What is a pioneer species?
It’s a species that that are capable of being the first to colonise distributed or newly formed enviroment
Define primary productivity
It’s the rate which energy is converted into organic material through photosynthesis
The total amount of biological productivity within an ecosystem is known as the gross primary productivity
What is net primary productivity?
It’s the amount of energy captured minus the energy used to respire
What does g/m2/year represent
It’s the gross primary productivity (GPP)
What is the equation gives the gross primary productivity?
Energy production per unit area / unites of time
/ means divided
What is a native species?
They are species that organised and developed in a single ecosystem or region and adapted to living in that area
Define indigeonous
originating or occuring naturally in a specific area a special that is native to an ecosystem
What is the boreal forest also known as?
