Caco3+ CO2+ H2O-2(HCO3l+ Ca2 CO2 Ca 2 H20 CaCO3

Explanation / Answer

answers.

41) mussels are eaten by starfish so the relationship between them is predator/prey.

42) Longshore transport is caused by longshore currents and beach drifts.Oceanic water moves with tidal forces and it gets breaked at different places. The transport of sand and sediments along the shore is longshore transport.So for this to happen oceanic currents .tidal forces are required.

43) In the given chemical equation ,CaCO3 + CO2 + H2O = 2(HCO3)-1 + Ca+2. (HCO3)-1 and Ca+2 are the ions generated.Right side portion is the ion portion.

44)FALSE, plankton movement not possible.

45)TRUE,
