Wyatt 1 If squirrels are the primary food source for hawks in an area and due to a drought the squirrels left the area. What result would most likely happen to the hawks? 2 Hibernation, migration and dormancy are all methods of animals 3 In an aquatic ecosystem, if the water level dropped due to drought, which aquatic population of animals would be most affected 4 An external stimuls that causes a plant to bend towards it 5 Phototroptism 6 How are dormancy and hibernation similar? 7 What would cause a species to move? 8 Nocturnal 9 Eutrophication 10 What is the result if there is an overpopluation of bacteria caused by an algae bloom? 11 If a species could no longer find food, what would it most likely do? 12 What is the effect of excessive use of nitrogen based fertlizers that run off into ponds and lakes? 13 Benefits of hibernation The hawks would follow the squirrels to a different area there is a reduction in oxygen levels a light source animals that are active at night and sleep during the day move to a new area to find food When a pond/lake is covered with algae and oxygen levels drop. Metabolic rate and body temperature both decrease It increases the rate of algae growth causes a responding plant to grow in the direction of light adapting to changes in the environment Environmental conditions have changed it reduces the need an animals has for food when resources are limited fish
