When you go down the food chain by asking the question “what does it eat” at what category of living things do you always end up subject: mystery science chapter: food chains

The correct answer will be- autotrophs or plants.

Explanation:

The food chain represents the flow of energy and matter between organisms. The food chain begins with autotrophs or plants which can synthesize the food on their own. These plants are eaten by the herbivores which get eaten by the carnivores.

When these are arranged in the categories then the autotrophs is positioned at the bottom of the pyramid whereas the top carnivore at the top.

If we will go down the category of the food chain then autotrophs will come at the bottom and thus autotrophs or plants is the correct answer.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
