superficial treatment of a large number of points.


Do not worry we will practice this method of writing an essay to get maximum marks.

There are always three essays to choose one from.
Biomes –
Here are some web sites where you can do some further investigation of soils and biomes.

Introduction to Biomes.
Remember the questions from the start of the previous section.

  • Describe how plant and animal life adapt to soil and climatic conditions in a biome which you have studied.

  • Assess the impact of human activity on a biome that you have studied.

  • Examine the main characteristics of a biome that you have studied.

  • Assess how biomes have been altered by human activity.

Answering the Option Question is different to the other answers



  • The option answer is an essay type answer

  • Usually the marking scheme looks for three aspects to be discussed

  • Therefore within the answer there should be three main paragraphs = 80/3 = 27 +27+26

  • Each paragraph is worth 27 marks, broken up as follows –

Identifying aspect - 4 marks

8 x SRP’s 16 marks

Cohesive structure/well written 7 marks

Total per paragraph 27 marks


Biome - Definition


  • The biome is the largest ecosystem unit

  • Each biome takes its name from the dominant type of vegetation found within it.

  • Usually climate has been the major controlling factor – though economic development has changed many of the natural systems

  • There are four main factors which combine to produce each biome

      • Climate

      • Soils

      • Natural Vegetation

      • Animal Life

  • Examples of biomes include

For the purpose of this section, we will study a Desert Biome. This is the biome that is found a portion of the South West US region.
