100
some bacteria do this to nitrogen (but not lightning)
What is the way nitrogen gas is released from the nitrogen compound?
100
when producers use light energy to change carbon dioxide and water into sugar and oxygen
What is photosynthesis?
100
organisms that make their own food
What are producers?
100
many different species
What is biodiversity?
100
when a species dies out due to lack of resources, a change in global climate, or an increase in predators
What is extinction?
200
lightning and some bacteria
What are the 2 ways nitrogen gas is changed into a nitrogen compound?
200
the use of exygen and sugar to release energy and produce carbon dioxide and water
What is respiration?
200
herbivores and carnivores
What are comsumers?
200
the amount of biotic material by weight
What is biomass?
200
because the quagga mussels' were better adapted to life and outcompeted the zebra mussels for food
Why did the quagga mussels' population increase more than the zebra mussels' population?
300
decomposers do this
How are nitrogen coupounds returned to the soil?
300
the only species to give off oxygen
What are producers?
300
the transfer of matter and energy from one organism to another
What is a food chain?
300
the amount of food and space available in an ecosystem
What are limiting factors?
300
the possible effect of sudden climate global change
What is a sudden increase in the rate of extinction?
400
what nitrogen gas becomes when struck by lightning
What is a nitrogen compound?
400
they use respiration
What is almost all orgnaisms including producers?
400
a system of connected food chains in an ecosystem
What is a food web?
400
a group of one species of organism
What is population?
400
factors that provided the right conditions for the zebra mussels to spread in Lake Michigan
What is a rich source of algae and few predators?
500
the nitrogen cycle in detail
What is nitrogen gas being struck by lightning or bacteria changing it to a nitrogen coumpoud in the soil, then being taken in through the plant roots and changed to protein, then being eaten my consumers, then eaten by other consumers, then dying and being turned back into nitrogen compounds by decomposers?
500
the carbon dioxide / oxygen cycle
What is the cycle of oxygen being released from producers and used by consumers then the consumers releasing carbon dioxide that will be used by producers?
500
how light affects the life of an apex predator
What is light being used for photosynthesis which produces sugars in the producers, which are eaten by consumers, which are eaten by other consumers up to the top of the energy pyramid?
500
when resources are stored for a period of time so it is not cycling through the ecosystem (an example would be soil humus storing carbon so it does not cycle through the carbon dioxide/oxygen cycle)
What is a sink?
500
how mussels invaded Lake Michigan
What is taking in mussel infested water in the ship's ballasts in Europe then releasing the water and mussels into Lake Michigan?
