which organism ( grass, prairie, dog, ferret, or fox) do you think is a producer (does not depend on another organism for its food)?

grass

Explanation:

Grass is at the very bottom of the food chain and relies solely on sunlight and water, which aren't organisms. I'm going to assume you meant prairie dog because a prairie isn't an organism, but prairie dogs rely on grass for food. Ferrets rely on meat for food (which they get from other animals) and foxes rely on other animals for food as well. Therefore, grass is the only organism that is a producer (gives other organisms food) and doesn't rely on other organisms for food.

Grass

Explanation:

A producer or autotroph is an organism that produces its own food. These include plants, algae, and some bacteria. They convert carbon dioxide, water, and light energy from the sun into glucose, a type of sugar that provides energy, in the process of photosynthesis.

The organisms we are given are grass, prairie dog, ferret, and fox. The only plant is grass. Prairie dogs, ferrets, and foxes are all consumers, and depend on other organisms (plants, grass, leaves, or other animals for meat) for food.

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
