THE HABER PROCESS • used to convert nitrogen into ammonia which is used in fertilisers. Nitrifying bacteria convert the ammonia into nitrates • Plants can only absorb nitrogen in the form of nitrate So they depend on nitrogen- fixing bacteria to convert nitrogen in the air into nitrove in the soil. Nitrogen in the air is converted into nitrates in the soil by nitrogen - fixing bacteria. Plants absorb nitrates and use the mineral to make proteins. Decomposition of animal waste or dead matter converts nitrogen in amino acids into ammonium ions (which are turned into nitrates by nitritying bacteria). Denitrifying bacteria decreases the amount of nitrates in the soil by converting them into atmospheric nitrogen. THE CARBON CYCLE •Carbon dioxide is removed from the atmosphere and converted into organic carbon, by photosynthesis. • the carbon-containing compounds go through the food chain when one organism eats another.. • respiration in plants and animals returns carbon dioxide to the atmosphere • (as well as combustion of feuls) •Decomposition of organic matter releases carbon dioxide because the microorganisms which decompose the organism are respiring. ENERGY FLOW THROUGH ECOSYSTEMS • Energy is lost at each level • only AND DURING und 10% of energy is passed on at each trophic...

level So food chains generally can't have more than 5 trophic levels RESPIRATION DOES RELEASE ENERGY BUT THIS CANNOT BE PASSED ONTO THE NEXT LEVEL BECAUSE IT IS USED FOR MUSCLE CONTRACTION, GROWTH AND HEAT ECOSYSTEMS always stare FOOD CHAIN PRODUCER with a producer make their own food PRIMARY CONSUMER organism that eats producers PYRAMIDS OF NUMBERS GRASSHOPPER GRASS BUETIT CATERPILLAR FREE SECONDARY CONSUMER 1 TERTIARY CONSUMER shows the direction of flow of energy. ECOLOGICAL PYRAMIDS represent food chains as pyramids of numbers or pyramids of Energy. each level of the pyramid represents a trophic level the size of the bar represents the numbers/mass) energy at that level.. organism that eats primary consumers not always pyramid ・Shaped - →FOOD WEBS WORK IN THE SAME WAY BUT INVOLVE MORE ORGANISMS organism that eats secondary consumers (sometimes called the Top carnivore) ·PYRAMIDS OF BIOMASS LIZARD DRAGONFLY GRASSES Biomass is the dry mass of a plant or animal species • always gives a pyramid shape PYRAMIDS OF ENERGY ARE ALWAYS TRIANGLE SHAPED.
