Question 1

WHY IS CARBON DIOXIDE

Answer 1

IS IMPORTANT BECAUSE IT IS NEEDED IN THE PROCESS OF PHOTOSYNTHESIS TO PRODUCE GLUCOSE AND OXYGEN

AND ITS IMPORTANT AS IT IS A GREEN HOUSE GAS MEANING IT KEEPS THE EARTH WARM

Question 2

WHY IS CARBON IMPORTANT

Answer 2

Every living organism has carbon compounds inside each of its cells,such as fats and proteins.

Answer 3

PHOTOSYNTHESIS IN PLANTS AND ALGAE

DISSOLVING IN THE OCEANS

Question 4

WHAT HAPPENS TO CARBON DIOXIDE DISSOLVED IN OCEANS

Answer 4

• IT REACTS TO FORM CARBONATES THAT ARE USED TO MAKE SHELLS
• OVER MILLIONS OF YEARS BECOME LOCKED UP IN SEDIMENTARY ROCKS

Answer 6

CARBON IN THE OCEAN FORMS CARBONATES IN SHELLS

CARBON IS STORED IN FOSSIL FUELS

TRANFERRED ALONG A FOOD CHAIN

DEAD ORGHANISM AND WASTE TRANSFER CARBON TO THE SOIL

Question 7

WHAT RELEASES CARBON DIOXIDE INTO THE ATMOSPHERE

Answer 7

CELLULAR RESPIRATION- A CHEMICAL PROCESS THAT USES GLUCOSE FROM FOOD AS FUEL TO PROVIDE ENERGY FOR LIFE PROCESSES

Question 8

CARBON DIOXIDE IS RELEASED INTO THE ATMOSPHERE WHEN..

Answer 8

PLANTS RESPIRE

BY THE COMBUSTION OF FOSSIL FUELS

AND BY DECOMPOSTION OF THE DEAD AND DECAYING MATTER
