Biomes
This biome is characterized by hot arid climates and prolonged periods of drought
Deserts
This goes at the bottom of a food web
Primary Producers
Where does all energy come from in a ecological pyramid?
The Sun
What's the difference between a heterotroph and autotroph
Autotrophs make their own food, heterotrophs consume other organisms to get energy
Where do warm ocean currents originate?
The equator
This biome typically gets more than 30 feet of rain per year and is characterized by high levels of biodiversity
Tropical Rainforest
What direction does the arrow in a food web go?
From the organism being consumed to the consumer
What is a pyramid of numbers?
Number of individuals at each trophic level
What do decomposers do in an ecosystem
Recycle nutrients back into the ecosystem
What's the difference between population and community?
Population is all the same species, community is all the species living in an area
This biome is characterized by trees that drop their leaves in the fall/winter.
Temperate forest
What consumes primary producers?
Primary Consumers
How much energy is transferred from one trophic level to the next?
10%
What is an estuary?
Wetland that forms when the river meets the sea
What do enzymes do in chemical reactions?
Speed them up
This biome has permafrost, a frozen soil that only thaws for a few months out of the year and often remains frozen at depth making it hard for tall trees to grow
Tundra
What are the two types of producers we've learned about?
Photosynthesis and chemosynthesis
If primary producers provide 67% of energy into the ecosystem, how much energy do the secondary consumers get?
.67%
What's the difference between the independent and dependent variable?
Independent- I change it, thing we manipulate
Dependent- Thing we measure
Who won the first superbowl?
The Packers
This biome has large dark green coniferous forests that support a wide variety of grazers. It also has long cold winters and nutrient poor soils
Taiga/Boreal Forest
What are the 4 types of heterotrophs we've learned about?
Herbivores, omnivores, carnivores, detritivores
Which trophic level should have the most biomass to support an ecosystem?
Primary producers
What is the difference between the photic zone and aphotic zone
Photic= light reaches
Aphotic= no light
What year was MCHS built in?
1914
