Vocab
Potpourri
100
The broadest level of organization; includes the Earth's crust and its atmosphere
What is the Biosphere?
100
A producer is this, meaning it makes its own food
autotroph
100
When one organism captures, kills, and eats another
What is PREDATION (or predator/prey relationship)?
100
This type of consumer simply feeds on dead organisms, while decomposers break down decaying matter.
Scavenger
100
This type of organism is able to make its own food
What is a PRODUCER (or AUTOTROPHIC)?
200
includes all of the organisms and the abiotic physical environment found in a particular place
What is an ECOSYSTEM?
200
In the pyramid of energy which area of the pyramid has the LEAST amount of energy?
The very top
200
Mutualism, commensalism, and parasitism are examples of this.
Symbiosis.
200
This is a step in a food chain that shows energy passage.
Trophic Level
200
This kind of organism must get food/energy from consuming another
What is a CONSUMER (or HETEROTROPHIC)?
300
includes all the interacting populations LIVING in an area (doesn't include non-living)
What is a COMMUNITY?
300
Between producer and consumer, a human is this
What is a CONSUMER?
300
When one organism feeds on another (latter known as the host)
What is PARASITISM?
300
Network of interconnected food chains. This is also a more realistic model of what occurs in nature.
Food Web
300
A cheetah and a gazelle are an example of this type of relationship
What is PREDATION (or predator/prey)?
400
All of the members of ONE SPECIES that live in one place at one time
What is a POPULATION?
400
A consumer is this, meaning it has to get its energy from other organisms
hetertroph
400
A relationship between organisms in which each benefits (like a bee and a flower)
What is MUTUALISM?
400
In a pond ecosystem, ducks, mosquitos, plants, and frogs are all __________ factors.
biotic
400
LIVING factors that are a part of an ecosystem
What are BIOTIC factors?
500
Includes the one living thing; the narrowest level of organization
What is an ORGANISM?
500
What is the difference between a food web and food chain?
Food webs are composed of many interconnected food chains. Food chains only list one organism at each trophic level. Also, food webs are a more realistic picture of what happens in nature.
500
A relationship in which one species benefits and the other is not affected (e.g. birds and buffalo in Tanzania)
What is COMMENSALISM?
500
Before plants can use many organic materials,these materials must be broken down by ____________
Decomposers
500
Pollution, conservation by humans, amount of rainfall
What is a examples of ABIOTIC factors?
