AQA GCSE Chemistry What is a mixture? - ANS Two or more elements not chemically bonded What is the difference between a compound and a mixture? - ANS Compounds have a fixed composition whereas mixtures do not. Mixtures are not chemically bonded but compounds are. Describe the process of filtration - ANS Pour the mixture onto the filter paper, the liquid simply passes through the filter paper into the flask. The insoluble solid cannot pass through and so it stays on the paper...

Efficiency of biomass transfer - answer-Biomass of previous trophic level divided by biomass of current trophic level then x 100 Saprobiotic nutrition - answer-Fungi and bacteria that produces enzymes within the cell which are then transported outside of the cell (extracellular) to digest biochemicals. They then absorb the products. Nitrogen fixation - answer-Taking nitrogen gas and incorporating it into a nitrogen compound. Rhizobium - answer-Found in root nodules. Fix nitrogen into am...
