A forest ecosystem is a major ecologic unit. The forest ecosystem is associated with land mass covered in trees. The forest ecosystem includes biotic (living) interactions between plants, animals and micro-organisms, and abiotic (nonliving) physical and chemical interactions.
3) Identify a key abiotic component of a forest ecosystern
A) birds
B) water
trees
D) algae

1) a. water molecule breaks up into hydrogen and oxygen on passing electricity. does this involve breaking intermolecular or intramolecular forces of attraction. explain b. on boiling water changes to water vapor. does this involve breaking intermolecular or intramolecular forces of attraction. explain methanol evaporates faster than water. contrast the intermolecular forces and the vapor pressures of methanol and water?
