Honors Chapter 6: Ecosystem Balance Review

Consumers that actively hunt other living organisms

are called_________.

predators

This is why new species are able to form on islands

Large niche diversity, no competition, no

predators

This might happen after a forest fire

Secondary succession

The organism that is being eaten

prey

Give an example of a mutualistic relationship

Chance for a triple!!!!

What two organisms make up a lichen?

Fungi & Algae

Chance for a double!!

T/FPrey population follows predator

population in size

False

What two factors determine a terrestrial biome?

Temperature & Rainfall

Chance for a double!!

What is the most diverse terrestrial biome?

Tropical Rain Forest

A community that does not undergo further succession is

called

Climax Community

One organism benefits the other is harmed

Parasitism

Compare & contrast the desert & the tundra

Both receive little rainfall however desert is hot & the

tundra is cold

Bare Rock, Glaciers retreating

Primary succession

Describe the steps of primary succession

Bare rock, lichens, soil formation, grasses, shrubs,

seedlings, large mature trees.

Chance for a home run!!!!!!

Give an example of commensalism

Chance for a double!!

Why are there so many birds in an island community

B/C they can get there easier than other animals b/c of flight

T/FIf an ecosystem goes out of balance, it cannot adjust to regain the balanced state.

False

Give an example of a parasitic relationship

Chance for a double!!

75% of Earth’s biomass is contained in

forests

An increase in a predator population will directly result in

A decrease in the prey population

Chance for a home run!!!!!!

Describe the difference between predation & parasitism

When would you find populations of host organisms

parasitized?When they are overcrowded

Describe the Chaos theory

Chance for a triple!!

An organism that feeds on the body fluids or tissues of

another organism but does not kill it is called a

_________________.

Parasite

Name the three different types of forests

Deciduous

Coniferous

Rain

Which biome do you live in?

Deciduous Forest

What are two theories that explain how the dinosaurs became extinct?

Large comet or asteroid & Changing climate

Chance for a homerun!!!

Which stage of succession has a high evaporation rate?

Grass

Describe the process of aquatic succession

Chance for a triple!!

Which stage of succession is more biodiverse?

Forests

T/F Most communities never reach

a climax stage

TRUE

Any relationship in which two species live closely together &

at least one species is benefitting.

Symbiosis
