There are many different food chains, so there are many second links, but in general the second link in a food chain is two words and it is a primary consumer.
a plant
The last link in the food chain is typically apex predators, such as large carnivores like lions, sharks, or eagles. These predators are at the top of the food chain and have few or no natural predators themselves.
The first level of a food chain should always be a producer of some sort, such as a tree or plant. It is the start of the food chain - and without it, the entire food chain would fall apart and into pieces; as it would disrupt the order of the levels in a food chain.
The second link in a food chain is typically referred to as the primary consumer, which feeds on the producer (first link) and is then consumed by the secondary consumer.
because it needs a lot of energy to get the food chain to cycle.
