25
Q

What are the three layers of the tropical rainforest?

A

Emergent Layer, Canopy Layer and Undergrowth Layer

26
Q

How tall are trees the emergent layer?

A

30 or more metres

27
Q

How tall are trees in the canopy layer?

A

20-30 metres

28
Q

Why is light blocked in the canopy layer?

A

Crowns of the canopy trees interlock and form a thick mass of branches and leaves that prevents light from passing through.

29
Q

What is the impact of less sunlight in the undergrowth layer?

A

Vegetation is relatively sparse. Not many plants are able to grow in the undergrowth layer

30
Q

What are mangrove trees?

A

Plants that can grow in water with higher salinity than freshwater.

31
Q

Where are mangroves typically found?

A

Along the coasts, normally in a tropical climate.

32
Q

Why are calm water conditions good for mangroves?

A

They encourage the accumulation of fine sediments containing nutrients which is good for their growth.

33
Q

What species of mangrove plants are found in the lower-tide level? Explain why.

A

Sonneratia and Avicennia. They are able to tolerate high salinity levels and longer periods of flooding.

34
Q

What species of mangrove plants are found in the higher-tide level? Explain why.

A

Rhizophora and Bruguiera. They are less tolerant of the high salinity levels in the lower-tide levels.

35
Q

What happens when there is too much precipitation?

A

Floods

36
Q

What happens when there is too little precipitation?

A

Droughts

37
Q

What are droughts?

A

a long period of little to no rainfall in a specific areaW

38
Q

What are the two main types of floods?

A

Flash Floods and River Floods

39
Q

What is a flood?

A

an overflow of a large amount of water onto dry land.

40
Q

Difference between flash floods and river floods.

A

Flash floods occur over a short period of time after exceptionally heavy rainfall.
River floods occur due to sustained heavy rainfall throughout a long period of time.

41
Q

Where do flash floods normally occur?

A

It occurs in dry areas where there is a lack of soil or vegetation

42
Q

What happens during a flash flood?

A

Water from heavy rainfall is not infiltrated and becomes surface runoff, flooding low-lying areas.

43
Q

What happens during a river flood?

A

Large amounts of rainwater and meltwater produced when snow and ice melt flows into rivers rapidly, overflowing the riverbank and flooding surrounding areas.W

44
Q

Where do river floods occur?

A

At the river, obviously.

45
Q

Is Saba noob?

A

yes

46
Q

What is a river ecosystem?

A

It refers to the communities of plants and animals in rivers that interact with one another

47
Q

What is a food chain?

A

It shows how energy is transferred through food. Predators gain energy they need by eating their prey.

48
Q

What are the four uses of water by humans?

A

Domestic, Recreation, Agriculture, Industry

49
Q

Examples of domestic uses of water?

A

Household activities such as bathing and cooking.

50
Q

Examples of recreational uses of water?

A

Leisure activities such as sailing and kayaking.

51
Q

Examples of agricultural uses of water?

A

Grow crops and rear animals for human consumption.

52
Q

Examples of industrial uses of water?

A

Used to generate electricity when passing through turbines.
Use as a cleaning agent in water fabrication.
Used to cool equipment when they get too hot.

53
Q

What are the four water management strategies in Singapore?

A

1) Improving Water Quality
2) Reducing Water Consumption
3) Improving Water Technologies
4) Importing Water

54
Q

How to determine water quality?

A

Water quality is determined by factors such as temperature, amount of dissolved oxygen etc.

55
Q

What is the relationship between water consumption and population of a country?

A

The higher the population of a country, the higher the demand for water, hence the higher the water consumption by both industries and people

56
Q

Why is it important to reduce water consumption?

A

Even though water is a renewable resource, it can run out faster than be replenished.

57
Q

What are examples of Singapore IMPROVING WATER QUALITY?

A

Public Utilities Board by NEA: If any company wants to release water into water bodies, they must get NEA approval.

58
Q

What are examples of Singapore REDUCING WATER CONSUMPTION?

A

Water Efficiency Labelling System: Helps people be more aware of water-efficient products > make more informed decisions when purchasing products.

59
Q

What are examples of Singapore IMPROVING WATER QUALITY?

A

NEWater allows Singapore to reclaim used water from water sources, making it drinkable again, and ensuring we are self-reliant.

60
Q

What are examples of Singapore IMPORTING WATER?

A

Singapore imports water from Johor, Malaysia: 1000 gallons per 3 sens.
