Ecology Flashcards
(41 cards)
Abiotic factors
Non-living factors of the environment
Biotic factors
Living factors of the environment
Population
All the organisms of one species living in a habitat
Habitat
The place where an organism lives
Community
The population of different species living in a habitat
Ecosystem
The interaction of a community of living organisms(biotic)with the non-living(abiotic)parts of the environment
Plants
Need light and space as well as water and mineral(ions) nutrients from the soil
Animals
Need space(territory),food,water and mates
Competition
Organism compete with other species or same species for the same reasons.
Interdependence
Each species depending on other species for food,shelter and pollination
Adaptations
Adaptations allows organism to survive in various different ecosystems
Behavioural
Behavioural some organism differentiate with how they behave like they move to a certain place during winter and summer time
Artic fox
Has white fur to be camouflaged against the snow.
Functional
Desert animals conserve water by producing very little swaet and small amounts of concentrated urine.
Bears Functionality
Hibernate during the winter lower their metabolism which conserves their energy.
Food chains
Food chains always start with an producer eg dandelions.
Producers
Producers are usually green plants or algae
Energy
Energy is transferred through living organisms in an ecosystem when organisms eat other organisms.
Producers 2
Producers make (produce) their own food using energy from the sun.
Food Chain 2
Producers are eaten by primary consumers. Primary consumers are then eaten by secondary consumers and secondary consumers are eaten by tertiary consumers.
Eg
Producer 5000 dandelions feed 100 rabbits primary consumer which feed 1 fox secondary consumer.
Carbon cycle
The constant cycling of carbon is called the carbon cycle.
Environmental change
The distribution of bird species in Germany changing as rise in temperature.
Water Cycle
The water cycle means the endless recycling of water.
Decay
Microorganisms break down plant and animal waste to get energy.
