Cycles
The process by which plants remove Carbon Dioxide from the atmosphere in order to create energy.
What is the photosynthesis?
Organisms that break down the dead remains of other organisms
What is a decomposer?
A close relationship between rwo or more species where at least one benefits.
What is Symbiosis?
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 by humans and other breathing organisms.
What is respiration?
A series of steps in which organisms transfer energy by eating and being eaten.
What is a food chain? BONUS OP!! Draw a food chain with 4 consumers.
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?
This process describes the evaporation of water from the leaves of plants.
What is transpiration?
What is a tertiary consumer?
A relationship between 2 or more organisms where one benefits and one is harmed.
What is parasitism?
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?
These organisms produce their own food.
What are producers?
A relationship between organisms for a limited supply of at least one resource
What is competition? BONUS OP!
Which is an example of COMPETITION?
A zebra and a lion OR a rabbit and a deer?
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 bacteria convert nitrogen in the air into useful organic nitrogen-based molecules.
What is nitrogen fixation or nitrogen fixing?
This Diagram illustrates the amount of energy or matter (aka biomass) in each trophic level of an ecosystem.
What is a biomass pyramid? OR What is an ecological pyramid? BONUS OP!
Draw an ecological pyramid with 4 levels where each level half half the biomass of the level above it.
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?
BONUS OP! If Predators are a density-dependent limiting factor . . . What is an example of a density- independent limiting factor?
