What is the most important abiotic factor on Earth?
Water
100
What is a biotic factor?
A biotic thing is a living thing
100
Interactions among organisms in an ecosystem.
What is ecology?
100
What is a similarity between abiotic and biotic factors?
They are both on Earth! They are both in every ecosystem.
100
What is an organism?
An organism is a living thing that lives as a part of the food chain.
200

Name 5 abiotic factor

I will judge...

200
What is an example of a biotic factor?
Anything that is living...
200
What is the lowest level of ecology? And what does it study?
Organismal (individual) ecology. Studies 1 organism's relationship with it's environment.
200
Difference between autotrophs and heterotrophs.
What is autotrophs make their own food, and heterotrophs get it from other sources?
200
All energy on Earth must go through this group before any other. (Energy comes from sunlight or chemical energy)
Autotrophs/Primary Producers.
300
What is an abiotic factor?
A non-living part of an ecosystem.
300
What is a biotic factor's relationship to a abiotic factor?
A biotic thing uses abiotic factors to enhance its life
300
Biome ecology is studied where?
Study of organisms in a group of ecosystems that share a SIMILAR CLIMATE.
300
Defining consumer groups is easy for every organism? Why or why not?
Not always easy. Some organisms can fit into multiple groups.
300
All energy in an ecosystem is converted back to usable energy for primary producers to use by which group?
Detritivores.
400
What is an abiotic factor's relationship to a biotic thing?
An abiotic thing is used to enhance the life of a biotic thing, EX: water is used by biotic things
400
What do all biotic things need?
Oxygen, water, food, living space, and stable internal conditions. FOOD-WATER-SHELTER
400
Name the levels of ecology from lowest to most complex.
Organismal, Population, Community, Ecosystem, Biome, Biosphere.
400
What is the difference between a detritivore and a decomposer?
Detritivores feed on decomposer's waste. Detritivores are final stage in energy cycle, where there waste supplies producers with nutrients.
400

Explain how energy cycles through an ecosystem. Where does it start? Where all does it go? State the steps in the cycle...

Sunlight or chemical energy that is converted to usable energy by autotrophs ->  

Consumers use energy gained from autotrophs -> Decomposers chemically break down dead/organic matter, producing detritus    -> 

 Finally detritivores digest waste from decomposers giving nutrients back to primary producers.

Is an organism an abiotic factor?
NOPE! ;)
500
What is an ecosystem?
All living communities and their non-living components in a DEFINED area.
500
Greek word meaning "house." (Root word of ecology)
What is Oikos? (root word in ECOlogy) Study of nature's "houses," and organisms living in those "houses."
500
Difference between ecosystem ecology and community ecology?
Number of species being studied.
500
How are consumers classified?
By the ways in which they acquire energy.
