Biology Flashcards
Carnivore
Animal that eats other animals
Consumer
Organism that relies on other organisms for its food.
Decomposers
Small organisms that break down dead and decay matter.
Detritivores
Organisms that consume detritus; that is decomposing plants and or animal parts or faeces.
Herbivore
Animal that only eats plants.
Producer
Organisms such as plants, that use photosynthesis to make their own food from the sun’s energy.
Omnivore
Animal that eats both plants and other animals.
Ingestion
Take (in foods), into our body.
Ecology
The study of environment.
Biotic Factors
Living Factors in the environment.
Examples: bacteria, worms, birds, plants, snakes etc.
Abiotic Factors
Non-living factors in the environment.
Examples: water, tempature, pH, salinity, light intensity
Organisms
A living thing.
Optimal range
Used to describe best conditions within the tolerance range in which the species are at their healthiest state.
Ecosystem
When abiotic factors and biotic factors are together.
Photosynthesis
Plants use the sun’s light and turn it into energy.
Community
All of the different populations living in the same place at the same time.
Introduced species
An introduced species is one that has been released into an ecosystem in which it does not occur naturally.
Steps of the water cycle
- Transpiration or Respiration or Evaporation
- Condensation
- Precipitation
- Run-off
Independent Variable
What we are changing to observe its effect on another variable.
Examples: Salinity level/amount of salinity
Aim
An aim is what the experiment is supposed to accomplish.
Example: To find the optimal range of salinity that coastal grass and inland grass can tolerate.
Hypothesis
A hypothesis is what you think is going to happen (a suggested explanation that is tested) in an experiment.
Example: If we increase the salinity level, the germination of the seeds will decrease.
Results
Results are the details or data that are recorded in an experiment after the testing.
Example: The inland seed could grow in water with no salt or 2 m/L in it. The coastal could only grow in water with a salinity level of 3 m/L
Conclusion
A conclusion is the ending statement in which you describe if your hypothesis was right or wrong and that sums up the experiment. And if it was wrong, you describe what actually happened. The conclusion of an experiment relates to the stated aim.
How was this Investigation made a fair test?
We made it a fair test because there were multiple controlled variables which will make it possible to measure the only dependent variable and to make only one independent variable.
Dependent Variable
A variable that is expected to change when the independent variable is changed. It is observed or measured during the experiment.
