UNIT 20-22 EXAM REVIEW 7 TH G R A D E WHICH ECOSYSTEM WOULD INCLUDE JACKRABBITS, CACTUS AND RATTLESNAKE? A Desert WHAT ECOSYSTEM IS THE COLDEST OF ALL AND NO TREES LIVE HERE? A Tundra. WHAT ECOSYSTEM HAS MORE BIODIVERSITY THAN ALL OTHERS? Tropical Rainforest. MOSSES ARE ONE OF THE FIRST SPECIES TO GROW ON BARE ROCK, WHY IS THE ENVIRONMENT WELL SUITED TO THESE PLANTS? They are small, less complex, and don’t require soil. WHAT PROOF OF ECOLOGICAL SUCCESSION DID WE NOTICE IN OUR GARDEN? Growth of weeds and grasses. WHAT COULD WIPE OUT A DEVELOPING FOREST INTO A GRASSLAND/SAVANNAH? Forest Fires WHAT TYPE OF SPECIES IS RESPONSIBLE FOR STARTING SUCCESSION IN AN ECOSYSTEM? A pioneer species which must be a species that goes through photosynthesis 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. AS HUMAN POPULATIONS INCREASE, WHAT IS HAPPENING TO THE AREA OF RAINFORESTS? They are decreasing and reducing the biodiversity in those areas being destroyed. 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. 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 IF ONLY THE LOWEST LEVEL OF A FOREST WAS DESTROYED BY A WILD FIRE, WHAT ORGANISMS WOULD BE MOST AFFECTED? The organisms that live on the ground and rely on the smaller plants near the ground. WHAT WOULD HAPPEN TO THE ORGANISMS THAT LIVED ON THE FLOOR OF THE FOREST IF A WILD FIRE DESTROYED THEIR HABITAT IF ONLY THE LOWEST AREA WAS AFFECTED? They would need to move to a different area to find food and possible shelter. WHAT TYPE OF BIOME IS COLD AND IS FULL OF TREES THAT STAY GREEN ALL YEAR LONG (LIKE CHRISTMAS TREES)? Coniferous Forest or Tiaga WHICH ORGANISMS ARE GOING TO LIVE IN A DECIDUOUS FOREST? Deer, squirrels, chipmunks, trees that lose leaves in the fall WHAT AREA OF THIS POND HAS THE GREATEST AMOUNT OF DIVERSITY? On the edge of the lake around the perimeter, including the sand, water, plants and rocks.
