Earth Science Ecology Group 11 Objectives: * To define Ecology * To differentiate abiotic and biotic components of the ecosystem. * To identify the different types of ecosystem. * To know the different elemental cycles * To understand the importance of the natural habitat and the effects of migration. * To know have an overview of what is food chain and food web * To differentiate renewable from non-renewable resources * To know what is population‚ migration

seasonal streams and consists of varied landuse/landcover (LULC) classes like the crop fields‚ fallow land‚ urban‚ grassland‚ shrubs‚ and vegetation of mix type. The western part is covered with various vegetation features of Sal‚ Teak‚ and Bamboo. The southern part is covered with the urban built up area and some patches of vegetation. The urban area of the city is scattered and irregular. A seasonal river named Tons flows from North East to South West direction. 5. Data Used HYPERION is an EO-1

FIGURE 3: Cape Flats Sand Fynbos in Lower Tokai Park. Fynbos is a fire-driven ecosystem‚ requiring regular burning to rejuvenate and survive. Fynbos should ideally be burnt every 15 years‚ and preferably later in summer. This burns the moribund vegetation‚ returns the nutrients to the soil and triggers the germination of seeds. Some plants achieve this when the fire triggers dead flower heads to release dormant seeds‚ while other seeds remain dormant in the ground until they are 3 triggered by the

More than 200 species of birds and mammals‚ numerous reptiles and amphibians‚ and thousands of types of insects and other invertebrates live in the park. Diversity is the most important feature of the vegetation found within Chino Hills State Park. Also the park has several different kinds of vegetation in each of its major habitats. In the park’s creek zones‚ cattail stands provide habitat for a variety of wildlife‚ among them red-winged blackbirds. Over the centuries many people have made use of the

and beautiful landforms that are valuable and unique. These landforms provide many benefits that have important outcomes for the economy‚ and the survival of life and vegetation in Australia. Australia’s most precious landforms are its water bodies each of which has a very important role for the survival of life and vegetation in Australia. The two largest and most important water bodies in Australia are its large natural inland lakes and man made dams; both these landforms provide the essential

plant distribution For example the Palmae/Arecaceae are cold intolerant as their single meristem is susceptible to frost. Conversely‚ boundaries between vegetation types (e.g. Arctic treeline) are generally determined by summer warmth * Rainfall is also an important determinant: for example it affects the balance of grasses to woody vegetation * Other factors such as soil type or herbivory may also be affected by climate change. Effects on Plant Diversity * Species ‘left behind’ as they

temperatures never go above 45o or 50o F. In winter‚ temperatures don’t reach above 20o F and average between -20o to -30o F. Tundra biomes receive low levels of precipitation‚ around 150 to 250 mm of rain per year. Due to the harsh climate‚ vegetation such as low shrubs‚ sedges and reindeer mosses have adapted by growing close to the ground and close together‚ as this helps plants to resist the effects of cold weather and reduce damage caused by snow and ice. Plants are also small and roots are

It almost feels as if the area on that side of the track is dead with no vegetation surrounding it. The other side of the track has lots of vegetation; there are trees‚ fields of grain‚ and a river. In between the trees‚ the girl can make out hills that she refers to as “white elephants.” Her reference to white elephants can be related to the representation of

permafrost‚ which means it has a thick layer of frozen soil throughout the year. The latitude of the tundra is 66.5625 degrees north‚ 0 degrees east. The tundra does not have many types of vegetation. It has shrubs‚ grass in some parts and a lot of mosses. The tundra is too cold to be able to grow a lot of vegetation. The animals that live in the tundra are the arctic foxes‚ musk ox‚ the snowy owl‚ lemmings‚ and the polar bear! One of the animals that live in the tundra‚ the snowy owl‚ is very interesting

Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity‚ the environment‚ and its effect on food security and the quality of life. Productivity impacts of land degradation are due to a decline in land quality on site where degradation occurs (e.g. erosion) and off site where sediments are deposited. However‚ the on-site impacts of land degradation on productivity are easily masked due to use of additional inputs and adoption
