Relationships
In this relationship, both organisms benefit.
Mutualism
Overlapping trophic levels.
Food web
Has very low precipitation and plants and animals must adapt to living with little water or store the water.
Desert
Make their own food (give two names)
Producers and autotrophs
Total amount of living matter that the ecosystem can support
Biomass
In this relationship, one organism benefits and one is not affected.
Commensalism
grass --- zebra----lion ---- bacteria
(which way do the arrows go?)
to the right (to whoever gets the energy)
Oak, birches, and maple trees grow in this biome. Moderate temperatures and rainfall.
Deciduous forest
Eat producers
consumers
A group of deer would be called this
Fighting over a mate is an example of this.
Competition
This group is located on the bottom of the pyramid.
Primary level/Autotrophs/Producers
Permanently frozen ground with little vegetation. Long winters, short summers. Grizzly bears and caribou.
Tundra
Terms used for animals that eat other animals.
carnivores/secondary consumer
all the different plants and animals in a particular ecosystem are called this
community
A vine growing on a tree and harming the tree is an example of this type of relationship.
Parasitic
These are the 3 major elements of food chains.
producers, consumers, decomposers
Trees like hemlock, redwood, and fir. Moderate rainfall, cooler temperatures. Wolverines, elk and moose live here.
coniferous forest
Breaks down dead plants and animals
decomposer
The ecological layers in a biome due to elevation or depth of water.
veritcal zonation
Type of biological interaction where one species causes harm to another organism without any cost or benefits to itself. (like elephants stepping on ants)
Amensalim
The purpose is to show the flow of energy.
Food chain.
Warm dry summers, cool wet winters. Smallest biome, but plant life very diverse.
Chaparral
An organism's role in the habitat/ecosystem.
Niche
List 4 abiotic factors in the rainforest.
Air, water, sun, rocks
