Energy Flow
Energy Flow
Energy Pyramids
Photosynthesis/ Cellular Respiration
Classification/ Characteristics
100
Described as a single pathway displaying the flow of energy and nutrients from organism to organism.
Food Chain
100
The ultimate source of energy for all food chains/ webs........
The sun
100
What is the second level in an energy pyramid?
Primary consumer
100
This chemical process is how producers/ plants produce energy and nutrients.
Photosynthesis
100
These 2 of the 3 domains are characterized as prokaryotes.
Bacteria and Archaea
200
The arrows in food chains/ webs represent.........
The energy/ nutrients being transferred
200
Described as multiple pathways displaying the flow of energy and nutrients from organism to organism.
Food Webs
200
How much energy do you need to multiply by to get to the next trophic level?
.10
200
This chemical process takes place in the absence of oxygen.
Anaerobic Respiration
200
Protists, Fungi, Plants, and Animals are all apart of this domain.
Eukarya
300
These organisms are able to make their own food. (2 answers)
Producers or Autotrophs
300
Is this environment best described as a:
A) Tropical food web
B) Arctic food web
C) Aquatic food web
C
300
What do the percentages represent in pyramids? What do trophic levels represent?
Energy transfers between levels
Each hierarchical level of organisms, like producers, consumers, etc
300
What do pyramids, webs, and chains show?
Energy transfers between organisms
300
There are how many taxonomic levels?
8
400
Which organism has the least amount of energy? The most?
Producers have the most, the highest level consumer (apex) has the least
400
Aside from metabolic processes, energy can be lost in the form of.........
Heat
400
List 3 examples of decomposers
Bacteria, fungi, mushrooms
400
How do autotrophic organisms get energy? What is another word for autotrophic organisms?
Producers; photosynthesis
400
These are the 2 different types of stimuli.......
Internal and External
500
Identify the error in this food web
The arrows are not pointing the right way
500
In an energy pyramid, each trophic level has this percentage of the previous level's energy........
10%
500
Why does the energy pyramid grow smaller as it reaches the top?
Each higher level in the pyramid gets smaller because only about 10% of the available energy transfers to the next level.
500
What is the difference between food webs and food chains and why are food webs more realistic than food chains?
A food web is a bunch of chains interlocked, and it shows the various paths an organism could take instead of just one
500
This is described as maintaining a stable environment.
Homeostasis
