All consumers, including humans, depend on producers because they make all of the food for the rest of the food chain.
Plants produce edible seeds and fruits after pollination (transfer pollen from the anthers of flowers to the stigma).
Many plants depend on animals such as insects to pollinate them, and on animals such as birds to disperse their seeds.
Because of food chains and pollination, producers and consumers are interdependent.
Pollinators are important, ensuring there is food security for humans (having enough food to feed the human population).

The interdependence of organisms within ecosystems arise from more than just feeding relationships.

This lesson demonstrates that feeding relationships are important and that producers often rely on consumers for reproduction.

Producer - A producer is an organism that makes its own food.
Pollen - Grains of pollen carry genetic material between flowers to enable flowering plants to reproduce.
Pollination - Pollination is the process where pollen is transferred to the female organs of a plant, to enable seeds to be made.
Interdependent - Organisms are interdependent when they rely upon each other for their survival.
Food security - Food security is having enough food to feed the human population.
