Ecosystems
The organizational level above ecosystem
What is biome?
Everything that is non living in an ecosystem is this
What is an abiotic factor?
The relationship when one organism consumes another
What is predator-prey?
the primary source of energy in most ecosystems
what is the sun?
The process by which rocks are broken down & moved to new places
What is weathering and erosion?
These organisms are primary producers in most terrestrial ecosystems
What are plants?
The relationship between you and a mosquito
What is parasitism?
If an organism consumes another organism that consumes producers, it is this level on an energy pyramid
What is a secondary consumer?
The primary energy conversion done when eating food
What is chemical to mechanical or heat
This cycle plays a large role in global climate change
A tree and everything living on it is an example of this level of organization
What is a community?
This relationship describes two species where one benefits while the other is neither helped nor harmed
These organisms are responsible for converting dead organic matter into inorganic nutrients
What are decomposers?
In a food chain, the percentage of energy that is typically transferred from one trophic level to the next
This process returns water vapor to the atmosphere
What is transpiration?
In a food web, this would most likely happen if all the primary consumers were removed
As you breathe, you return carbon to the air through this process
What is respiration?
The primary food source of sea otters in our previous activity
What is a sea urchin?
This happens to most of the energy at each trophic level
what is being lost as heat?
The process by which plants remove carbon from the air.
What is photosynthesis?
This can happen when species at the top of the energy pyramid suppresses another level in an ecosystem
What is a trophic cascade?
The world's largest carbon sink
What is the ocean?
Why aren't decomposers traditionally on energy pyramids?
What is they decompose all levels?
describe the flow of energy in an ecosystem
One-directional and non-recyclable, upward through trophic levels and getting smaller with each level
The role bacteria play in the nitrogen cycle
What is fixing nitrogen from the air into the soil?
