Ecosystems: Change and Challenge The Structure of Ecosystems Ecosystem: a dynamic‚ stable system characterised by the interaction of plants and animals with each other and with the non-living components of the environment The components of an ecosystem are categorised as either biotic and abiotic Biotic means the living environment‚ components include: i). Vegetation (living and decomposing) ii). Mammals‚ insects‚ birds and microorganisms Biomass-the mass of material in the bodies

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

Climate is a measure of the average pattern of variation in temperature‚ humidity‚ atmospheric pressure‚ wind‚ precipitation‚ atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate is different from weather‚ in that weather only describes the short-term conditions of these variables in a given region. A region’s climate is generated by the climate system‚ which has five components: atmosphere‚ hydrosphere‚ cryosphere‚ land surface‚ and biosphere

Trees are rare in the savanna biome because of A) insufficient annual precipitation. B) acidic soils. C) extreme winter temperatures. D) large variations in seasonal rainfall. E) permafrost. 2) Which of the following statements best describes the effect of climate on biome distribution? A) Average annual temperature and precipitation are sufficient to predict which biome will be found in an area. B) Seasonal fluctuation of temperature is not a limiting factor in biome distribution if areas have the

Things like water‚ soil‚ sunlight‚ and climate all come together to form the biome. One of the most important abiotic factors of this biome is water. It’s common knowledge that the average rainfall in the Madagascar Rainforest is fairly high‚ so much so that only certain plant and animal wildlife are fit to live there. If the rainfall were to decrease for any reason whatsoever‚ it’s highly likely that the amount of organisms alive would also decrease. Another

exists. For example‚ an introduction to geography gives the knowledge of understanding how certain landforms were formed‚ or why certain bodies of water exist. This further leads to how certain weather patterns form‚ thus creating different types of biomes and substantial agricultural productions. Geographers ask the basic questions that answer much more complex questions. This leads to the “My Country Profile Assignment‚” for which I have been assigned the country of Afghanistan.

➢ Competing – Two species compete with another species for resources such as food‚ water‚ or territory ➢ Biomes – major types of ecosystems that occupy very broad geographic regions. ➢ Photic zone is where there is enough light for photosynthesis to occur and an aphotic zone‚ where very little light penetrates. ➢ Benthic zone - is located at the bottom of the biome ➢ Oligotrophic lakes are deep lakes that are nutrient-poor and oxygen-rich and contain sparse phytoplankton.

Taiga Fun Facts By James Stuart‚ eHow Contributor The taiga is an ecosystem‚ or biome‚ that makes up a significant part of Canada and the northern regions of Asia and Europe. The taiga is the world’s largest biome and primarily comprises coniferous trees‚ which are made up of needles and stay green year round. The taiga biome is also known as the boreal forest. Temperature The taiga has a very cold climate with winter temperatures as low as minus-54 degrees Celsius. Summer temperatures

undulating and rough terrains are areas where grassland and woodlands develop and give shelter to a variety of wild life. Soil The soils also vary over space. Different types of soils provide basis for different types of vegetation. The sandy soils of the desert support cactus and thorny bushes while wet‚ marshy‚ deltaic soils support mangroves and deltaic vegetation. The hill slopes with some depth of soil have conical trees. CLIMATE Temperature The character and extent of vegetation are mainly determined

Hence climate is the main soil forming factor that could possibly make any distinguishable characteristic change to soil properties between the regions. Climate‚ as both temperature and rainfall‚ has major effects on organic matter‚ chemical composition‚ base saturation and contents of carbonates and soluble salts (Young‚ 1976). The tropics of Australia consistently experience warmer annual temperatures. Warm temperatures coupled with high
