Ecology Flashcards
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.
Temperature-Decay
The temperature causes faster rate of decay.
Oxygen-Decay
Oxygen availability is often a way in which microorganisms die as a result of decay.
Water-Decay
Water availability leads to decay to animals that are to weak to fight for water.
Number of decay organisms
The more microorganisms the faster decomposition happens.
Biogas
Methane is an biogas which can be burned as fuel.
Biogas-Fermenter
Biogas is made in a simple fermentor called a digester or generator.
Constant cycle of carbon
Carbon cycle
How many gigatonnes of carbon cycled through year
166000000000 tonnes of carbon
Green plants and alege
Green plants and algae remove carbon dioxide from atmosphere
How do green plants remove carbon dioxide
Photosynthesis
Combustion
Burning
Trees
Trees only give out carbon dioxide when they die
Photosynthesis
Carbon dioxide+water=glucose+oxygen
Respiriation
Glucose+oxygen=carbon dioxide+water
Combustion
Fossil fuel or wood + oxygen=carbon dioxide +water
Where does carbon dioxide dissolve in air
It is disolved in water particularly oceans.
Carbon compounds in fossil fuels
Only harm when burnt using combustion.
