Class Response- Energy roles

Right now in class we are learning about how organisms get their food and what their role is in the ecosystem. organisms can either be producers, consumers or decomposers. Here is some information on them:

Some organisms, like trees and almost all types of plants, can make their own food and they are called producers. Producers use a source of energy, like sunlight, to make their own food. Producers are at the bottom of the food chain and they are the source of all food in an ecosystem.

Consumers- Consumers are organisms who get their food directly or indirectly from producers. Because they can't make their own food they rely on producers for food and energy. There are three different types of consumers. The three types are:
Herbivores- organisms who only eat plants. Some examples are grasshoppers and rabbits.
Carnivores- organisms that only eat other animals. Some examples are spiders and snakes.
Omnivores- organisms eat both plants and animals. Some examples are bears and humans.

Decomposers- After animals die, organisms called decomposers eat their dead matter. Decomposers, such as as molds and mushrooms, are very important to the ecosystems because they get rid of animals' dead bodies. They also return the important materials of the dead animals back to the soil and water.

Current event- Solar powered MP3

Another new type of MP3 player has been created. This time it's a solar powered MP3 ceated by a company called Hong Kong Electronics Fair Autumn Edition in Singapore. The MP3 player, called Shiro SQ-S, has a 1.8-inch LCD display and a built-in FM radio and a 16GB of storage space. it also comes in three different colors and has a circular leypad like the Ipod. You can also watch videos and view photos on it. Also to charge your Shiro SQ-S fully all you have to do is leave it outside for a sunny day for four hours and if your Shiro SQ-S need more power but it's a cloudy day there is also a USB port.
