  1. 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?

  2. 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)……

  3. 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

  4. nitrogen in the atmosphere lightning makes nitrates Nitrogen in animal protein eaten by animals Nitrogen in plant protein Other soil bacteria Nitrogen-fixing bacteria in soil and on root nodules death decay by decomposers nitrates in the soil NITROGEN CYCLE!

  5. 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….
