Reduces water loss compared to other nitrogenous wastes but requires more metabolic energy to produce
Mammals excretes urea as the primary nitrogenous waste product. On the other hand birds, and reptiles excretes uric acid as the primary nitrogenous product. They are called uricothelics because they can convert ammonia to uric acid. Uric acid is a compound similar to purines. This is produced through a complex metabolic pathway thay cost high energy. However it has advantages such as reducing water loss.
The abiotic factors in salt marshes include:
1. High, variable salinity
2. Low oxygen levels
3. Turbidity
4. Varying temperature
5. Sulphide toxicity
Salt marshes occur in zones between low and high tides. Salt marshes are periodically flooded by tides , so the plants living there have had to adapt to being submerged in salt water.
Only a limited number of plant and animal species can tolerate the harsh conditions of salt marshes and therefore salt marshes are generally poor in species.
