A student made a model ecosystem in a bottle like the one shown below. Then the student wrote the following sentence in her journal: "If the water cycle occurs in my model, then I will see condensation on the side of the bottle."
The student's statement represents the ___________________ of the experiment.
What is a hypothesis?

The water flowing in a river moves at different speeds. The picture below shows what happens to a river overtime. At which speed does the river deposit the most sediment?
What is where the water moves the most slowly?
100
Pine needles, seaweed, bear, humans, etc.
What are biotic factors?
100
The point at which the populations in the graph level off.
What is the carrying capacity?
100
Large, moving pieces of Earth's crust.
What are tectonic plates?
200
The best empirical evidence of the cycling of carbon dioxide in the terrainium shown below.
What are healthy plants?
200
A low area of land often formed between hills or mountains caused by erosion from a stream.
What is a valley?
200
A group of organisms that live together in the same area at the same time and interact with one another (largest group in a given area).
What is a community?
200
A snake eating a mouse in a cornfield is an example of this.
What is predation?
200
An identification tool in which each step offers two or more choices, and each choice leads to a different path of subsequent choices.
What is a dichotomous key?
300
Feral cats kill large numbers of native wildlife in Australia. One feral cat can kill up to 50 native animals in one night. This technology would require environmental scientists to directly interact with the cats but also let them know exact locations of the individual cats at all times.
What is global positioning systems (GPS)?
300
Erosion by water and gravity caused this famous landform.
What is the Grand Canyon?
300
The matter that makes up living things and that contains carbon compounds.
What is organic matter?

300
The death of an entire species.
What is extinction?

The study of plants.
What is botany?

The direction wind tends to move.
What is from areas of high pressure to areas of low pressure?
400
The map below shows the location of Earth's principal biomes. These abiotic factors play important roles in tropical forests.
What are heat and humidity?
400
The organic matter produced by living organisms in a specific area.
What is biomass?
400
A physical or behavioral trait that improves an organism's chances of survival in a given environment or community.
What is an adaptation?
500
The study of relationships among organisms and between organisms and their environment.
What is ecology?
500
The direction in which the wind is likely to blow in the picture below.
What is from the ocean to the land?
500
A treeless expanse of land with permanently frozen subsoil.
What is the tundra?
500
A progressive series of changes in a community that results in its complete replacement by another community.
What is succession?
500
The process by which the traits of a population of organisms change over many generations.
What is evolution?
