    basically, individuals build up population--> diff pops-->community (1 area)-->diff communities (more than 1 area) --->ecosystem (the whole system which includes biol and physical.)

    eg.

    human+s (human population)

    humans+ cats/dogs/rats in the same house (community/ region) <--diff spp

    my house and other houses nearby (communities)

    interaction wif neighbours (eco <--not a gd example of this but use ur imagination)

    Toucans, parrots, tree snails, and beetles

    diff species= family members+cats/dogs/rats living together

    Oak trees, humming birds, soil

    ecosystem if they interact since soil is a physical factor

    soil provide space, nutrition n water to oak trees, oak trees provide living space n food to humming birds, birds shit (nutrition) back to soil
