100

An organism that breaks down dead organisms and recycles their nutrients back into the environment.

What is a decomposer?

100

These organisms produce energy through the use of photosynthesis

What are autotrophs/producers?

100

A group of land and aquatic ecosystems with similar climates and organisms.

What is a biome?

100

The variety of life. 

What is biodiversity?

100

The organism that kills or eats another organism.

What is a predator?

200
The community of organisms that live in a particular area, along with their nonliving surroundings. This includes abiotic and biotic factors.
What is an ecosystem?
200

The consumer that receives the most energy from the producers.

What is the primary consumer/herbivore?

200

The biome you would be in if you were standing on a bitterly cold, dry plain with only a few, short plants scattered around. (Hint: The soil is permanently frozen so no trees grow here.)

What is the tundra?

200

A species that invades an area and conquers it. Examples: Burmese python, Kudzu

What is an invasive species?

200

The approximate amount of time for primary succession.

What is centuries to a millennia?

300
When an ecosystem starts to rebuild but it starts with soil.

What is Secondary Succession?

300

This is a collection of interlocking food chains. 

What is a food web?

300

The biome with the most rainfall which results in the highest amount of biodiversity. 

What is the tropical rainforest?

300

First species to populate a new area. 

What is a pioneer species?

300
A carnivore that feeds on the bodies of dead organisms.
What is a scavenger?
400
The 3 reactants and the 2 products of photosynthesis.

3 Reactants=water, carbon dioxide, sunlight

2 Products=glucose, oxygen

400
This is a way to show how energy in a food web is allocated. Usually there is a large base and a pointed top.
What is an energy pyramid?
400

A small habitat that is affected by different abiotic limiting factors than the surrounding ecosystem that results in higher biodiversity. 

What is a microhabitat?

400

This is the name of a mature, stable, and very biodiverse ecosystem.

What is climax community?

400

This type of succession starts an ecosystem without soil.

What is a Primary Succession?

500
A series of events in which one organism eats another and obtains energy. Usually written on one line.
What is a food chain?
500
What is the percentage of energy LOST as it moves from producer to primary consumer to secondary consumer?
What is 90%?
500

List 5 of the 8 major biomes we covered during this unit.

What are the rain forest, desert, grassland, deciduous forest, boreal forest, tundra, marine, or freshwater?

500

List several limiting factors that result in high biodiversity. 

Students answers may vary:

water, temperature, competition, predators, access to resources

500

Name the 5 types of heterotrophs.

What are Scavenger, carnivore, herbivore, omnivore, and decomposer?
