6. WHAT PROOF OF ECOLOGICAL SUCCESSION DID WE NOTICE IN OUR GARDEN? Growth of weeds and grasses.

7. WHAT COULD WIPE OUT A DEVELOPING FOREST INTO A GRASSLAND/SAVANNAH ? Forest Fires

8. WHAT TYPE OF SPECIES IS RESPONSIBLE FOR STARTING SUCCESSION IN AN ECOSYSTEM ? A pioneer species which must be a species that goes through photosynthesis

9. IF A NON NATIVE PLANT IS INTRODUCED INTO A DIVERSE MATURE ECOSYSTEM, AND IT HAS NO NATURAL PREDATORS, HOW WILL IT AFFECT THE COMMUNITY ? It will grow more and reduce the amount of native species.

10. AS HUMAN POPULATIONS INCREASE, WHAT IS HAPPENING TO THE AREA OF RAINFORESTS? They are decreasing and reducing the biodiversity in those areas being destroyed.

11. WHEN A FOOD WEB HAS MANY ORGANISMS AS THE ONE TO THE RIGHT, WHAT HAPPENS TO THE SUSTAINABILITY OF THE ENVIRONMENT? This leads to a more sustainable ecosystem.

12. IF TWO CORALS COMPETE AGAINST EACH OTHER IN A REEF, AND AN INCREASED TEMPERATURE IN ONE YEAR CAUSES THE RED CORAL TO DIE OUT WHILE THE ORANGE CORAL IS UNAFFECTED, WHAT HAPPENS IF THE TEMPERATURE REMAINS HIGH EVERY YEAR? The orange coral would eventually take over the entire reef
