How Do Organisms Deal With Salinity

There are two different approaches to estimation of mortality caused by entrainment, which are the demographic and conditional mortality approaches.The demographic methods convert the lost organisms to equivalent numbers of adults, which necessitates that the detailed life history of each organism must be known.

Polar bears survive very well in low temperatures, but would die from overheating. The salmon tolerates huge changes in the salinity (salt content) of the various. Another important aspect is that all organisms have tolerance ranges. Humans also can't go too deep into the ocean, because we can't handle the pressure.

Micro-organisms are present everywhere; in the air, in water, on plants and in the soil. They can remain dormant for long periods in many different ways, as spores, mitochondrion (a membrane-enclosed organelle found in the cells of most organisms) or hyphae, and they can live up to several years and on a wide range of hosts.

Materials. Brine shrimp—If you did the first lesson in the series (Brine Shrimp 1: Hatching Brine Shrimp), then students can use the brine shrimp that they hatched in the first lesson.If not, students will need to hatch brine shrimp (which takes a day or two) or you will need to provide the students with them.

Blue-green algae are actually a type of bacteria known as Cyanobacteria. Despite being called algae, they only have some things in common — they photosynthesise using light to produce oxygen and they need sunlight to grow.
