1) (a)How does a snail adapt to its surroundings?
They are able to adapt to a variety of living conditions and they do not require much food. They have been able to able to continually evolve to survive the conditions around them. It has hard shells to protect from predators, long antennae for enhanced sense's of smell and touch and has lubricated(slimy) surface for extra mobility. During certain circumstance, the snail can fully retract into it's shell for protection.
(b) What preys on snail and what does a snail eat?
It preys on dead plants, rotting plants and animals, plants and algae. Shrews, leeches and ducks feed on it.

2) How are plants able to stay on sand?
The sand on the coast are a buffer zone between the land
and the sea and serve to protect the delicate land plants from the salt air and
wind coming from the ocean. Burial levels vary in different coastal sand dune systems and influence the physical and biotic microenvironment of the plant and soil.

What I have learnt
I have learnt that pH is a measure of the acidity or basicity of a solution and also the abiotic factors of living things. The physical factors are humidity, temperature and pH. Seawater has an average amount of pH so living things are able to survive in it. A too high or low amount of pH results organisms unable to live in it.
