A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).
An exoskeleton (external skeleton) is common in arthropods like insects, spiders, and crustaceans.
Part of the brainstem, the medulla is the connection between the brain and the spinal cord. It controls involuntary actions like breathing, swallowing, and heartbeat.
Secondary consumers (carnivores) subsist mainly on primary consumers. Omnivores are secondary consumers that also eat producers. Examples are rats, fish, and chickens.
