a grouping of ecosystems with similar abiotic and biotic conditions
biome
period of dormancy animals enter when conditions are dry
estivation
deep, sleeplike state animals enter for most of winter
hibernation
below photic zone where no sunlight penetrates and photosynthesis cannot occur
aphotic zone
dense covering of trees 50-80 meters above the ground
canopy
areas nearest a river's course that are flooded periodically
flood plain
species of trees that produce seed-bearing cones
coniferous
soil that remains frozen year-round
permafrost
bodies of water, partly enclosed by land, that occur where fresh water from land drainage meets the water of an ocean or inland sea
estuary
plants that grow on other plants instead of in soil
epiphyte
areas of land that are flooded with water at least part of the year
wetland
the average conditions, including temperature and precipitation, over long periods in a given area
climate
the day-to-day conditions in Earth's atmosphere like "sunny and humid" or "cold and snowy."
weather
farther, from the shore where no rooted plants grow
limnetic zone
shorter trees and plants in a tropical rainforest
understory
diagram that shows an area's average temperature and precipitation
climatograph
the vertical flow of cold, nutrient-rich water toward the surface, occurs where horizontal currents flow away from each other
upwelling
trees that lose their leaves and stop photosynthesis during part of the year
deciduous
shallow near shore portion of the photic zone
littoral zone
tallest trees that pop through the canopy and make the top layer of the rainforest
emergent layer
organic matter, or biomass, that remains after cellular respiration
net primary production
In what year did the annual upwelling not occur?
2025
uppermost layer of an aquatic ecosystem , where there is enough sunlight for photosynthesis
photic zone
the amount of salt dissolved in water
salinity
very bottom of a body of water
benthic zone
