Alleles determine the trait that a given gene will express. There has to be at least one dominant allele for the genes to express a trait though.
Answer:
The stress which occurs in the ecosystem are high temperature and salt concentration in the soil. So if the ecosystem has maximum biodiversity, there will be less affect on the ecosystem because the organisms which lives in that ecosystem show resistance against these stresses.
With the increase of biodiversity of the ecosystem, also increased the resistance against the stress and if the biodiversity decreases in the ecosystem, the ecosystem is greatly affected by the stress.

Coastal zones
Explanation:
Soft bottom intertidal habitats include seabed made up of fine grains of sediments, sand and mud. Depending upon the grain size of the sediment, depth of the seabed, temperature and light exposure, growth of bacteria or microalgae, the biodiversity of these habitats varies. A vast population of burrowing marine organisms like clams, crabs, snails, shrimps, skates, fluke, rays, sea cucumber etc are all found in this habitat. Commercial fishing is a main hazard in this habitat.
An estuary represents an area composed of water and wetland, where a freshwater body (like rivers, stream) meets an ocean. The unique feature of this habitat is the presence of salty brackish water which is a mixture of the salty ocean water and the fresh water.
Salt marsh is a coastal wetland that is mostly flooded and drained by the tidal salt water. The wetland is composed of mud and peat and hence is marshy. Tides often submerge the marshes and hence contain decomposed organic matter.
Mangroves are wetlands found along tropical areas with brackish waters. These help to prevent the ocean coastline. Halophytic plants and trees occupy these areas and form the typical mangrove forests in this habitat. Mangrove trees are unique with its prop root
