What is an Input?
Something that’s put into a system

How nutrients move between the stores
How are nutrients transferred to the soil in the rainforest?
Through decay?
How does the soil loose nutrients in the rainforest
Through leaching
What does the biomass store in the rainforest receive nutrients from?
Growth
What is a food chain?
A chain that shows how nutrients and energy are passed on from one creature to another
What’s a food web?
A web that shows the interdependence of animals in different species as all the food chains in the ecosystem
