A scientist who classifies organisms is a taxonomist.
Limited resources in an ecosystems would be
Land/territory
<span>Food </span>
<span>Water (in terrestial ecosystems) </span>
<span>Sunlight (mostly for plants) </span>
<span>Nutrition in the soil (again, usually for plants) </span>
Uniform Cells because when they differentiate they form a new type of cell for the plant that they are inside of! Hope that helps!
