Term | Definition |
---|---|
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) |
parasitism | relationsip where one organism lives on or in another organism and harms it. eg. the parasite lives on the host & feeds off it haring it, (eg. caterpillar and wasp larvae or parasite). |
biotic factors | any living factor of the environment (eg. |
abiotic factors | any non-living factor of the environment (eg. light, water, fire, soil, oxgyen, temperature). |
competition | when oraganisms both try to obtain the same resorce - food or shelter etc (eg. chicks competing for food from mother). |
predation | when one organism (predator) kills and eats another organism (prey). (eg. lion killing and eating a zebra). |
mutualism | a realtionship where two organisms live closely together and both benefit (eg. birds and zebra; the bird get food and the beasts get pest control). |
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 |
