Marine Ecology - Water Properties

Which of the following is NOT a similarity between aquatic and teresstrial ecosystems

• In bothe terrestrial and aquatic environments the ecosystems include communities made up of a variety of species

• Within Both Communities there are populations at each trophic levels

• In both ecosystems organisms are NOT interdependent on each other

• In undisturbed terresstrial and aquatic ecosystems equilibrium is reached i.e very few changes are observed over a period of time.

Which of the following is NOT a difference between aquatic and terrestrial ecosystems.

• Aquatic ecosystems are so rich in nutrients that they support more life than an equivalent terrestrial ecosystem.

• Aquatic ecosystems are less stable than terrestrial ecosystems with less fluctuations in temperature and other variables.

• Aquatic ecosystems are morestable than terrestrial ecosystems with less fluctuations in temperature and other variables.

• Oxygen is sometiimes a limiting factor in aquatic ecosystems but this is seldom the case in terrestrial ecosystems

The molecular structure of water allows for all of the following EXCEPT.

• A single water molecule has One hydrogen and Two oxygen

• Water molecul has a covalent bond between the Hydrogen and the Oxygen

• Water molecule has a polar force of attraction

• Water molecule has a high latent heat of vaporization due to the angles in the molecular structure
