1.33-34. The Carbon And Nitrogen Cycles

Question 1

What will happen to the carbon compounds an organism gains when it consumes a plant containing carbohydrates, fats and proteins?

Answer 1

Some of the compunds are broken down during digestion and taken into the body.
The test will leave the body as faeces.

Question 2

What happens then to the carbon compunds taken into the animals body?

Answer 2

Some of the carbon compounds will be used for resperation and some may form waste products that are excreted in urine.

The rest are used to make more complex compunds inside the animal and make more animal biomass.

Question 3

1. Worms and fly larvae (maggots) are examples of…

2. Bacteria and fungi are examples of…

Answer 3

1.Detritus feeders.
2.Decomposers.
Start the process of decay by feeding on dead animals and also feed on feaces.

Question 4

Which process release carbon dioxide into the atmosphere?

Answer 4

Combustion of fossil fuels.

Respiration from living organisms.

Question 5

Which process removes carbon dioxide from the air?

Answer 5

Photosynthesis.
During this process the Carbon dioxide will be transformed into glucose.

The plant may use the glucose for resperation in which case the carbon will be released back into the atmosphere.

Otherwise, the glucose may be changed into other carbon compounds and used to make more plant biomass.
