the average condition, including temperature and precipitation, over long periods in a given area
the day-to-day conditions in Earth's atmosphere, such as "hot and humid" or "cold and snowy"
a diagram that shows an area's average temperature and precipitation
net primary production
the organic matter, or biomass, that remains after cellular respiration
temperature and precipitation
Which abiotic conditions exert the greatest influence on biome classification?
the same biomes tend to occur at similar latitudes
What is the relationship between lantitudes and biomes located across Earth?
the dense covering of trees, so to 80 meters above the ground, in a rain forest
top layer of the rainforest canopy, made up of the tallest trees
the shorter trees and plants found in a tropical rain forest
a plant that grows on other plants instead of in soil
a tree that loses its leaves and stops photosynthesis during part of the year
the deep sleeplike state that an animal enters when conditions are dry
a animal that kills and eats other animals
a tree bearing cones that typically does not lose its leaves
the deep sleeplike state that an animal enters for most of the winter
permanently frozen soil
a measurement of the amount of salts dissolved in water
the uppermost layer of an aquatic ecosystem, where there is enough sunlight for photosynthesis to occur
the layer below the photic zone where no sunlight penetrates and photosynthesis cannot occur
the bottom layer of an aquatic ecosystem
the shallow rear-shore portion of the photic zone
the portion of the photic zone that is farther from shore than the littoral zone; no rotted plants are found in this zone
an area alongside a river that periodically floods
an area of land that is flooded with water at least sometime during the year
an ecosystem located where a river flows into the ocean, mixing fresh water with salt water
the flow of cold, nutrient-rich water toward the surface of the ocean
water salinity, depth, and whether the water is moving or standing
Identify three factors that characterize aquatic systems:
Where fresh and salt water mix in coastal estuaries, they form _______________________ ecosystems.
Freshwater estuaries tend to be diverse ecosystems with a mix of river and __________________ organisms.
Salt marshes stabilize shorelines against ___________________________.
tropical and subtropical
In _____________________________________ latitudes, mangrove forest are found along gently sloping, silty coasts.
The largest ______________________ in america are in Florida's everglades region.
They help prevent soil erosion and flooding. They are good for organisms to mate and to have offspring
State the ecological importance of estuaries:
open-ocean zone, Intertidal zone, Neritic zone
Identify three major ocean ecosystems:
climate, typical plant life, typical animal life
Which of the following characteristics are used to classify biomes?
mean monthly temperature
What data are shown on a standard climatograph?
In tropical rain forest, plants called ___________________ grow on other plants instead of soil. They take advantage of the host plan's height to get more sunlight.
Most trees in tropical dry forests are _________________, which means they lose their leaves and stop photosynthesis during part of the year.
Tropical regions with less rain than tropical dry forests, but more rain than deserts, are called __________________, or tropical grasslands.
In deserts, some animals avoid hot, dry periods by going into _____________; a sleeplike state of inactivity
thick, fire-resistant bark
What adaptations would most benefit plants that lived in an area with these conditions? (savanna)
tropical rain forest
Which biome would have the highest net primary productivity?
thick fur or blubber
