Abiotic
non-living thinks
Ecosystem
a natural system made up of plants, animals and the environment
Biotic
Living things
Producers
Convert energy from the mainly sunlight into sugar. the most obvious producers are plants that convert energy from the sun by photosynthesis.
Consumers
get energy from the sugars produced by the producers. E.g. a pond snail, because it eats plants.
Decomposers
They break down plants and animal material and return the nutrients to the soil e.g. Bacteria, funghi
Food web
Shows the connections between producers and consumers in a rather more complex way
Nutrient cycling
foods that are used by plants or animals to grow
Two main sources:
-rainwater washes chemicals out of the atmosphere
-weathered rock releases nutrients into the soil
When plants or animals die, the decompisers help them to recycle the nutrients making them available one again for the growth of plants or animals.
