|
Producers |
Carry out photosynthesis (plants, algae). Turn sunlight into useful energy. They are Autotrophs: make their own food. |
|
|
Consumers |
Eat other organisms. Can’t produce their own food(heterotrophs). |
|
|
Herbivore |
only plants. |
|
|
Omnivore |
plants and meat. |
|
|
Carnivore |
only meat. |
|
|
Consumers |
Animals that eat other animals =predators. Animals that are hunted = prey. |
|
|
Scavengers |
Eat remains of dead animals. |
|
|
Detrivores |
Feed on organic matter (e.g. remains ofdead organisms, waste). |
|
|
Decomposers |
Break down matter and release nutrientsback into ecosystem (recycles them!). |
|
|
Food Chain |
Shows feeding relationships. |
|
|
Trophic Levels |
Level in an ecosystem depending on feeding position. |
|
|
Trophic Levels - 1st trophic level |
producers. |
|
|
Trophic Levels - 2nd |
primary consumers. |
|
|
Trophic Levels - 3 rd |
secondary consumers. |
|
|
Trophic Levels - 4th |
tertiary consumers. |
|
|
Food Web |
Many consumers eat different foods. Better modelled by a food web |
|
|
Energy |
Only 10% of energy from food is stored in the body andcan be passed on to another animal! 30% usedfor bodyprocesses. 60%passed outin wastes. |
|
|
Energy Pyramids |
Show amount of available energy. Shows the importance of producers (lotsof energy!). Because of less energy left at each level, thereare also less individuals. |
