What is all of the living and non-living things that interact in a particular environment. They can be as small as a pond or as large as a forest or desert.
What is an ecosystem?
100
These show simple connections between biotic factors in an ecosystem
What is a food chain?
100
a series of events that happens over and over again.
What is a cycle?
100
These are the two ways that plants and animals create energy and depend upon each other
What are respiration and photosynthesis?
100
These are the three main cycles that affect living things
What are the water, carbon and nitrogen cycles?
200
Non-living things in an ecosystem
What are abiotic factors
200
Light, soil, temperature, and water
What are abiotic factors?
200
This involves evaporation, respiration, and precipitation to list a few
What is the water cycle?
200
The decay of once-living organisms creates these
What are fossil fuels?
200
This makes up 4/5 of the air that you breathe
What is Nitrogen?
300
Root word "ecos"
What is "house?"
300
Microbes that live in this fix nitrogen
What is the soil?
300
Is the release of water by plants
What is transpiration?
300
Humans do this to make everyday items. It releases Carbon into the atmosphere and is usually done with fossil fuels
What is combustion?
300
Nitrogen in the air gets "fixed" by this
What is lightning?

What are biotic factors in an ecosystem?
400
All living things need this to carry out life processes
What is water?
400
Is the cooling of gas to form a liquid
What is condensation?
400
This is a gas that is building up in our atmosphere and contributing to global climate change
What is CO2?
400
These are the greatest source of nitrogen-fixing
What are bacteria?
500
How biomes relate to ecosystems.
What is a large network of ecosystems?
500
Photosynthetic organisms use this to create food energy (chemical energy) for all of the other living things in an ecosystem
What is light?
500
The by-products of this process includes CO2 and water vapor and is how animals make energy in their bodies
What is respiration?
500
Marine organisms use carbon to build these for protection at the bottom of the ocean
What are shells?
500
These (bacteria) are located in the soil and help break down dead organisms
