As you might imagine, a food web in the tropics looks very different from the one you created. Environmental conditions (temperature, light, nutrients) are different in the two areas, so it would make sense that the organisms that live in those areas might be different also. What might a food web from a tropical marine environment look like? How about one from a temperate coastal area?

Divide into groups to create your own food web games. Use books and the internet to find information about the areas listed below or think of some on your own. 1) The west coast of South Africa - This is an area often associated with phytoplankton blooms. PAcast. KS3 Bitesize: Science - Food chains - Food chains. Biosphere: Food Chains. Everyone plays a specific role in the food chain of life. You might be a human thinking they are king of the hill or you might be a bacterium under the feet. You are very important to the survival of the system no matter what role you play. As you study more about ecosystems and cycles in life, you will see the terms food chains and food webs. They describe the same series of events that happen when one organism consumes another to survive.

Food web is a more accurate term since every organism is involved with several other organisms. Cows might be food for humans, bacteria, or flies. Producers are the beginning of a simple food chain. There are also photosynthetic protists that start food chains. Consumers are the next link in a food chain. Secondary consumers eat the primary consumers. In some ecosystems, there is a third level of consumer called the tertiary consumer (that means third level). There are also consumers called omnivores. The last links in the chain are the decomposers. Timelapse: 74 days of fruit decomposing. Quiz Game : Ecosystems : Producers & Consumers. Kid's Corner - Food Chain Game.

Food Chain - Kid's Corner. The Food Chain Every living thing needs energy in order to live. Everytime animals do something (run, jump) they use energy to do so. Animals get energy from the food they eat, and all living things get energy from food. Plants use sunlight, water and nutrients to get energy (in a process called photosynthesis).

Energy is necessary for living beings to grow. A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. A simple food chain could start with grass, which is eaten by rabbits. Producer Consumers - Food Chain - Kid's Corner. Parts of the Food Chain (Producers/Consumers...) Producers Plants are called producers.

This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food - in the form of glucouse/sugar. The process is called photosynthesis. Click on the image below to learn about photosynthesis. Consumers Animals are called consumers. Decomposers Bacteria and fungi are decomposers. Is It Alive? Natural vs. Man-Made. Natural vs. man-made is a hard concept for nine year olds to grasp when they live in a techno-world where real is fake and fake is real. I attempted to introduce this topic to them today. Students were given a pristine sheet of white paper. Luckily I remembered to remind them not to make any marks including their names on the paper until they received instructions.

If I hadn’t given that instruction I would have had several Picasso’s in the room before I had handed out all the paper. I asked students to fold the paper in half from top to bottom and make a crease in it. As I instructed them I modeled what I wanted them to do. Once their paper was creased students were asked to open their paper up. Most everyone got the basic shape. I then asked students to redraw their map in the bottom half of their paper now that they had a model to go by on the board. I kept taking responses until almost everyone had suggested something.
