The smallest unit of an ecosystem (based on Ecological Organization)
What is Organism?
A diagram in a series showing the transfer of energy from one organism to the next in an ecosystem.
For example: algae is eaten by snails/ ducks eat snails/ foxes eat ducks
What is a food chain?
The lowest level of an energy pyramid is occupied by these.
What are producers?
A system of interconnected and interdependent food chains.
What is a food web?
Close relationship, involving energy, between two different organisms over a long period of time
What is symbiosis?
An organism that gets energy by eating other organisms.
What is a consumer?
Group of animals of the same species within a given area
What is a Population?
Arrows in a food chain show that this is being transferred.
What is energy?
Organisms referred to as primary consumers or herbivores occupy this level of an energy pyramid.
What is the second level?
The organisms responsible for creating energy within a food web.
What are producers?
In this symbiotic relationship between 2 organisms, both organisms benefit.
What is mutualism?
A living factor of an ecosystem.
What is a biotic factor?
Multiple populations of organisms within a given area.
What is a Community?
This should normally be written first in a food chain.
What is the sun?
These organisms occupy the third level of an energy pyramid.
What are secondary consumers or carnivores?
Organisms in food webs that consume plants and animals.
What are omnivores?
In this symbiotic relationship between 2 organisms, one organism benefits and one neither benefits nor is harmed.
What is commensalism?
Green algae in a farmer's pond is an example of this.
What is a producer?
All the organisms and the abiotic factors they depend on for survival within a given area.
What is an Ecosystem?
This is the first organism in a food chain.
What is a producer?
Lions, eagles, killer whales, and Great White sharks would occupy this level of an energy pyramid.
What is tertiary consumer or fourth level?
Organism missing from this food web.
What is a decomposer?
In this symbiotic relationship between 2 organisms, one organism benefits and one organism is harmed.
What is parasitism?
In this ecosystem, the relationship between the fox and the rabbit.
sun--->clover--->rabbit--->fox
What is predator-prey?
All the areas of the Earth capable of supporting life.
What is the biosphere?
This SHOULD be the last organism in a food chain.
What is a decomposer?
There are 40,000 kg of energy at the base the pyramid. This is the amount the secondary consumers will receive.
What is 400 kg?
This organism has 2 roles in the food web.
What is the Blue Jay?
Primary consumer (seeds/nuts)
Secondary consumer grasshopper
In this relationship, 2 different organisms of the species compete for the same resource in an ecosystem.
What is intra-specific competition?
In this ecosystem, the relationship between the fox and the hawk.
sun--->wildflowers--->rabbit----> fox
---->hawk
What is inter-specific competition?
