each other compete for the light, nutrients and water) However, interspecific competition occurs

when two different species share a limited resource in a surrounding area, (ex: Rabbits are eaten

by eagles as well as coyotes both)

Ecosystems are constantly changing, so must the different species to adapt accordingly to

their environment. A joint observation is that as ecosystems mature through successional

stages, they tend to render more diverse and complex.



The number of organisms and species

increases and niches become narrower as competition for resources increases. (Turk, J. &

Bensel T. 2011) Thus, making different species adapt to the forest, grass land, give up or jungles.

An organisms ability to survive and thrive depends on the availableness of resources,

including light, water, and nutrients. Survival also depends on how that organism interacts with

other organisms and what behavior of niche it occupies within that ecosystem. (Turk, J. & Bensel T.
