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

T/F Prey population follows predator population in size False

What two factors determine a terrestrial biome? Chance for a double!! What two factors determine a terrestrial biome? Temperature & Rainfall

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 Chance for a home run!!!!!! Describe the steps of primary succession Bare rock, lichens, soil formation, grasses, shrubs, seedlings, large mature trees.

Give an example of commensalism Chance for a double!! Give an example of commensalism

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/F If 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!! Give an example of a parasitic relationship

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

Describe the difference between predation & parasitism 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!! Describe the Chaos theory

An organism that feeds on the body fluids or tissues of another organism but does not kill it is called a _________________. Parasite

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
