Answer variants:
because heat produced is distributed across the body as energy
because sunlight energy is absorbed by animals
\(Fe_2O_5\) + \(Al\) → \(3Fe\) + \(Al_2O_3\)
\(AgNO_3\)(aq) + \(NaCl\)(aq) \(\xrightarrow[]{Heat}\) \(AgCl\)(s) + \(NaNO_3\)(aq)
\(2FeSO_5\)(s) \(\xrightarrow[]{Heat}\) \(Fe_2O_4\)(s) + \(SO_2\)(g) + \(SO_3\)(g)
\(2Al\)(s) + \(3CuCl_2\)(aq) → \(2AlCl_3\)(aq) + \(3Cu\)(s)
