A producer.
All food chains begin with a producer, typically a plant or algae that can photosynthesize and produce its own food. These producers form the basis of the food chain by converting sunlight into energy that is then consumed by organisms higher up the chain.
Producers
Food chains start with producers, such as plants, algae, or photosynthetic bacteria that produce their own food through photosynthesis. These producers form the base of the food chain by converting energy from the sun into organic compounds that can be consumed by other organisms.
It depends.In some food chains, a spider is a predator because it traps its food in webs. It will eat organisms such as flies.In other food chains, Spiders are prey. They will be eaten by organisms such as birds.
Organisms that produce their own energy using sunlight are photosynthetic organisms. These are plants or other organisms that contain chloroplasts.
producer.
The kind of organisms that are at the start of most food chains are producers. Producers make their own food and animals feed off of them.
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.
The small organisms that are the base of aquatic food chains are called plankton.
Photosynthetic micro organisms make their own food
