Explanation:
Omnivores are animals that eat both plants and animals. If you look at the bottom of the food web, you need to look for arrows that point towards an animal that also consumes other animals. The arrows indicate that the energy is being transferred from the plants to the omnivore. The Raccoon is the other organism that eats both a producer (blackberries) and other predators such as garter snakes and meadow voles.

A dichotomous key helps you identify unknown specimens based on their traits because there are only two options available per trait. Selecting one from the two options (usually contrasting characteristics) from each step leads to smaller and smaller groups until the option is reduced to single and unique trait of an organism.
Considering you need to identify an organism. So, on the top of they key is animal with options: (a) with red blood cells and (b) no red blood cells. The option you will select is no red blood cells and under option b, you’re given two choices again: (a) hard bodies and (b) soft bodies. You’ll select soft bodies, then two options again are given: (a) with shell and (b) without shell. The option you’ll select would be without shell, and so on.
