What is the fundamental niche width of an organism and what does it consider?

The fundamental niche width refers to the theoretical range of conditions that an organism could survive and reproduce in without considering interspecific interactions. It exclusively considers limiting biotic and abiotic factors such as appropriate food sources and a suitable climate. Signup and view all the answers
