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
The term that refers to all areas of Earth where all life exists is call the Biosphere
The answer is ( In the early stages the embryos of four different species will look the same .For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth. That what makes them different.)
Answer: Heat ---from a warmer substance to a cooler substance
Explanation: Heat can be transferred from a hotter substance to a cooler substance. This can be done through three methods;
Conduction, Convention, Radiation
Conduction- When substance is been heated movement of particles increases causing collision between hotter particles and cooler particles. This continue until the temperature is in equilibrium. Metal is a good conductor of heat.
Convention- It is often associated with liquid and gases. hotter area of liquid moves and meet with cooler liquid. The cooler liquid then takes place of the hotter liquid until equilibrium is attain. This occurs while boiling water
Radiation - It doesn't need a means of transmission. It is gotten from infared emission. Infared emission increases when temperature increases .
