Because they can't eat any other living things.
In the food chain, plants are producers ( because they make oxygen thru the process of photosynthesis.)
'Producers' are suppliers of food chain. Producers generate their own food and are not dependent on others. Producers are usually plants (green plants)

energy
with plants
Food chains start with green plants because they are able to produce their own food through photosynthesis, using sunlight, water, and carbon dioxide. This makes them the primary producers of an ecosystem, providing energy for all other organisms in the food chain through their consumption by herbivores.
If you have a food chain then the chain must have a beginning (where the food is made) and an end (where the food is finally all used up). Thius in a food chain the "producers" of the food (the plants) are ALWAYS the start. The plants make food using CO2 from the air, Water from the ground and the energy they collect from Sunlight. It is the passing on of this energy from the Sun that is the chain.
The sun is the very first thing on a food chain.
Green plants that are at the bottom of the food chain
Primary producers
Yes, grass is a green plant. All green plants are producers.
Algae and green plants are primary producers in the food chain, forming the base of many aquatic and terrestrial ecosystems. They convert sunlight into energy through photosynthesis, serving as a crucial energy source for consumers higher up in the food chain.
