Abiotic vs Biotic Factors
Non living factors in an ecosystem
Abiotic Factors
This animal relationship describes when two organisms are fighting over limited resources.
Competition
The close relationship between two or more organisms of different species.
Symbiosis
What is the difference between a food web and a food chain?
A food chain shows how energy is transferred through an entire ecosystem using many different organisms and arrows. A food chain shows one specific path in which the energy could flow in an ecosystem.
Who performs photosynthesis?
Plants/Producers
Living factors in an ecosystem
Biotic Factors
This animal relationship describes when one organism (predator) hunts, kills, and eats another organism (prey).
Predation
What are the three types of symbiosis?
Mutualism, Commensalism, Parasitism
What do the arrows represent in a food web/chain?
Energy transfer
Who performs cellular respiration?
All living things
True or False: When a biotic factor dies, it is now considered an abiotic factor.
False
True or False: All animals that live in the same ecosystem have to have some type of relationship with each other.
False
What is mutualism?
A symbiotic relationship where both organisms involved are benefiting
True or False: The arrows in a food chain point from eaten to eater.
True
Where does photosynthesis take place?
Where does cellular respiration take place?
Chloroplast
Mitochondria
What is made up of all the interactions among abiotic and biotic factors?
An ecosystem
Provide a real life example of competition
Ex. Lions and cheetahs fighting over the same food source
What is parasitism?
A symbiotic relationship where one organism is benefiting (parasite) and the other is being harmed (host).
List the trophic levels (in order) in a food web.
Producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer/apex predator, decomposer
What are the reactors and products of photosynthesis?
Reactors: Water, Carbon dioxide, light energy
Products: Oxygen, glucose
List 4 examples of both abiotic and biotic factors that can be found in an ecosystem.
Ex answer:
Biotic - trees, flowers, squirrel, fish
Abiotic - water, soil, rocks, air
Provide a real life example of predation
Ex. An owl hunts and eats a mouse
What is commensalism?
A symbiotic relationships where one organism is benefiting and the other is not being helped or harmed in any way.
What are the ways in which living organisms are able to obtain and transfer energy from one organism to another within and ecosystem?
Hint: there are 3
Photosynthesis, Cellular Respiration, Decomposition
What are the reactors and products of cellular respiration?
Reactors: Oxygen, glucose
Products: Water, carbon dioxide, heat energy
