Cycles
Details where water comes from and where it goes
What is the water cycle?
Organisms that break down the dead remains of other organisms
What is a decomposer?
A relationship between species in which one organism eats another
What is predation?
The biome with permanently frozen soil that does not allow for the growth of large plants
What is the tundra?
When organisms move out of an area
What is emigration?
The principal means by which oxygen is taken from the air
What is respiration?
Shows the energy transfer as a predator consumes its prey
What is a food chain?
A symbiotic relationship between two or more organisms of different species where all benefit from the association
What is mutualism?
The biome usually located near the equator and includes high rainfall, dense vegetation, and poor soil.
What is the tropical rain forest?
The number of individuals or a single species per unit area
What is population density?
Evaporation of water from the leaves of plants
What is transpiration?
What is a tertiary consumer?
What is mutualism, parasitism, and commensalism?
A type of grassland biome that experiences rainy seasons and long periods of drought
When succession ends the resulting community is similar to the one before the disturbance and reaches homeostasis or stability
What is a climax community?
The gas responsible for the greenhouse affect when released into the atmosphere in large quantities
What is Carbon Dioxide?
Each step or pathway of food transfer from one level to another in a food chain or food web
What is a trophic level?
A relationship between organisms for a limited supply of at least one resource
What is competition?
The biome usually dominated with tree species that shed their leaves in winter months
What is temperate deciduous?
The first organisms in the process of ecological succession
What are pioneer species or pioneer organisms?
The process by which certain gases trap heat that would otherwise escape the earth and radiate into space
What is the greenhouse effect?
Illustrates the biomass in each trophic level of an ecosystem
What is a biomass pyramid?
Barnacles on a Humpback Whale
What is an example of commensalism?
The biome dominated by conifer trees and short summers
What is tiagas?
A limiting factor that depends on population size, such as predation, competition, parasitism, and disease
What is a density-dependent limiting factor?
