What is a food web?
100
An organism that eats both plants and animals
What is an omnivore?
100
A lion eating a zebra represents this type of relationship 
What is predation?
100
Soil, sunlight, O2, CO2, and temperature are all examples 
What are abiotic factors?
100
A characteristic that makes an individual better suited to its environment may eventually become common in that species through a process called
What is natural selection?
200
AN organism that cannot make its own food and gets energy by eating other organisms
What is a consumer?
200
Normally near the top of a food chain, these animal only consume other animal?
What is a carnivore?
200
A bird eating the flies off of a mule represents this type of a relationship
What is mutualism?
200
The primary difference separating a tropical rain forest from a grassland is this factor
What is precipitation?
200
Natural selection results in these, which are physical and behavioral changes organisms make to survive
What are adaptations? 
300
This process involved producers (autotrophs) taking in CO2 and H20 with sunlight to produce food energy (in the form of glucose and 02.
What is photosynthesis?
300
The absolute "top" of any food web
What is a top consumer? 
300
In the desert, a Saguaro is often used as a place to build nests for its bird population
What is commensalism?
300

300
The animal that is killed through predation
What is prey?
400
All of the members of one species living in a given area
What is a population?
400
All food webs begin at this level where sun (solar) energy is synthesized into food energy
What is a producer?
400
Carpenter ants eating their way through a Joshua Tree destroying its interior would represent
What is parasitism?
400
Eliminating a predator from a particular ecosystem could lead to the prey increasing its numbers too far 
What is overpopulation?
400
The negatively affected organism in parasitism 
What is a host?
500
The non-living parts of an ecosystem 
What are abiotic factors?
500
Normally called the primary consumer, these animals only eat plants
What is a herbivore?
500
Multiple populations inside an ecosystem have to generate enough space, food, and water to survive 
What is competition?
500
All organisms play specific roles in environments - what they eat, how they live, and where they are. These formulate an organism's this...
What is a niche?
500
