Q

What is the Maori Creation Myth?

A

There was Ranginui (sky father) and Papatuanuku (earth mother) came to be. They had male children that lived between them. These brother wanted to see light and have more space. So, Tanemahuta (god of forest) separated his parents. Tawhirimatea (god of wind) was mad so he joined his father. To this day we can see Ranginui sadness from rain. Pap sadness from volcanoes and mist. Tawhirimateas anger from wind and tornados.

Q

What are the tropic levels?

A
  1. Producer
  2. Primary consumer
  3. Secondary consumer
  4. Tertiary consumer
  5. Apex Predetor
20
Q

What is the main source of energy for the producer?

A

Sunlight:
Sunlight is the main source of energy obtained by the producer through photosynthesis.

21
Q

Describe how energy is transfered in a food chain?

A

Energy from sunlight is transfered 1% to the producer through photosynthesis. Then producer transfers 10% of their energy to the consumer and so on. So, only 10% of the energy is consumed and passed up on the foodchain from producer to all the consumers.

22
Q

Why is energy is lost through a food chain?

A

10% of the energy is passed through the consumer that eats the organism. But the rest of the energy is lost due to metabolic processes and other biological activities like movement,respiration, waste products and heat.

23
Q

State the meaning of arrows in the food chain?

A

Arrows represent the direction the nutrients and energy is passed through as ecosystem.

24
Q

What is an Habitat?

A

An habitat is where an organism lives that has all the things it need to survive.

25
Q

What is Abiotic and Biotic Factors?

A

Biotic is the living things or living things in an ecosystem.

Abiotic is the non-living things in an ecosystem.

26
Q

What are some examples of Biotic Factors?

A

Humans, animals,predators, bacteria, food.

27
Q

What are some abiotic factors?

A

Temperature, water, sun, soil, nutrients, light intensity,

28
Q

What is adaptation?

A

Adaptation is the process where the species evolves characteristics that helps them to survive/adapt in a specific environment.

29
Q

What is Physical & Behavioural adaptations?

A

Physical adaptation is the physical characteristics of an organism. It is an changing feature of an living thing. Like fur, sharp claws, camouflage…

Behavioural adaptations is things that living things do to survive in a specific environment. Such as the way the move, feed, breed.

Like bear hibernating, birds migrating

30
Q

What are adaptations needed for predators?

A

Sharp teeth, claws, strong legs so it can run fast.

31
Q

What are good adaptations for prey?

A

Prey’s adaptations is to try and hide, to protect from their predators. Like, camouflaged, good senses,

32
Q

Scientific Name for Dogs/wolves

A

Cannis

33
Q

Scientific name for cats/tigers

A

Panthera

34
Q

What is sustainability?

A

Sustainability is meeting our own needs without comprimising the future generation to meet their needs.

35
Q

What is Bycatch?

A

By catching is the process where additional unwanted marine organisms are caught while fishing using nets. So, by the time the fishermen realise these organism, so might already be dead or harmed. So, bycatch disturbs the ecosystem.

36
Q

Name 3 Sustainable Fishing Methods.

A
  1. Traps
  2. Hooks
  3. Harpoons
37
Q

What is overfishing?

A

Overfishing is fishing additional or large amount of fish at a time, when it is’t essential. This cause the marine life population to decrease significantly. As constant overfishing means the number of sea life keep on decreasing so there won’t have time for reproduction to fix this issue.

38
Q

How is Hook, harpoon, traps sutainable fishing methods?

A

These are sutainable fishing methods because these techniques only focus on fishing for one or small group of fish. This means this techniques prevent overfishing. And, they have a traget for bycatch won’t happen. Therefore, these mean the fish population won’t decrease as much so that the future generation can still use it.

39
Q

What are polymers?

A

Polymers are large molecules build up on small units called monomers, through polymerisation.

40
Q

What are plastic made out of?

A

Plastics come under the classification of polymers that consist of many polymeric chains. Majority of these polymers are from crude oil. Which is converted to pertrol and other gasoline from fractional distillation.

41
Q

What is Thermosetting Plastic?

A

Thermosetting plastic can only be heated and shaped once. If reheated they cannot be soften as the polymer chains are interlinked. It can’t be used more than once.

42
Q

What is Thermoplastics?

A

Thermoplastics can be heated and shaped many times. Because there are no links between the polymer chains.

43
Q

What is Micro-plastic?

A

Micro-plastic are tiny plastic particles that are result of large plastic items being broken down by environmental factors.

44
Q

Give 3 examples of micro-plastic?

A
  1. Small particles of larger plastic product, (bottle)
  2. Clothing- Fibres
  3. Microbeads
45
Q

What is the problem with plastic?

A
  1. Production require petrol (non-renewable)
  2. Eaten by willife

3.Takes too long to degrade
