yes because if it wasn't then the herbivore can't eat.
Bacteria is a producer.
All food webs have a producer that grows the foodstuffs, a wholesale/supplier, a seller- as in a food store, and a consumer/customer.
i think they're the plants and moss
Food webs consist of different plants and animals, food chains are just animals in an environment with a producer, top consumer, and animals in the middle who are consumers.
Producers, such as algae, are generally the first (or bottom) step of a food web. They use sunlight to photosynthesize their own food, hence the name producer. Other animals above them in the food web depend on the producers as their main source of food.
Food chains and food webs are different. This is because the webs have more relative food choices whereas the chains are limited.
In most food webs the Sun is the ultimate source of energy. Some food webs start with chemotrophs and in those cases the source of the energy are chemicals often from underwater volcanoes.
there wouldn't be a food chain without the producer. it has to start somewhere with some thing.

Food webs and food chains are mostly the same
