Biotic vs Abiotic
What is the definition of the term "biotic" relating to organisms in an ecosystem?
Anything living or once lived before
What is the role of producers in an ecosystem?
To produce energy for consumers, usually plants that provide energy from photosynthesis.
Which order of consumer eats primary consumers?
Secondary Consumers
True or False: The water, carbon, and nitrogen cycles are all abiotic.
True
The process of the ocean water becoming more acidic.
Ocean Acidification
What is the definition of the term "abiotic" relating to organisms in an ecosystem?
Anything non-living or has never lived.
What is the role of consumers in an ecosystem?
Organisms that hunt and scavenge in order to eat other organisms to get their source of food and energy.
What is the highest level of a food chain besides apex predators?
Tertiary Consumers
_____ is water that hits the ground and can infiltrate (soak) into the ground or flow over the ground in little streams back to bodies of water.
Runoff/Infiltration
What is Eutrophication?
The process of something getting too much energy.
Biotic or Abiotic: Dandelions
Biotic
What is another term used for producers?
Autotrophs
This consumer helps recycle the remaining nutrients from the dead bodies left by scavengers back into the soil for the producers to use again.
Decomposers
In this stage of the water cycle, water vapor cools and changes back into liquid droplets, forming clouds.
Condensation
What can cause Acidification?
Too much CO2 being pumped into the atmosphere. This causes the body of water to become more acidic!
True or False: The air, sun, and water are all biotic things.
False
What is another term used for consumers?
Heterotrophs
This consumer finds and eats the dead bodies of tertiary consumers once they have passed away, helping to clean up the ecosystem and stop the spread of disease.
Scavengers
This cycle is a process that describes the continuous movement of N2 through the Earth's atmosphere, soil, and living organisms.
Nitrogen Cycle
What process can happen when too much nitrogen enters the water?
Eutrophication
Which is BIOTIC?: Animals or Plants
Both
What type of consumer eats BOTH plants AND animals for its food?
Omnivore
What is the source of all energy in an ecosystem on land provided to function a food chain/web?
The Sun
This process in the carbon cycle involves the breakdown of organic matter by decomposers, releasing carbon dioxide back into the atmosphere.
Decomposition/Respiration
When farmers use too much ______, some of it gets washed out of their fields by the rain and runs off into the nearest bodies of water, causing eutrophication.
Fertilizer
