---|---|---|---|---|---|
Community | All the populations in a defined area
🗑
|
||||
Ecosystem | A community plus all the non-living matter in the area, e.g a forest includes not only the inhabitants but also the non-living parts of the soil
🗑
|
||||
Heterotroph | Organism that obtains its energy by feeding on other organisms
🗑
|
||||
Consumer | Organism that feeds on other organisms or parts of other organisms which it kills in the process.
🗑
|
||||
Herbivore | Animal that feeds on plants
🗑
|
||||
Carnivore | Animal that feeds on other animals
🗑
|
||||
Omnivore | Animal that feeds on both plants and animals
🗑
|
||||
Parasite | Organism that feeds on another organism (the host) without killing it
🗑
|
||||
Decomposer | Organism that feeds on dead organic matter
🗑
|
||||
Energy and nutrient flow | The energy that drives an ecosystem is ultimately converted to heat which cannot be re-used and is radiated out into space. Energy flow through and ecosystem is thus linear. Matter on the other hand is recycled
🗑
|
||||
Food Chain | A series of organisms through which energy flows; first link is always a plant
🗑
|
||||
Grazing food chain | Food chain in which the first link is living plant matter and the second kink is a herbivore
🗑
|
||||
Detritus food chain | Food chain in which the first link is dead plant matter and the second link is a decomposer
🗑
|
||||
Food web | A system of interconnected food chains
🗑
|
||||
Trophic level | Position of an organism in a food chain; p;ants occupy the first trophic level, herbivores the second, ect
🗑
|
||||
Food pyrimid | A graphic representation of the structure of a food chain, depicted as a pyramid having a broad base formed by producers and tapering to a point formed by end consumers.
🗑
|
||||
Succession | Progressive change in the composition of a community over time, leading eventually to a stable climax community. Primary succession begins with initially hostile conditions that are gradually made more fertile as a result of colonisation in pioneer plants
🗑
|
||||
Stratification | Vertical layering of the vegetation in a forest into emergents, canopy, sub-canopy, shrub layer, ground layer
🗑
|
||||
Zonation | Change in the composition of a community along a physical environmental gradient, e.g up a rocky shore of up a mountain
🗑
|
||||
Habitat | The place where an organism lives
🗑
|
||||
Environment | The sum total of all the factors in the surroundings that influence an organism
🗑
|
||||
Niche | The way an organism makes its living, its role in the community
🗑
|
||||
Adaptation | Any inherited feature that increases the chances that an organism will survive and reproduce
🗑
|
||||
Physical environment | Includes factors such as temperature, light intensity, humidity, salinity, pH, wind, and waterflow
🗑
|
||||
Biotic environment | Includes factors such as food, organisms, competition, predation, paratism
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
