 Below is everything the examiners think you know, if you're not sure of something click on the link to watch my YouTube video explanation. For a copy of these you can print off, get the FREE revision guide I wrote for you.


 • I can give the meaning of each of the following: ecosystem, biodiversity, conservation.

 • I can name and describe the location of two contrasting ecosystems.

 • I can describe how farming methods can damage an ecosystem.

 • I can describe and locate one ecosystem that is being managed.

 • I can explain why food production methods change natural processes (like nutrient cycles) in an ecosystem.

 • I can give reasons why energy or water resource production can have negative impacts on the environment.

 • I can explain why sustainable management of food production is necessary in hot semi-arid grassland regions.

 • I can explain links between local scale damage to ecosystems and wider regional consequences.

 • Using the case study of one ecosystem you have studied, write a balanced summary of trends and changes shown in evidence and data.

 • I can use sources such as table/graph/photograph/map to analysis the damage to ecosystem stability.

 • I can select reliable data to highlight impact of food production on the environment.

 • I can use evidence to demonstrate how poor land management has affected one region of hot semi-arid grassland. Looking at your case study, evaluate the outcomes of local scale conservation strategies. Explain why decisions to increase food production or energy production in vulnerable areas are difficult.

 • I can use evidence to make recommendations on how a named ecosystem should be managed.

 • I can use evidence to argue why sustainable management strategies are necessary in hot semi-arid grasslands.

 • I can use evidence to shape an argument for sustainable conservation in a named ecosystem.
