Answer:
Apple tree and grass are producers, mushroom and bacteria are decomposers, and everything else are consumers. The bear is herbivore I believe, the rabbit is as well to my understanding. The pig is omnivore and lion is carnivore.
Explanation:
Starting with producers, most plants are producers. They photosynthesize to make their own food (glucose). Decomposers break things down like dead animals. Carnivores eat only meat, which is what a lion does. It eats no plants. The pig is an omnivore, meaning that it eats both meat AND plants. Lastly, the bear and rabbit are herbivores meaning that they only eat plants. I always remember it as "HERBivore which sounds like HERBS which are plants" Hope this helps!
