Q

Water is the universal..

A

solvent

17
Q

Certain properties of water allow it to transport biotic and..

A

abiotic components along each route it takes

18
Q

Water molecules are POLAR (different charges at each end), resulting in a weak attraction between molecules also know as..

A

hydrogen bond

19
Q

The weak attraction in water enables water to..

A

dissolve a wide variety of substances

20
Q

When water is used to dissolved substances to transport nutrients, the process of this is..

A

biogeochemical cycling

21
Q

The hydrogen bonding in water allows it to remain in a ..

A

liquid state, in different temperature range

22
Q

Because water can remain in a liquid state in different temperature range, water can continue to be transported and..

A

dissolve substances over and over again

23
Q

Energy is required if wanting water to change its state, the amount of energy needed to increase it’s temperature is..

A

a large amount of energy

24
Q

When water cools, hydrogen bonds loosen which cause cold or frozen water to have..

A

Lower density

25
Q

When water heats up, these bonds tighten which causes the warm water to have..

A

higher density

26
Q

Cohesion is the attraction for molecules of molecules of..

A

the same kind

27
Q

Like cohesion, water molecules are polar which means they are..

A

attracted to one another

28
Q

Cohesion causes surface tension which allows some insects..

A

able to walk on water

29
Q

In adhesion, water molecules are attracted to molecules of..

A

other substances. Such as the inner surface of a glass tube.

30
Q

Adhesion provides an upward force of on water the counteracts..

A

the pull of gravity

31
Q

adhesion and cohesion work together in plants to..

A

pull water up the tissue of plants which then leaves for transpiration

32
Q

Water plays an important ROLE in distributing..

A

minerals and nutrients throughout our planet

33
Q

Water is also required to support the cellular activities of most living things, the adult human body is composed of..

A

70% water. 95% water for plants

34
Q

When there’s not enough water in plants, plants respond by closing their..

A

stomata

35
Q

Plants close off any openings that releases water when water is scarce, this reduces..

A

transpiration (this is often used by desert plants such as cacti)

36
Q

Nutrients cycling in ecosystems:

Biogeochemical cycles are nutrients that travel through both..

A

biotic and abiotic parts of the environment.

37
Q

There are 2 types of biogeochemical cycles..

A

global and static cycle

38
Q

In biogeochemical cycles, the global cycle allows C, O, N and P to travel..

A

long distances as gases in the air

39
Q

in biogeochemical cycles, the static cycle refers to the P, K, Ca and other trace elements found in the soil do not..

A

travel as far
