Q

What are the signs a plant has a magnesium deficiency?

A

leaves turn yellow

31
Q

What are the signs a plant has a phosphorous deficiency?

A
  1. poor root growth
  2. young leaves look purple
32
Q

What are the signs a plant has a potassium deficiency?

A

yellow leaves with dead patches

33
Q

What are the group of chemicals called that farmers add to soil to replace minerals?

A

fertilisers

34
Q

Why does a nitrate deficiency lead to poor growth?

A
  1. Nitrates are needed to make amino acids
  2. Which make proteins
  3. Proteins are needed for growth
35
Q

What three minerals are in NPK fertilisers?

A

Nitrogen (N)

Phosphorous (P)

and Potassium (K)

36
Q

What is the equation for aerobic respiration?

A

glucose + oxygen → carbon dioxide + water (+ energy)

37
Q

What are the reactants in aerobic respiration?

A

glucose and oxygen

38
Q

What are the products in aerobic respiration?

A

carbon dioxide and water

39
Q

Where in the cell does respiration take place?

A

Mitochondria

40
Q

What is the equation for anaerobic respiration?

A

Glucose → Lactic acid (+ energy)

41
Q

What is the purpose of respiration?

A

To release energy

42
Q

Which cells have lots of mitochondria for respiration?

A

Muscle cells

43
Q

How does the glucose for respiration get to your cells?

A

In the blood plasma

44
Q

How does the oxygen for respiration get to your cells?

A

Transported by red blood cells

45
Q

Name the red pigment in red blood cells that binds oxygen.

A

Haemoglobin

46
Q

How does the carbon dioxide produced in respiration get transported away from the cells?

A

In the blood plasma

47
Q

Which type of respiration releases most energy?

A

aerobic respiration

48
Q

Which type of respiration is used when there is not enough oxygen present?

A

anaerobic respiration

49
Q

What problem can lactic acid cause?

A

Muscle cramps

50
Q

What is oxygen debt?

A

The extra oxygen you need to inhale at the end of exercise to break down the lactic acid. Hence, you keep breathing heavily.

51
Q

What is the anaerobic respiration that produces ethanol and carbon dioxide called?

A

Fermentation

52
Q

What is the word equation for fermentation called?

A

glucose → ethanol + carbon dioxide (+ energy)

53
Q

Name the micro-organism used for fermentation in baking and brewing

A

yeast

54
Q

Why is fermentation useful in baking?

A

Carbon dioxide is produced as a gas.

Gas bubbles make the bread rise.

55
Q

What happens to the ethanol produced during the fermentation process in baking?

A

It has a low boiling point

So it evaporates

56
Q

What is the useful product of fermentation for the brewing process?

A

Ethanol

57
Q

What do the arrows in a food chain represent?

A

Energy being transferred

58
Q

Why are food chains often five organisms or less

A

Energy is wasted at each stage of the food chain, so there is not enough energy left to be transferred

59
Q

Give two ways that energy can be wasted in a food chain

A

e.g.

Inedible parts of an organism

Faeces

Movement

60
Q

What is more than one food chain linked together called?

A

Food web

61
Q

What is an animal eaten by other animals called?

A

Prey

62
Q

What is an animal that eats other animals called?

A

Predator

63
Q

Name the primary consumer in the following food chain:

oak tree → caterpillar → blue tit → sparrowhawk

A

caterpillar

64
Q

Name the secondary consumer in the following food chain:

oak tree → caterpillar → blue tit → sparrowhawk

A

blue tit

65
Q

Name the producer in the following food chain:

oak tree → caterpillar → blue tit → sparrowhawk

A

oak tree

66
Q

Name the tertiary consumer in the following food chain:

oak tree → caterpillar → blue tit → sparrowhawk

A

sparrow hawk

67
Q

What name is given to the organism at the top of the food chain that is not eaten by other organisms?

A

apex predator

68
Q

What term means organisms depend on each other to survive, grow and reproduce?

A

Interdependence

69
Q

What do you call a group of the same species (type) of organism living in an area?

A

population

70
Q

If the oak tree was sprayed with pesticide, explain which organism would have most pesticide inside them.

oak tree → caterpillar → blue tit → sparrowhawk

A
  1. sparrowhawk
  2. because of bioaccumulation
  3. caterpillar eats lots of oak leaves and absorbs pesticide
  4. blue tit eats lots of caterpillars and the pesticide build up (accumulate) inside them
  5. the sparrow hawk eats lots of blue tits to the pesticide builds up most inside the sparrow hawk
71
Q

What is a community?

A

Group of different species of organisms living together

72
Q

What is the name for the area in which an organism lives?

A

Habitat

73
Q

What is the name given to all the plants and animals living in an area?

A

ecosystem
