What is a producer?
The ultimate source of all energy in ecosystems.
What is the sun?
A wolf hunting and consuming a sheep.
What is predation?
A relationship in which both organisms benefit
What is mutualism
Example of ecosystem change over time
What are seasons? (More than one answer accepted)
The percentage of energy transferred from one trophic level to the next
What is 10%?
Essential for all organisms and affects where they can live.
What is water?
A linear sequence showing how energy and nutrients are transferred when one organism eats another
What is a food chain?

What is a food web?
A relationship where one organism benefits without harming the other
What is commensalism?
Something that restricts the growth and distribution of a population.
What is a limiting factor?
Breaks down dead matter and recycles nutrients
What is a decomposer?
Influences species survival by affecting metabolic rate and habitat stability
What is temperature?
All the populations of organisms living in a given place.
What is a community?
"Living together"
What is symbiosis?
What is a keystone species?
Energy that is not transferred to the next trophic level is transferred in these ways
What is heat loss, waste, or indigestible parts?
Essential for plant growth and recycled by decomposers
What are nutrients?
A community and its environment
What is an ecosystem?
Interaction types that are NOT symbiotic relationships
What are competition and predation?
