Some dinosaurs had sclerotic rings. A secondary compound is a chemical manufactured by a plant that protects it. Most fossils are found sedimentary rock. The seed is excreted in the stool, and the seed is spread away from the parent plant. A seed predator is an animal that eats and destroy seeds instead of eating the fruit and leaving the seed or dispersing the seed in the stool.
Parrots are seed predators.
Seed predators limit the number of viable seeds. Serrated teeth are good for cutting through flesh. Tactile setae are long hairs that butterflies and moths use to sense touch. These hairs are attached to nerve cells, and relay information about touch to the insect's brain. Setae grow through holes in the pinaculum of the exoskeleton .
