Biology B7

the variety of living organisms

decaying flesh and tissue of dead animals

made up of the populations of different species living in a habitat

the negative interaction between two or more organisms which require the same limited resource

feed on other organisms for their energy. Can be primary, secondary or teriatry

orgaisms which feed on dead and decaying organisms. They break down on biomass and release nutrients into the soil.

the removal and destruction of trees in forest and woodland

the interaction between the living organisms and the different factors if the environment

the increase of the average global temperature

where a living organism lives

The interaction between two or more orgaisms , where it is mutually beneficial

the number of inividual organisms of a single species living in a habitat

organisms which kill for food

the animals which are eaten by the predators

convert the sun’s energy into useful compounds through photosynthesi. They are green plants or algae.

Organisms which feed on dead animals (carrion)

organisms of similar morphology which can interbreed to produce fertile offspring

Abiotic factors are the non- living factors of an environment e.g. moisture, light, temperature, CO (small 2), wind, O (small 2) or pH

the living factors of an environment e.g. predators, competition, pathogens, availability of food

They are specific features of an organism which enable them to survive in the conditions of their habitat

• structual • behavioural • functional

they are features of the organism’s body e.g. colour for camouflage

they are how the organism behaves e.g. migration to a warmer climate during colder seasons

they are the ways the physiological processes work in the organism e.g. lower metabolism during hibernation to preserve energy
