This type of succession occurs when there are no traces of the original community remaining, including vegetation and soil. 


Primary Succession

100

What is evolution? 

The gradual change of an organism over time.

In Madagascar, several species of lemur eat bamboo, but each species specializes in one part of the bamboo. One species eats the leaves and the other eats the stalk. This is an example of...

Resource Partitioning

What percent of energy transferred between trophic levels is lost?

90%

When an environment changes too quickly for an organism to adapt __?__ will occur. 

Extinction

200

This type of succession occurs when a disturbance dramatically alters a community, but does not completely destroy it.


Secondary Succession

Pronghorn are a species of very fast hooved mammal in western North America. Currently, no predator can catch them. During the ice age, cheetahs occupied North America. How did the pronghorn become so fast?

Coevolution 

200

This describes an organism’s use of resources and functional role in a community.


Niche

Primary Succession

How many known mass extinction events have there been?

5

300

A long-lasting and physically close relationship between species in which at least one species benefits.

Symbiosis 

300

Explain why a food web is a better representation of energy flow compared to a food chain. 

A food chain is a linear series of feeding relationships. While a food web shows the overlapping and interconnected food chains present in a community.

Secondary Succession

Describe allopatric speciation. 

The creation of a new species after the population has been isolated due to geographical barriers.

A beehive depends on pollen from flowers, flowers depend on bees to pollinate them, humans tend to hives for honey. Describe the relationship. 

Mutualism

400

In a food web/food chain, what do the arrows represent? 

Energy Flow

400

Nonnative organisms that spread widely in a community due to a lack of limiting factors such as predators, parasites, or competitors.

Invasive Species

500

The first to colonize an area (ex. lichens, moss).


Pioneer Species

500

State the 3 conditions of natural selection. 

1. More offspring are produced than can survive.

2. Individuals vary in heritable characteristics.

3. Individuals vary in fitness/reproductive success. 

500

A relationship in which one species benefits while the other is unaffected.


Commensalism
500

In a food web that consists of grass, mice, deer, coyotes and hawks - which species has the greatest biomass?

Grass

500

Species that have strong and/or wide-reaching effects on a community.
