100
The scientific study of how organisms interact with their environment and all the other organisms that live in that environment
What is ECOLOGY
100
This is water in solid form.
What is ICE, HAIL or SNOW
100
The only living things that can use carbon dioxide
What are PLANTS
100
Makes up 78% of the air you breathe
What is NITROGEN
100
A substance made of two hydrogen atoms and one oxygen atom.
What is WATER
200
The release of water vapor and oxygen through a plant’s stomata.
What is TRANSPIRATION
200
This is needed for evaporation to occur.
What is HEAT
200
Over millions of years, carbon in the soil can become these
What are FOSSIL FUELS
200
No living things can use it when it is in the air.
What is NITROGEN
200
Our nickname for transpiration.
What is PLANT SWEAT
300
Plants absorb carbon dioxide from the atmosphere to make food for themselves.
What is PHOTOSYNTHESIS
300
This step of the cycle comes in the form of rain, snow, sleet, hail, or mist
What is PRECIPITATION
300
A plant uses this process to break apart carbon dioxide, then uses the carbon to make food, which supplies carbon to anything that eats the plant.
What is the IMPORTANCE OF PHOTOSYNTHESIS
300
The cycling of nitrogen through the atmosphere and through all living organisms.
What is the NITROGEN CYCLE
300
A series of events that happens over and over again.
What is A CYCLE
400
The burning of fossil fuels, which releases carbon into the atmosphere.
What is COMBUSTION
400
When water vapor cools and changes from a gas to a solid or liquid.
What is CONDENSATION
400
These three steps occur in the carbon cycle underwater and on land.
What are PHOTOSYNTHESIS, RESPIRATION, and DECAY
400
Two ways that nitrogen gas in the atmosphere is changed into nitrogen compounds that plants can use.
What are LIGHTNING, AND BACTERIA AND DECOMPOSERS
400
The nonliving parts of an ecosystem
What are ABIOTIC FACTORS
500
The process of combining nitrogen with other elements to form useful compounds
What is NITROGEN FIXING
500
These three processes all produce water vapor
What is EVAPORATION, TRANSPIRATION, and RESPIRATION
500
When carbons in the atmosphere, released by combustion, attach themselves to oxygen molecules.
What is CARBON DIOXIDE
500
Two elements that nitrogen bonds to to become usable during the nitrogen fixing process
What are CARBON AND OXYGEN
500
The living parts of an ecosystem
