CARBON CYCLE QUESTIONS!

  • Where is carbon found?

  • What gas in the atmosphere has carbon in it?

  • What 3 things make up the tissues of all living things?

  • What organisms make these substances by photosynthesis? What are these organisms classed as?

  • How do consumers get carbon?

  • What do decomposers eventually break things into?

  • How is carbon released into the air by organisms?

  • Why do living things need carbon?

  • What 2 things are humans doing to create more carbon in the atmosphere?

  • The amount of carbon dioxide in the atmosphere is i________________, which is adding to the G___________ Effect, keeping the planet warm and adding to g__________ w_____________.

  • What are 2 examples of fossil fuels?

  • What are two things we can do to decrease the amount of carbon dioxide in the atmosphere?


Answers
Answers…

  • In all living things – the main material in sugars, proteins and fats.

  • Carbon dioxide

  • Sugars, proteins, fats

  • Green plants, producers

  • By eating plants

  • Eventually into carbon dioxide

  • Respiration, as CO2

  • For the building of sugars, proteins and fats

  • Rapid human population growth, increased combustion of fossil fuels (for heat, electricity, petrol)

  • Increasing, Greenhouse, global warming

  • Coal, oil

  • Plant more trees, car pooling (less petrol)……


Nitrogen cycle
NITROGEN CYCLE!

Wherever there is an empty box, label it with one of the following:

Nitrogen in the atmosphere

Lightning makes nitrates

Eaten by animals

Nitrogen in plant protein

Decay by decomposers

Death

Nitrogen in animal protein

Nitrogen-fixing bacteria in soil and on root nodules

Other soil bacteria

Nitrates in soil

Nitrogen in animal protein

Divide paper into 3 bits:

  • What did you understand?

  • What did you not understand?

  • What did you find interesting?

    Then put in the correct bag up the front….
