Tropical rain forestHot and wet year round; home to more species than all other land biomes combinedtropical dry forestwarm year round; wet and dry seasons; tall deciduous trees, tigers, termitestropical savannawarm temperature; frequent fires; tall perennial grasses, herbivores such as antelopes and zebrasdesertvariable temperatures; low precipitation; cacti and other succulentstemperate grasslandwarm to hot summers, cold winters, fertile soil; perennial grasses, prairie dogstemperate woodland and shrublandhot, dry summers, nutrient- poor soil; woody evergreen shrubs, chaparral, coyotestemperate forestcold to moderate winters, warm summers, year round precipitation; deciduous trees, raccoons skunksboreal forestlong cold winters, short mild summers; needle leaf conifers, moose, lynxtundracold, dark, long winters, permafrost; mosses, lichens, sedges, caribou, musk oxWhat are the four main factors that affect aquatic ecosystemsdepth, flow, temperature, and chemistryWhat two categories do most freshwater ecosystems belong toflowing water and standing waterWhat are the ocean zones based on light penetration calledphotic and aphoticocean zones based on distance from land the depth of the ocean floorintertidal zone, coastal ocean, open oceanIntertidal zonesubmerged in seawater at high tide and exposed to air and light at low tide (rocks, barnacles, seaweed)coastal oceanBrightly lit and highly productive (kelp forest and coral reefs)Open oceanmore than 90% is open ocean. is divided into photic zone and aphotic zonephoticlow nutrient levels and smallest species of phytoplankton. Most photosynthesis occurs at the top of the photic levelsaphoticPermanently dark and deep part of the ocean. Chemosynthetic organisms.Comparing aquatic ecosystems zone, which would be considered the warmest in temperature?standing waterWhat contributes to the nutrient availability in aquatic ecosystems?Amount of nitrogen, oxygen and other elements dissolved in the waterAre you likely to find zooplankton in the aphotic, benthic zone of an ocean?noWhat are examples of freshwater ecosystem?Flowing water: rivers, streams, creek, brook
Standing water: lakes and pondsWhat are the freshwater ecosystem that often originates from underground sources in mountains or hills?Rivers and streamsWhat are some ways a freshwater wetland differs from a lake or pond?Water does not always cover a wetland as it does a lake or pond. Wetlands are salty, but lakes and ponds are fresh.A wetland that contains a mixture of fresh water and salt water is called?an estuaryEstuaries are commercially important because?they spawn a lot of offspring from organisms reproducingWhat are some factors that make estuaries unique?-it is where fresh water and salt water meet and a lot of organisms reproduce there -They have a lot of biomass but not a large variety of speciesWhat types of animals would be found in the biome that has cold to moderate winters, warm summers, and fertile soils and is home to a variety of vegetation, such as coniferous trees, broadleaf deciduous trees, flowering shrubs, and ferns?chipmunk, squirrel, insects, butterflies, bees, frogs, snakes, skunk, rabbit (Temperate forest)planktontwo types of plankton, Phytoplankto and zooplanktonzooplanktonsmall free floating organisms that forms part of planktonRiver/ streamsoriginate from underground water sources in mountains or hillsEsuaryWhere river meets seawetlandsan ecosystem in which water either covers the soil or is present at or near the surface for atleast part of the yearlakes/ pondsWater flows in and out and circulates. The circulation distributes heat, oxygen, and nutrients.greenhouse effectnatural situation in which atmospheric gasses trap heat inside earths atmosphere
