PLEASE HELP!! In a population, the number of organisms hovers around 10 per acre. When the number goes much higher, the organisms cannot find enough food, and some don't survive. When it goes much below, they thrive and reproduce quickly. What is the limiting factor in this example? *

food and land

Explanation:

A limiting factor is the one that limits the growth of any organism’s population. Here the population growth of an organism is limited by both availability of food and land. As the population grows, the food availability gets limited and hence most of the organism die.  

But when the population reduces, the food quantity becomes surplus and thus the organisms survive.  

Food and land

Explanation:

That is what it is a limiting factor of because they dont have the neccesary food and land
