Answer:
Plant-eating animals are called PRIMARY CONSUMERS.
Explanation:
In an ecosystem, consumers are heterotrophic organisms that can not make their own food. They rather depend on producers or other consumers for food and nutrition. The organisms that derive their nutrition directly from plants are called primary consumers. They are also called herbivores as they feed on plant and plant products. For example, deer graze grasses. This makes deer a primary consumer and a herbivore.
Pericardium is a membrane that surrounds the heart and the roots of the blood vessels. It is composed of two layers: the serous layer and the fibrous layer.
The Pericardium keeps the heart in place and in proper working order. Any disorders that occurs in the pericardium will also affect how the heart works.
Inflammation of the pericardium may be a result of infection, heart attack, heart surgery, and other medical side effects.
