Yes. For example, you have grass, maybe trees, flowers, and other vegetation. Insects eat the plants, as do small mammals and birds.

Why do bees like blue flowers most of all?
Because insects can see purple, blue etc. better than red, orange etc. That's why tropical red flowers are almost always pollinated by birds, and red berries are eaten by birds; birds can see red better, insects can see blue better. Insects are also quite good with ultraviolet light, which is why many flowers have markings that are invisible to us, but visible to them - they can see colours beyond our vision.
