Make a list of 5 ABIOTIC factors for a pond

2. TASK: What would be the impact on the ecosystem if the Dragonfly were to go extinct (3 marks)

3. Challenge – Describe what nutrient cycling is
A set of processes whereby organisms extract minerals necessary for growth, from soil or water, before passing them on through the food chain, and ultimately back to the soil and water.

4. Task – Draw out just the TREE part of your rainforest case study diagram

5. Amazon Rainforest – Tree Part
You need to know:
Epiphytes
Buttress roots
Lianas
Smooth bark
Drip tips
Leaves falling 365 days a year to replenish soil- as leaching occurs.

6. Using figure 1 explain how animals have adapted to the rainforest ecosystem (3 marks)

7. TASK: Have a look at the answer provided and give a predicted mark out of 6
Using your own knowledge and the figure explain how tropical rainforest vegetation has adapted to the physical conditions (6)
In Figure 2 there are many different plant adaptations shown. The tree has buttress roots, which support the tree due it growing very high to reach the sunlight. The roots of the plants in the rainforest are shallow due to the nutrients being high to the surface. The plants have drip tip leaves. These are important due to the high amount of rainfall which could cause the plants to drop their leaves. With a drip tip, the water runs off. Rainforest vegetation also includes things such as lianas and epiphytes that use the larger trees as a way of supporting themselves to survive in the rainforest.

8. Underneath your copy of this answer, develop it from L2 to L3.
AQA feedback
Accurate knowledge is displayed with reference to buttress roots, drip tip leaves and bark. There is explanation of these features but not enough detail for L3. You need links to the climate.
Challenge:
Underneath your copy of this answer, develop it from L2 to L3.
Refer to:
The purpose of getting to sunlight (to photosynthesise)
How the lianas and epiphytes are adapted
The implied damage to the leaves could also be clearer and more precise.
