Answer:Plants use carbon dioxide to make food
Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.
Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.
CO₂ + H₂O → O₂ + glucose (food)
This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.
There is no absolute reason as to how they survive besides organisms learning to adapt. In order to live in a polluted environment the animals have to survive and learn to adapt.
Assuming you are referring to plants when you say producers, bees help spread "pollen", or plant offspring from plant to plant, which helps to fertilize those plants and help new ones grow.
