**Producers** are living thing that make their own food, and provide energy for consumers//.// They are plants, algae, and certian bacterias. Producers are also known as **autotrophs**. They get energy from the sun and from chemical energy. The producers that get their energy from the sun are called **phototrophs**. How they get their energy from the sun is a process called **photosynthesis**. These producers transform carbon dioxide and water into oxygen and carbohydrates. Without photosynthetic producers, their wouldn't be enough oxygen in the air to breath. **Why is it important to understand how living organisms interact with each other and their environment?** We need to understand how living things interact with the enviroment so that we don't take away that animals eneregy source. Also to know how animals live so we can act upon it no not make them go exctinct or to become a rare speices, like so many other animals have. We need a lot of the animals to stay because we need them. For example we need pigs and cows for food. Some animals eat the bugs that are annoying and harm other plants or animals. If we don't keep the enviroment clean the air can become polluted, and make it difficult for us and other things to breath. We also take away animals homes when we build new buildings and expand our cities or chop down trees for paper. Those animals then have to go look for another place to live. Without an understanding of what roll different organisms have on their enviroment we won't know how   we can effect the enviroment for all living things.

 * Chemotrophs**, obtain their engery from chemicals such as hydrogen sulfide or other inorganic chemicals. They change the chemical energy into carbohydrates by a process called **chemosynthesis**. They mostly live in remote place, but some live in more common places. Producers provide energy to some consumers.

They are also known as **heterotrophs**. **Herbivores** get their energy by only eating plants. **Carnivores** get their energy by eating other other animals//.// **Omnivores** eat both plants and animals to obtain their energy. **Detritivores** eat the animal remains and dead matter. To get their energy **decomposers** break down the organic matter. Consumers depend on the producers for their energy.

 * Autotrophs**: organisms that can capture eneregy from sunlight and chemical use it to produce its own food from inorganic compounds
