Key Points

• A grassland ecosystem is a dry area of land dominated by grasses.
• Huge trees and shrubs are very rarely found in these regions, which is mainly because of the climatic conditions and other environmental factors, which do not withstand the plant’s requirements.
• These ecosystems are mainly found in regions, where there is a scarcity of water and not enough and regular rainfall to support the growth of plants and forests.
• The grassland ecosystem lies between the deserts and the forest ecosystems.
• Grasslands are one of the major types of terrestrial biomes in the world. They are home to a wide diversity of animal species and are found throughout the world, except for a few regions.
• Grasslands are subdivided into two types:
  • Tropical Grasslands:
    • These regions are warm throughout the year, followed by dry and wet seasons.
    • They receive an average annual rainfall ranging between 30 and 35 inches.
    • These tropical grasslands are characterized by tall grasses or relatively short grasses.
    • Savannah, Great Plains of the Midwest, Palouse Prairieare the best examples of tropical grasslands.
  • Temperate Grasslands:
    • These grasslands are similar to tropical grasslands, except for the climatic conditions.
    • They have cold winters and warm summers with 30 and 35 inches of annual rainfall.
    • Shrublands are the best example of temperate grasslands.
    • Steppe in Eurasia, Prairies of North America are examples of temperate grasslands.

• Digestate is the substance left over after a biodegradable feedstock has gone through anaerobic digestion (decomposition under low oxygen conditions).
• It is used as anAgriculture Fertilizer.
• Digestate and biogas are the two major products of anaerobic digestion.
• Acidogenesis and methanogenesis both create digestate, which has different properties.
• Ethane has the chemical formula C₂H₆ and is an organic chemical molecule.
• Bioethanol is an alcohol created mostly from carbohydrates produced in sugar- or starch-bearing plants such as corn, sugarcane, sweet sorghum, or lignocellulosic biomass by microbial fermentation.
• Biogas from waste digestion plants is used to make bio-methanol.

Important Points

• Fertilizers are chemical substances that are applied to crops in order to boost their yield.
• Farmers utilise these on a daily basis to boost crop productivity.
• The fertilisers include nitrogen, potassium, and phosphorus, which are all vital minerals for plants.

Biomes Question 12 Detailed Solution

Key PointsTropical Rainforests:

• Tropical Rainforests are mainly located between the latitudes of 23.5°N (the Tropic of Cancer) and 23.5°S (the Tropic of Capricorn)—the tropics.
• Tropical rainforests are found in Central and South America, western and central Africa, western India, Southeast Asia, the island of New Guinea, and Australia.
• Tropical rainforests are well known for their lush vegetation and high biodiversity. However, the nutrients in these ecosystems are largely contained within the living organisms themselves rather than the soil.
• The nutrient cycle in tropical rainforests is very rapid. When an organism dies, the high temperature and moisture cause the dead organic matter to decompose quickly, releasing nutrients back into the ecosystem where they are rapidly taken up by plants and other organisms.
• Thus, the soil itself is typically poor in nutrients because they do not stay in the soil long enough to accumulate. Hence statement (I)is incorrect
• The high temperature and humidity of tropical rainforests promote rapid decomposition of dead organic matter.
• The heat and moisture speed up the activities of decomposers like bacteria and fungi.Hence statement (II)is correct
• These organisms break down dead plant and animal material, quickly recycling their nutrients back into the ecosystem.
• However, as explained before, these nutrients are swiftly taken up by living organisms, preventing their accumulation in the soil.
