Animals accumulate wastes like urea, uric acid, \(\mathrm{CO}_{2}, \mathrm{H}_{2} \mathrm{O}\), ions like \(\mathrm{Na}^{+}, \mathrm{K}^{+}, \mathrm{Cl}^{-}\), phosphate, sulphate, etc, by
1 Metabolic activities
2 Excess ingestion
3 Excretion
4 1 and 2
Explanation:
Animals accumulate ammonia, urea, uric acid, carbon dioxide, water and ions like \(\mathrm{Na}^{+}\), \(\mathrm{K}^{+}, \mathrm{Cl}^{-}\), phosphate, sulphate, etc., either by metabolic activities or by other means like excess ingestion. These substances have to be removed by the process of excretion.
