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
Answer:
Coral reef bleaching
Explanation:
<em>The correct answer would be coral bleaching.</em>
Coral bleaching is generally define as the change in color that results from the expulsion of green symbiotic algae from the tissues of the coral.
The expulsion of symbiotic algae from the tissue of coral is usually caused by a change in stressor factors of ocean water such as light, temperature, nutrient.
<u>When the temperature of ocean water increases as a result of global warming, the vibrant color of corals may be lost because the change in stress condition usually leads to the degradation of the algal pigments or outright expulsion of the symbiotic algae from the tissue of the corals. When this happens, it leaves the coral tissues completely white and they are said to have been bleached.</u>
Answer:
C. Mudflow
Explanation:
The land contains approximately 60% of water in a mudflow.
:D
Answer:
Selenium mineral.
Explanation:
Vitamin E deficiency causing by the selenium mineral, not having enough selenium which is needed in our body system, this deficiency can cause many health problems. It is known as a trace mineral which is important for human health.
It may cause premature infants and develop a serious type of anemia, weak muscles and difficulties in walking, impaired coordination, & reflexes. The diagnosis of this deficiency is depends on physical examination, and symptoms.
