Answer:
B is the correct answer.
Explanation:
The sensory receptors in the nose send signals to the olfactory bulb. These signals are then processed by the brain, which sends a response. Olfactory bulb is the one that receives olfactory(relating to the sense of smell) information which is then relayed to other parts of the brain.

Answer:
Multicellular
Eukaryotic
Heterotrophs
Explanation:
Both cells of fungi and animals are eukaryotic meaning they have  nucleus and organelles. They are multicellular organisms (meaning they are composed of many cells). Their cells are also heterotrophic meaning they depend on organic molecules for energy as opposed to plants that can make their food from abiotic factors. Fungi, however, digest their molecules extracellularly while animals do it intracellularly. 
 
        
             
        
        
        
The primary consumers like rabbits or other small animals that are normally eaten by the secondary consumers (snakes) would over populate and eat all of the producers (plants) and the plants would die out. This would eventually lead to the decrease of the primary consumer (rabbit/small animals) population.
