Answer:
Azimuthal map projections
Explanation:
The Azimuthal map projections come in a circular shape. They represent the whole world but in a different manner than that of the other map projections. The other map projections tend to have problems with the size of the objects as they get further away from the Equator, but this map projection doesn't have that problem. The Azimuthal map projections actually represent all of the places on Earth with their correct distances from the central point, and they all have their sizes correct proportionally to the scale, thus making an accurate map projection.
In what organisms are you referring to?
Say you have foxes and rabbits. They have a steady eco system because the rabbits breed and the foxes consume. This keeps the population consistent. If you add wolfs into the equation it completely throws off the balance because the wolfs and foxes will have competition. They will start to eat all the rabbits before they can multiply and the food sources will grow scarce thus upsetting the balance of that ecosystem. Hope this helped!
