Difference between producers and consumers?
What is producers make their own food, consumers "eat" others to get food
100
What is a food web?
What is Network of interconnected food chains
100
What is GPP?
What is gross primary productivity (GPP) the rate of an ecosystem’s producers converting energy as biomass

What are the major parts of the water cycle?
What is Evaporation Precipitation Transpiration

What are the four major componets of earth's life support system?
What is The four major components of the earth’s life-support system are: the atmosphere (air) hydrosphere (water) geosphere (rock, soil, and sediment) biosphere (living things).
200
What is the end product of photosynthesis?
What is glucose (carbs/sugars)
200
What is biomass?
What is Dry weight of all organic matter of a given trophic level in a food chain or food web
200
What is NPP?
What is Net primary productivity (NPP) rate which producers use photosynthesis to store biomass minus the rate which they use energy for aerobic respiration.
200
How do humans impact the water cycle? (Name one)
What is Withdrawal of large amounts of freshwater at rates faster than nature can replace it Clearing vegetation Increased flooding when wetlands are drained
300
What three things/ideas support life?
What is the flow of energy from the sun through the biosphere the cycling of nutrients within the biosphere Gravity (holds Earth’s atmosphere)
300
Define omniovores, carnivores and herbivores
What is eat both plants/animals, eats animals, eats plants
300
What does the pyramid of flow of energy show?
What is The pyramid of energy flow visualizes the loss of usable energy through a food chain.
300
Three most productive NPP ecosystems?
What is The three most productive systems are: swamps and marshes tropical rain forest estuaries.
300
Two ways humans impact the nitrogen cycle?
What is Additional N in atmosphere from burning fossil fuels; also causes acid rain N to atmosphere from bacteria acting on fertilizers and manure Destruction of forest, grasslands, and wetlands Add excess nitrates to bodies of water Remove N from topsoil
400
Difference between abiotic and biotic?
What is living and non-living
400
what role do decomposers play?
What is release nutriets back into the "cycle"
400
How much energy is lost moving up in trophic levels?
What is Approximately 90% of energy lost with each transfer; Less chemical energy for higher trophic levels
400

What are the five levels of organization?
What is organism, population, community, ecosytem and biosphere
500
Relate movement of energy, the food chain and the 2nd law of energy
What is there is a decrease in the amount of energy available to each succeeding organism in a food chain or web.
500
What level of a food chain, supports the most amount of people (top or the bottom)?
What is bottom---producers
500
What is a soil horizon?
What is the different layers of soil...example o horizon or a horizon

What is leaching?
What is Water moving downward dissolves minerals and organic matter and carries them to lower levels; this process is leaching.
