The total nitrogen concentrations for freshwater should be no more than 1.3-2.2 milligrams per liter and the phosphorus levels should also be low. It is not good to have low levels of dissolved oxygen in water because only organisms such as leeches‚ snails and roundworms can survive while many other invertebrates would die. The pH scale is also used to test water quality. Water with a pH between 6.5-8.5 is considered to be healthy (Riverwatch‚ 2013).There are 3 types of pollution tolerance among invertebrates

EXERCISE 2: Effect of Human Activities on the Lake Ecosystem I.

A Fairy Song Over hill‚ over dale‚ Thorough bush‚ thorough brier‚ Over park‚ over pale‚ Thorough flood‚ thorough fire! I do wander everywhere‚ Swifter than the moon’s sphere; And I serve the Fairy Queen‚ To dew her orbs upon the green; The cowslips tall her pensioners be; In their gold coats spots you see; Those be rubies‚ fairy favours; In those freckles live their savours; I must go seek some dewdrops here‚ And hang a pearl in every cowslip’s ear.
