100
the study of organisms in their environment
What is Ecology
100
An organism that eats other organisms due to the fact it can't make its own food
What is a heterotroph
100
This organism only eats animals
What is a carnivore
100
This organism eats both plants and animals
What is an omnivore
100
This is the main source of energy for all life
What is the sun
200
The six levels of Ecology
What are 1: individual 2:population 3: community 4: biom 5: biosphere
200
The two ways autotrophs make their food
What are 1: photosynthesis: power throw sun light 2: chemosynthesis: power through chemical reactions
200
This is the process that makes N2 a usable source
What is Nitrogen Fixation
200
This cycle is associated with evaporation
What is the water cycle
200
Area where a particular animal lives
What is a habitat
300
The simplest grouping of more than one kind of organism
What is a community
300
The name to describe all living things on the planet
What is a biosphere
300
This organism fixes nitrogen
What is bacteria
300
The max number of organisms an ecosystem can hold
What is the carrying capacity
300
A relationship between two organisms where one benfits at the others expense
What is paracitism
400
Things in the environment that causes a population to decrease
What are limiting factors
400
This organism only eats plants
What is a herbivore
400
This cycle is associated with ammonia
What is the nitrogen cycle
400
A relationship between two organisms where both benefit
What is mutualism
400
A relationship between two organisms where one organism benefits and the other is unaffected
What is commensalism
500
Type of organism at the lowest point on the food chain
What are producers
500
3 examples of biogeochemical cycles
What are the nitrogen, carbon, and water cycle
500
This cycle is associated with denitrification
What is the nitrogen cycle
500
These two reasons cause only 10% of energy to be passed on to the trophic level
What are 1) some of it used by the organism 2) some is given off as heat
500
This describes a Density-Dependent factor
What is when an population can be affceted by the number of organisms in the population
