Living Flashcards
Define abiotic
Non living things
Biotic
Living things
Decomposer
Organism such as bacteria or fungus that breaks down dead tissue which is then recycled to environment
Ecosystem
Community of plants and animals that interact
Food chain
Connection between different organisms relying on one other as a source of food
Food web
Complex hierarchy of plants and animals relying on each other for food
Producer
Organism or plant thats able to absorb energy from sun for photosynthesis
What abiotic factors can biomes be defined by
Climate
Steepness
Geology
Soils
Vegetation
Where are tropical rainforests found
Within the latitudes of Tropic of Cancer and Capricorn
One reason why energy is lost at each level in a food chain
Respiration
Whole organism is not consumed
Why is nutrient recycling very fast in rainforests
High humidity
Warm conditions
Lots of plants that decay
Biodiversity
Range of plants and animals and it is high in a rainforest
Why is there a high amount of biodiversity in rainforests
In tropical area so there’s more sunlight meaning more photosynthesis and more plants
Describe weather conditions is rainforests
Sun is directly overhead so they’re hot all year
Also wet due to rising air creating clouds and cooling and condensing triggers heavy rain
How to work out percentage change
Old number - new number
Divide by old number
X by 100
Why are rainforests important
Hold 50% of worlds plants and animals (biodiversity)
Absorb carbon dioxide slowing global warming
Why are rainforests being cut down
Logging - chopping trees to sell for timber
Palm oil- cut down trees to grow palm oil trees
