I don’t get what a niche is… 🙁
I know its a role of an organism in an ecosystem that allows it o survive, grow and reproduce indefinitely, but does anyone have an example?

i am doing a project on invasive species, and i need to know the niche of the carpet burweed, ie. the function a species serves in an ecosystem, including what it eats, what eats it and how it behaves.
for background information, it is a small weed that has seeds that attach to fur, paws, skin etc. and thrives in open fields (eg. open parks, golf courses).
thank you 🙂
