BIOMES
100
Feeding levels in a food chain.
What are Trophic levels?
100
Things that affect the size of a population
Limiting factors?
100
The final organisms in a stable community
What is a Climax community?
100
Difference between a food chain and a food web
Many different food chains in an ecosystem create a food web.
100
3 Causes for differences in biomes
Climate, altitude, latitude
200
A niche
Strategies and adaptations an organisms uses to live grow and survive?
200
Amount of organism the land can hold sustainably.
What is carrying capacity?
200
Organisms that first appear on new land
What are pioneer species?
200
Nitrogen fixing bacteria does what?
Brings Nitrogen into the soil
200
Biomes of the water are called this and give 2 types
Aquatic? Freshwater/ Marine
300
Grass --> Rabbit --> Snake --> Hawk. Which organism(s) is a herbivore
Rabbit
300
Exponential growth and an example
Unrestricted growth of a population like humans
300
When a forest burns down and it recovers quickly is a type of this
Secondary succession
300
When trees are cut down and the home of different organisms is removed.
Habitat Loss -
300
Area of the ocean where no light penetrates?
Aphotic Zone
400
Corn--> Mouse --> Cat Which organisms population will have the greatest biomass in an ecosystem
The corn.(producers)
400
Factors like predators, food supply, disease and competition that restrict growth
density dependent factors
400
When a land was primarily rock and over time changes in the populations of the area create soil and a climax community of organisms
PRIMARY SUCCESSION
400
Diagram that shows how many of a feeding level are present in the ecosystem
Pyramid of numbers
400
An Estuary
Area of water where saltwater meets freshwater
500
GROUP : Organisms that are eaten by a predator
What is prey
500
Density Independent factors and an example
things that restrict growth like climate, natural disasters, and pollution
500
Lichens and mosses are usually this
Pioneer species
500
The coldest biomes on earth
Arctic Tundra and Taiga
500
logistical growth of a populate is caused by these
What are limiting factors?
