Question 5

Name two ways plants directly contribute to Co2 in the atmosphere and one way they reduce it

Answer 5

Resperation, combustion and reduce it threw photosynthesis.

Question 6

How do animals contribute to Co2 in the atmosphere

Answer 6

Resperation

Question 7

Describe oh fossils relate to the caebon

Answer 7

Plants and animals die and become dead organic matter. They then have a chance of becoming fossils and fossil fuel which are burned by humans

Answer 9

NH4

Question 10

Name the 3 ways Nitrogen gets fixed from the atmosphere

Answer 10

Lightning Nitrogen fixing bacteria, blue/green alge

Question 11

Name 3 ways Nitrogen gets fixed from the atmosphere

Answer 11

Blue/green alge, Nitrogen fixing bacteria, lightning

Question 12

What happens to nitrogen after the blue green alge fixes it

Answer 12

The alge is eaten by fish and the Nitrogen is turned into animal proteins

Question 13

What happens to nitrogen after it is fixed by bacteria

Answer 13

It is deposited into the soil and plant roots. From the plant roots it is turned into proteins which are then eaten buy animals and turned into animal proteins
