

Succession often leads to a faily stable collection of organisms called a climax community. Land Biomes A biome is an environment that has a charcteristic climax community. The Earth is made up of two main biomes: land biomes and aquatic biomes. The major biomes are the tundra‚ taiga‚ temperate decidous forest‚ grassland‚ tropical rainforest‚ and desert. Tundra Tundras are the northermost biomes. They have nearly no tress and are covered

Vegetation (living and decomposing) ii). Mammals‚ insects‚ birds and microorganisms Biomass-the mass of material in the bodies

in temperate broadleaf and mixed forests‚ a more even distribution exists between evergreen and deciduous trees.Temperate deciduous forests‚ a subgroup of temperate broadleaf forests‚ consist of trees that lose their leaves every year. Finally‚ temperate rainforests typically have heavy rainfall and dense humidity. In the temperate region‚ winters are mild and rainfall is moderate.The forests have trees‚ scrubs and bushes.There is less undergrowth. Most of the trees are deciduous‚ which shed their leaves during

Ecosystem Lab Presentation – Savannas The biome I will be presenting on is a savanna‚ also spelled savannah. Savannas are a type of grassland ecosystem. Savannas house rolling grassland scattered with shrubs and isolated trees. Savannas can be found between a tropical rainforest and desert biome. Inhabitants of the savanna are very diverse and abundant. Some of the wildlife that makes the savanna their home are lions‚ giraffes‚ elephants‚ and zebras just to name a few. There are also various
