Food chain is a linear sequence of transfer of food and energy when one organism is consumed by the other organism. The food chain exhibit different trophic levels based upon the type of organism and type of food it obtains. In the producer level there are plants which produces their own food. These plants are consumed by the herbivores called as primary consumers. These herbivores are consumed by higher organisms for example, rat is consumed by snake. The secondary consumers are carnivores. These secondary consumers are consumed by other higher consumers such as tertiary consumers.
The rabbit is an herbivorous animal which feeds upon grass, and vegetables. Therefore, it belongs to the primary consumer level of the food chain.

It is problematic due to antibiotic-resistance that would
occur. This extensive use and abuse of antibiotics result in the emergence of resistant
strains of bacteria. Some types of
bacteria that cause serious infections in humans have already developed
resistance to most or all of the available treatments, and there are very few
promising options in the market.
