yes they always begin with plants
Food chains start with green plants because only green plants are able to convert the suns energy into sugars that all creatures including plant need to grow.
Food chains always begin with a producer of some kind. A producer is an organism that is able to create food for energy from inorganic materials. Most of the producers on Earth are plants, algae, or cyanobacteria, all of which perform photosynthesis to make food.
Actually, the food chain begins with the Sun. Producers are just the primary energy source, which use photosynthesis to make food. Herbivores get their energy from the plant's sugar produced during photosynthesis.
Food chains always start with plants which are the producers then it will be followed by consumers and so on... CorrectionThey start of with the plants then the small animals then get bigger
Producers
there are often at the bottom of food chains. Plants

All food chains begin with plants. Small mammals consume plants or their seeds and these animals then become prey for rattlesnakes. Of course, rattlesnakes they are preyed upon by larger animals.
A source of Energy.
All food chains begin with the sun because it is the ultimate source of energy for almost all living organisms on Earth. Through the process of photosynthesis, plants and other producers convert sunlight into chemical energy, which is then transferred through the food chain as organisms consume each other.
No, ecologists use food chains to understand the flow of energy and nutrients in an ecosystem. They do not use food chains to control what animals eat certain plants.
