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.

Answer:
The relationships include symbiosis, predation and competition.
Explanation:
Organisms relate with each other in different ways in the environment. Such relationships include:
Competition: This deals with the struggle between organisms for food and other available resources. The strongest and fittest usually have a higher chance of survival.
Predation: This is the process by which bigger animals prey on smaller animals for food. This helps in movement of energy in the trophic levels and also the balancing of the eco system.
Symbiosis: This is a mutual relationship in which two organisms form a type of partnership and benefit positively from each other.
