Anything Goes
100
This consists of all life on Earth and all parts of the Earth in which life exists.
What is the biosphere?
100
Organisms that use solar or chemicals to convert it into forms that living cells can use are called this.
What are autotrophs or producers?
100
This is a series of steps in which organisms transfer energy by eating and being eaten.
What is a food chain?
100
Unlike the one-way flow of energy, matter is ...
What is recycled?
100
This cycle continuously moves between the oceans, the atmosphere, and land- sometimes outside living organisms and sometimes inside them.
What is the water cycle?
200
This is a group of individuals that belong to the same species and live in the same area.
What is a population?
200
These are the first producers of energy-rich compounds that are later used by other organisms.
What are primary producers?
200
This is a network of feeding interactions and is consisted of several food chains in an ecosystem.
What is a food web?
200
These are closed loops that show how elements pass from one organism to another in parts of the biosphere.
What are biogeochemical cycles?
200
This is when bacteria fix nitrogen by turning it into ammonia.
What is nitrogen fixation?
300
This is an assemblage of different populations that live together in a defined area.
What is a community?
300
These organisms must acquire energy from other organisms, by ingesting them in one way or another.
What are heterotrophs or consumers?
300
Each step in a food chain or food web is called this.
What is a trophic level?
300
The three pathways or cycles that move nutrients through the biosphere are these...
What are carbon, nitrogen and phosphorus cycles?
300
This is the kingdom both phytoplankton and zooplankton would be categorized into.
What is "protists"?
400
This includes both abiotic and biotic factors because it includes all the organisms that live in a place, with their physical environment.
What is an ecosystem?
400
This is a process where chemical energy is used to produce carbohydrates.
What is chemosynthesis?
400
These are pyramids that show the relative amount of energy available at each trophic level of a food chain or web.
What is an energy pyramid?
400
This is a nutrient whose supply limits productivity.
What is a limiting nutrient?
400
This is a type of consumer who digest decomposers that live on, and in , detritus particles.
What are detritivores?
500
This is how muck is considered abiotic, yet very influenced by biotic factors.
What is it is made of dirt and water, but contains fungi, bacteria and decomposing plant matter?
500
This is a type of consumer that feed by chemically breaking down organic matter.
What is a decomposer?
500
On average, this is how much energy transfers from trophic level to trophic level.
What is 10%?
500
This is an area of the biosphere that is extremely nutrient poor.
What is the open ocean?
500
The hyena, grizzly bear and even bald eagle are this special type of consumer.
What is an opportunistic feeder?
