A group of organisms of the same species that live in the same area
A group of organisms with similar characteristics that live in the same area and can interbreed
A group of populations of different species that live in the same area (biotic factors)
The study of organisms and their interactions with their ecosystem and with each other.
All the biotic and abiotic factors in a particular location
A collection of ecosystems that share a similar climate
living factor in an ecosystem. Ex: warbler, grasshopper, predation, etc..
non-living factor in an ecosystem. Ex: temperature, pH level, soil quality, precipitation, etc..
An organism that makes its own food
plants which 'produce' the energy for an ecosystem by trapping the sun's energy
the process of converting the suns energy into carbohydrates.
the process of converting sulfur into sugars, done by bacteria.
an organism which gets its energy from consuming other organisms
Same as a heterotroph
a consumer/heterotroph that eats meat
a consumer/heterotroph that eats plants
an organism that eats dead meat
an organism which eats both plants and animals
an organism which eats and breaks down dead organic matter (plants and animals)

Tiny microscopic plants that live in water
tiny little animals that live in the ocean and eat phytoplankton
primary producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer
Amount of organic mass at any given trophic level
process by which nitrogen moves from the soil, to plants, back to the soil, to the atmosphere, and back to the soil where it can once again be consumed by plants.
When bacteria convert atmospheric nitrogen into ammonia
process of converting ammonia into nitrates that can be taken up by plants and used to grow big and strong
process by which ammonia is converted into atmospheric nitrogen through dissolution and evaporation
day to day patterns of temperature and precipitation in a particular location
monthly or yearly general weather trends that exist in a particular location
When carbon dioxide builds up in the atmosphere and prevents some of the suns energy from escaping the atmosphere, therefore creating a 'greenhouse effect' and warming the planet slightly.
location where an animal lives (its address)
role an organism occupies within its ecosystem (job)
When one organism eats another
when one organism eats a plant
a long term relationship existing between two organisms
relationship in which both organism benefits
relationship in which one organism benefits and the other is harmed
relationship in which one organism benefits and the other is unaffected.
process after a volcanic eruption or fire where the ecosystem slowly comes back piece by piece in a particular order.
succession which starts from bare rock and takes longer (volcanic eruption)
succession which starts from empty soil and happens quicker (fire)
First species to return after a fire or volcanic eruption
The pinnacle or ending community that results from succession.
a biome where freshwater and saltwater meet.
When you leave your country and go somewhere else to a new counry
When you come from another country back to your own country.
Density Dependent Factors
factors which are affected by the population of organisms
Density Independent Factors
factors which are not affected by the population of organisms
relationship in which one organism is harmed and the other is unaffected
the ability to survive and reproduce
a non-native organism that tends to take over an ecosystem.
