Limiting Factors 

100

Limiting factors can be abiotic or biotic. 

True or False

TRUE

The number of births per 1,000 individuals for a given time period. 

Birth Rate 

100

The parts of the land, sea and atmosphere in which organisms are able to live. 

Biosphere 

100

a relationship in which two different organisms live in close association with each other.

Symbiosis

200

The largest population that an area can support. 

Carrying Capacity

200

All the different populations that live together in a particular area.

Community 

200

relationship where both organisms benefit. 

Mutualism

300

The number of individuals in an area of a specific size 

Population Density

Double Jeopardy

If you get this correct you receive double the points! 

Name the three types of Symbiotic relationships and the difference between them .

Mutualism= both benefit

Commensalism= one benefits and other is unaffected. 

Parasitism= one benefits and the other is harmed.

400

The number of deaths per 1,000 individuals for a given time period. 

Death Rate 
400

DOUBLE Jeopardy! 

If you get this question correct, your team gets double the points! 

What is the difference between density-dependent factors and density-independent factors?

Density-dependent: limiting factors that influence a population's birth and death rates when the population becomes too dense. (Starvation, lack of resources, spread of disease, predator/prey, competition, etc.) 

Density-Independent: limiting factors that influence a population’s birth or death rates, regardless of the population density.  (Temperature, natural disasters, level of oxygen in the atmosphere, etc.) 

400

Give one example as to why an animal might Emigrate from a habitat.

Lack of resources

Too much competition

Disease

ETC..

400

All the members of one species living in the same area.

Population 

400

Some shrimp and crab live and capture food from within the tentacles of giant anemones.

Commensalism

500

Moving into a population 

Immigration

Why are limiting factors important in ecology?

They keep the ecosystem balanced. 

500

In terms of populations in an ecosystem, what does ZPG stand for?

Zero Population Growth 
500

The community of organisms interact with each other and their environment.

Ecosystem 

500

The siboglinid tube worm, found at deep-sea hydrothermal vents and cold seeps, has no digestive tract. It relies on symbiotic bacteria that live in the tube worm’s tissues. The bacteria oxidize hydrogen sulfide or methane for the worm.
