200
This biome is characterized by having very few trees and a layer of permanently frozen soil (permafrost)
What is the Tundra

What is a limiting factor
300
Individual organisms of a single species that share the same geographic location at the same time
What is a population
300
A model representing the many interconnected food chains and pathways in which energy flows through a group of organisms
What is a food web
300
This biome is characterized by scattered trees and grasses, and by less precipitation than other tropical areas
What is a Tropical savanna
300
The process of capturing and converting nitrogen into a form which plants can use
What is nitrogen fixation
300
The variety of life in an area that is determined by the number of different species in that area
What is biodiversity
400
A large group of ecosystems that share the same climate and have similar types of communities
What is a biome
400
Each step in a food chain or food web
What is a trophic level
400
This biome is composed mostly of deciduous trees…trees that shed their leaves in the autumn
What is a Temperate forest
400
Plants release carbon into the atmosphere through this process
What is photosynthesis
400
The increase in concentration of a toxic substance in organisms as tropic levels increase in a food chain or food web
What is biological magnification
500
When one organism benefits and the other organism is neither helped nor harmed
What is commensalism
500
The total mass of living matter at each trophic level
What is biomass
500
This biome is located just south of the Tundra and is a broad band of dense evergreen forest extending across North America, Europe and Asia
