|
Predator |
hunts animals for food example: lion |
|
prey |
hunted for food example: zebra |
|
decomposer |
gets food from dead organisms or the waste of organisms example: mushroom (fungus) |
|

receives benefits from the organism that it lives in, with, or on example: flea, tick, leech, nematode, parasitic wasp |
|
host |

|
photosynthesis |
plant's leaves and stems make sugars and release oxygen by using the Sun's energy, carbon dioxide and water |
|
Ecosystem |
mix of all biotic (living) and abiotic (non-living) things, conditions, and interactions in an area; organisms and populations depend on and may compete for resources and are affected by other factors (like temperature and humidity) within the ecosystem |
|
Run-off |
rain water containing soil contaminated with fertilizers reachers the ocean; the build up of soil destroys coral reef habitats; the nutrients in the runoff affect oxygen levels and change the ocean's ecosystem, resulting in fish deaths |
|
artificial reefs |
sunken human-created structures (like old trucks, boats, or bridges) provide a home for marine life like corals and sponges |
|
Overfishing |
humans remove fish until that species' population is greatly reduced or even eliminated |
|
Biotic factors |
LIVING factors in the environment plants, animals, fungi |
|
Abiotic factors |
NON LIVING factors in the environment soil, sun, water |
|

|
Freshwater Ecosystem |
