Location: mild climates Temperature: 6-28°C or 43-82°F Precipitation: 75-125 cm or 30-49 inches per year -Many broadleaf trees like Oaks and Maples that drop their leaves each fall -Has four seasons: summer, fall or autumn, winter, and spring -Animals are extremely adaptive to deal with changing seasons -Plants like mosses, ferns, and grasses grow under trees ã2019 Black-Eyed Susan Science Location: between forest & desert Temperature: Summer: 30°C or 86°F Winter: 0°C or 32°F Precipitation: 25-75 cm or 10-30 inches -Main types of plants are grasses, too dry for trees -Home to many grazing animals A Savanna is a grassland with few scattered trees. In Australia, they are home to kangaroos and wombats; in Africa, giraffes and elephants. ã2019 Black-Eyed Susan Science Location: dry environments Temperature: can reach over 38°C or 100°F Precipitation: less than 25 cm or about 10 inches/ a year -organisms must be able to survive in dry regions -typical plants: cacti, bushes, small flowering plants -animals eat seeds and other parts of plants -small animals are prey for snakes and vultures -animals are mainly nocturnal: active at night ã2019 Black-Eyed Susan Science The ocean is divided into three zones of life. Water temperature, pressure, and sunlight\ differ in each zone. Intertidal Neritic Open- ocean Intertidal Zone -shoreline areas covered by water at high tide, but not at low tide -home to many shelled animals Neritic Zone -few-200 meters deep -home to algae, plankton, fish, plants, clams, lobsters, and sponges Open-ocean Zone -largest area, but fewest organisms ã2019 Black-Eyed Susan Science -Includes lakes, ponds, swamps, streams, and rivers Lakes & Ponds - Plants may grow along edge. Algae, fish, and amphibians live here. Animals live near edge and visit to get water and food. Rivers & Streams - Swift moving water home to many fish, birds, insects, and larvae. Larvae – young mosquito Adult insect - mosquito ã2019 Black-Eyed Susan Science
