Group IV of the Periodic Table of the Elements contains carbon (C), silicon (Si) and several heavy metals. Carbon, of course, is the building block of life as we know it. So is it possible that a planet exists in some other solar system where silicon substitutes for carbon? Several science fiction stories feature silicon-based life-forms--sentient crystals, gruesome golden grains of sand and even a creature whose spoor or scat was bricks of silica left behind. The novellas are good reading, but there are a few problems with the chemistry.

CRYSTALLINE CREATURES? Silicon can grow into a number of lifelike structures, but its chemistry makes it unlikely that it could be the basis for alien life-forms.</span>
Indeed, carbon and silicon share many characteristics. Each has a so-called valence of four--meaning that individual atoms make four bonds with other elements in forming chemical compounds. Each element bonds to oxygen. Each forms long chains, called polymers, in which it alternates with oxygen. In the simplest case, carbon yields a polymer called poly-acetal, a plastic used in synthetic fibers and equipment. Silicon yields polymeric silicones, which we use to waterproof cloth or lubricate metal and plastic parts.
The Sun provides energy for the plants (producers) to grow. Herbivores (primary consumers) then eat the producers for energy. Any animals that eat the herbivores are considered secondary consumers. As this cycle continues, energy is lost to the environment as heat.

<h2>Further Explanation
</h2>
a botanist is a scientist who is an expert in the field of plants. In this way, in botany, all the knowledge learned about biologies, such as genetics, reproduction, growth, metabolism, development, interaction with biotic components and abiotic components, and evolution associated with plants.
