| ecology | ecology is the study of how organisms interact with each other and with their non-living surroundings form an environement that is different from others near by
🗑
|

| ecosystem | a system where organisms interact with their physical surrondings to form an environment that is different from others nearby.
🗑
|
||||
| ecothermic | animals (eg. lizards) that obatin body heat from outside their body
🗑
|
||||
| endothermic | animals (eg. tiger) that can generate body heat internally.
🗑
|
||||
| environment | all the factors in an organism's surronding that affect it's survival
🗑
|
||||
| adaptions | any feature that assists an organism to survive and reproduce in it's environment.
🗑
|
||||
| adaptions 2 | any feature that assists an organism to survive and reproduce in it's environment. adaptions are classified as structural (eg. bats wings), behavioural (eg. nocturnal animals) or fuctional (how a piece of the body works).
🗑
|

| sustainability | is an ecosystem that has the ability to maintain suitable living conditions for the community.
🗑
|
||||
| biodiverty | a range of different species living in a community
🗑
|
||||
| commensalism | relatioship where one organism benefits and another organism is unharmed (eg. whale tail and barnacles)
🗑
|
||||
| interdependance | realtionship between organisms, where each other affects the other's survival (eg. predator and prey)
🗑
|

🗑
|
||||
| decomposers | decomposers are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.
🗑
|
||||
| food web | a system of interlocking and interdependent food chains.
🗑
|
||||
| food chain | A food chain is a network of links in a food web starting from producer organisms and ending at predator species, detritivores, or decomposer species.
🗑

| ecosystem to sustain itself | . substance necesaary for it's survival & growth (eg. water or nitrogen)
. input of energy (eg, sunlight)
. wide range o species living there - biodiverty
