(a) Primary consumers: These feed directly from the grasses (grazing) and include herbivores such as Cows, Buffaloes, Goats, Rabbits, Mouse etc. I. Biotic components . occur in regions too dry for forests and too moist for deserts, v   The grassland, consumers are of three main types; The ecosystems. What is the economic importance of Algae? Typical grasslands are vegetation formations that are generally found in temperate climates. Wild nutrients are released for reuse by producers. The The functioning of forest ecosystems is characterised by energy and nutrient flows and cycling, biomass production and the decomposition of dead organic matter. All of nature benefits when the soil is covered by, protected by, cleansed by , strengthened by and improved by a cover of grass. Actinomycetes. v In grassland, producers are mainly grasses; though, a few herbs & shrubs also contribute to primary production of biomass. Grassland Ecosystem: Grasslands occupy about 19% of the earth’s surface. In an ecosystem, the food chain does not follow the linear pattern, but an organism may feed upon more than one organism in the same food chain or upon organisms of different food chains. Shall we explore some of the most common terrestrial ecosystems you can come across? (also called Greenswards) are areas where the vegetation is dominated by and also insects, termites, centipede, millipedes etc. v In a forest, the producers are mainly trees. Tundra ecosystems are devoid of trees and are found in cold climate or where rainfall is scarce. which feed on the primary consumers. There are six main types of grasslands—tropical grasslands, temperate grasslands, flooded grassland ecosystem, tundra grasslands, montane grassland and Xeric grassland ecosystem. The producers (green plant) takes up the mineral elements from the soil and air, convert them into organic form and after passing through the different trophic levels, are again returned to the soil and air. annual rainfall ranges between  25- 75 The ecosystem in the Arctic or … Megaherbivores and small burrowing mammals commonly coexist and play important functional roles in grassland ecosystems worldwide.

Grassland ecosystems are present in every single continent on this planet with the sole exception of Antarctica, which is too cold to sustain a grassland ecosystem. contribute to primary production of biomass. The Grassland Ecosystem is an area where the vegetation is dominated by grasses and other herbaceous (non-woody) plants. The grasslands we see today have an extensive history of human activity and disturbance. Grasslands cover 41% of Earth's land surface and provide livelihoods for nearly 800 million people, as well as forage for livestock, wildlife habitat, valuable ecosystem services, and locations for recreation and tourism (Zhang 2006, Strömberg et al. Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modeling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing, 100101 China. The rest of India’s grasslands are mainly composed of the Steppes and Savana. Within the grassland ecosystem are enormous numbers of very small organisms, including bacteria, fungi, algae, and viruses. which provides food, milk, wool and transportation to man.

In aerial environment. place. Complementary Chinese topic: Resilience of grassland ecosystem services to abiotic stress depending on biodiversity: (b) nitrogen cycling . The interactive effects of these two functional groups of herbivores in shaping the structure and function of grassland ecosystems are poorly understood. The producers fix the solar energy and produce the complex organic matter with the help of minerals. From a systems perspective, the hundreds of species of bacteria and fungi are particularly important because they decompose organic material, releasing carbon dioxide and other gases into the atmosphere and making nutrients available for recycling. Grasslands (also called Greenswards) are areas where the vegetation is dominated by grasses and other herbaceous (non-woody) plants. The Suklaphanta wildlife reserve is one of the examples of grassland in Nepal which is located at far- western part of Nepal. 2) Consumers I. Biotic components .
