The information collected during an experiment or research project.
What is data?
100
All living things are made up of small units called these.
What are cells?
100
The study of the interactions among living systems in the environment.
What is ecology?
100
Producers, such as plants, that capture energy from the environment for food.
What are autotrophs?
100
Any living relationship between two different species.
What is symbiosis?
200
An educated guess or statement.
What is a hypothesis?
200
All living things produce new offspring through this process.
What is reproduction?
200
An individual living thing...may be made up of organs.
What is an organism?
200
Fungi and bacteria are examples of these heterotrophs that break down organic matter for food.
What are decomposers?
200
The full range of living conditions an organism has and how that organism uses those conditions. "How ya livin' homie?"
What is niche?
300
The variable that is observed in response to the controlled (manipulated) variable.
What is the dependent variable?
300
Living things that are comprised of more than one cell are called this.
What is multicellular?
300
The part of earth that contains all the ecosystems.
What is the biosphere?
300
A complex interaction of feeding relationships found in an ecosystem, usually consisting of several food chains.
What is a food web?
300
Symbiotic relationship where one organism hurts or harms a host for their own benefit.
What is parasitism?
400
A well tested explanation that covers a broad range of observations on one subject.
What is a theory?
400
The breaking down of material (food) through a series of chemical reactions in the body. This provides energy for the body.
What is metabolism?
400
Populations that live together in a defined area.
What is a community?
400
Each step in a food chain, each level of an ecological pyramid.
What is a trophic level.
400
During ecological succession, these guys are usually the pioneer species...the first to appear in the area.
What are the autotrophs or producers?
500
Numerical data collected during an experiment is also called this.
What is quantitative data.
500
A process by which an organism will keep internal conditions fairly constant, despite changes in the environment.
What is homeostatsis?
500
Nonliving factors that play a role in the ecosystem.
What are abiotic factors?
500
The apporoximate amount of energy available in one trophic level that can be transferred to the next level.
What is 10%?
500
Symbiotic relationship that exists between a bumblebee and a rose plant.
What is mutualism?
