(ii) Official figures state that 100 g of groundnuts contain 2 428 000 J energy. With reference to the apparatus in Fig. 2.1, suggest two reasons why the
experimental energy value for 100 g of groundnuts is much lower than the official
energy value.

i believe the answer is snake.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
