the systematic study of the structure and behaviour of the physical world by watching, measuring and performing experiments
living environment e.g. fauna and flora
non-living environment e.g. rocks
a group of organisms that can interbreed and produce a fertile offspring
the environment in which a species normally lives or the locations of a living organism
a group of organisms of the same species who live in the same area at the same time
a group of populations living and interacting with each other in an area
a community and its abiotic factors
the study of relationships between living organisms and the environment
an organism that synthesises its organic molecules from simple inorganic substances(plant)
an organism that obatins organic molecules from other organisms (animal)
an organism that ingests other organic matter that is living or recently killed
an organism that makes food using inorganic material(sunlight).plant-photosynthesis
an organism that ingests non-living oranic matter e.g. snails and worms
an organism that lives in or on non-living organic matter, secreting digestive enzymes into it and absorbing the products of digestion
the position an organism occupies in a food chain-what it eats and what eats it
a series of related food chains. Organisms are related by predator-prey and consumer-resource interactions
organisms, typically microorganisms, that feed on dead plant and animal matter, causing the matter to be recycled by other living things
an organism's habitat and function in the food web
a contest between individuals, groups, nations, animals etc. for territory, a niche or a location of resources
the consumption of herbacecous vegetation
relationship where one animal(predator) catches and kills another(prey) to eat
relationship where one organism(parasite) lives in or on another(host) for most of its lifecycle deriving its nutrients from the host
Mutualism and commensalism
a relationship in which both organisms benefit from the association(opp of symbiosis)
a relationship where not all organisms benefit from the association(opp of mutualism)
