| Term | Definition |
|---|---|
| Habitat | The place where an organism (living thing) lives |
| Adaptations | Characteristics that help and organism to survive and reproduce |
| Eukaryotes | Mostly multicellular, contain nucleus, contain membrane bound organelles. E.g. plant cells |
| Prokaryotes | No nucleus, no membrane bound organelles, mostly unicellular. E.g. bacteria |
| Protists | Group in which organisms end up in if they are not prokaryotes, fungi, plants or animals. Protists are extremely diverse. Eukaryotes, mostly unicellular, some asexual and some sexual, autotrophs and heterotrophs |
| Plantae (plants) | Autotrophs. Have chlorophyll in chloroplasts. Have a cell wall. asexually/sexually |
| Fungi | Most are eukaryotic. Single celled fungi are yeasts. Reproduce with spores. Cell walls made of chitin. Decompose dead materials. Heterotrophs. Excrete powerful enzymes. Lysotrophs - decomposers |
| Animalia (animals) | |
| Archaea | |
| Bacteria | |
| Heterotrophs | |
| Chemotrophs | |
| Invertebrates | |
| Colonial | |
| Solitary | |

| Symbiosis | |
| Mutualism | Positive for both organisms (+ +) |
| Commensalism | Positive for only one organism and no effect on the other (+ 0) |
| Parasitism | Positive for only one organism that lives and shelters on the other organism. The relationship is detrimental to the other organisms (+ -) |
| Predators | Eat other organisms (prey) |
| Prey | The organism that is eaten by the predator |
| Competitors | Two organisms that eat the same food/use the same recourses and live in the same habitat |
| Food chain | sun - grass - grass hopper - kookaburra - bacteria |
| Producers | Producing their own food (aka autotrophs) |
| Consumers |
