An organism that breaks down dead organisms and recycles their nutrients back into the environment.
What is a decomposer?
These organisms produce energy through the use of photosynthesis
What are autotrophs/producers?
A group of land and aquatic ecosystems with similar climates and organisms.
What is a biome?
The variety of life.
What is biodiversity?
The organism that kills or eats another organism.
What is a predator?
The consumer that receives the most energy from the producers.
What is the primary consumer/herbivore?
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?

The approximate amount of time for primary succession.
What is centuries to a millennia?
What is Secondary Succession?
This is a collection of interlocking food chains.
What is a food web?
The biome with the most rainfall which results in the highest amount of biodiversity.
What is the tropical rainforest?
First species to populate a new area.
What is a pioneer species?
3 Reactants=water, carbon dioxide, sunlight
2 Products=glucose, oxygen
A small habitat that is affected by different abiotic limiting factors than the surrounding ecosystem that results in higher biodiversity.
What is a microhabitat?
This is the name of a mature, stable, and very biodiverse ecosystem.
What is climax community?
This type of succession starts an ecosystem without soil.
What is a Primary Succession?
