a a herd of bison - community
b a spider - organ system
c flowers and insects in a garden - organism
d a rock garden with various plants and rocks of different sizes - population
e a desert with little water, high heat, sand, cacti, and some mammals - ecosystem

Explanation:

An ecosystem is a community of living organisms in conjunction with the non - living components of their environment, interacting as a system. A desert with little water, high heat, sand (non - living), cacti, and some mammals (living) fits this definition. A herd of bison is a population. A spider is an organism. Flowers and insects in a garden are a community. A rock garden with various plants and rocks is not a population as it includes non - living rocks and multiple plant species.

Answer:

E. a desert with little water, high heat, sand, cacti, and some mammals - ecosystem
