Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.
Explanation:
Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

Producers are found at the bottom of the energy pyramid because they take in the sun's energy and convert it to large amounts of plant energy.Therefore, animals on the next level will gain energy from eating the plants directly and then the energy will continue to pass on from level to level as the food chain continues.
