Community
A group of populations living and interacting in the same area
Primary Consumer
An organism that eats producers
Mutualism
A symbiotic relationship between 2 or more organisms of different species where all benefit from the association
The water cycle transports nutrients within and ecosystem and even from one ecosystem to another
How does nitrogen get back into the atmosphere? What type of organisms do that?
Denitrifying bacteria convert nirates to atmospheric nitrogen through a process called denitrification.
Biosphere
The sum of all of Earth's ecosystems in land, water, or air
Rate at which producers in an ecosystem build biomass
A symbiotic relationship between two organisms of different species where one benefits and the other is neither harmed nor benefited
Commensalism
Name other ways that oxygen is removed from the air
Oxygen is also removed from the air by fire, ozone formation, and the rusting of metals and minerals.
Where is phosphorus found and how is it released?
Phosphorus is a mineral found in rocks and it is released through weathering and erosion. It then dissolves in water of streams and rivers to be used by bacteria and plants.
Consumers
Organisms that eat living producers and/or other consumers for food
Pyramid shaped diagrams that show the amount of energy or matter at each trophic level in an ecosystem. There are 3 types, energy pyramid, biomass pyramid, and pyramid of numbers.
Ecological Pyramid
Parasitism
A symbiotic relationship between 2 organisms of different species where one benefits and the other is harmed
Name the other ways that oxygen is replenished in the air
Oxygen is also restored by Ozone destruction and water vapor destruction
When fruits or vegetables are imported into the United States from a foreign country, they are always very closely inspected for insects, even though most insects are not really harmful. Why is the inspection done?
If an insect not native to the U.S. were carried into the country through foreign fruits and vegetables, it could ruin the balance of the U.S. ecosystem.
Biotic Factors
Any living part of an environment
Symbiosis
What are the main types of terrestrial biomes: (there are 8)
1. Tropical rainforests
2. Savannas
3. Chaparrals
4.Deserts
5. Temeperate grasslands
6. Temperate deciduous forests
7. Tundras
8. Tiagas
What is nitrogen fixation? What type of organisms perform it?
Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into nitrogen-containing molecules that are useful to most organisms in creation. Nitrogen-fixing bacteria perform it.
What are the main types of aquatic biomes? (there are 6)
1.Marine oceans
2.Marine coral reefs
3.Marine estuaries
4.Standing freshwater(lakes and ponds)
5.Running freshwater (river and streams)
6.Freshwater wetlands (swamps, marshes, and bogs
Decomposers
Organisms that break down the dead remains of other organisms
Habitat
The specific environment of an organism both biotic and abiotic
Oxygen is take from the _____ principally by respiration and is _______principally by________
AIR, RESTORED, PHOTOSYNTHESIS
Carbon dioxide leaves the air by photosynthesis and by dissolving in the ocean
