9/29/14 Learning About Food Webs and Energy Pyramids Summary

1.          In AP Environmental Science class, we have been learning about food webs and energy pyramids. First of all, a food chain is where there is food/energy that is being moved from one level to the next. An example would be a woodland food web. The leaves are the producers that get their food from the sun, the earwig eats the leaves and gets energy there. The earwig would be a primary consumer who eats only plants. Just like a herbivore would. The third energy level would be the secondary consumer who eats the primary consumer. A secondary consumer eats only meat. In this food web, the earwig would get eaten by the ground beetle. To conclude this food chain, the wolf spider, which is a tertiary consumer, would eat the ground beetle and get energy through there. A tertiary consumer is a consumer that eats meat and plants. (***********) pyramids tie in with food chains.
            Each producer and consumer have a section of how much energy they consume. The energy is always measured by tens. Each energy level divide by ten as they go up. Like producers have 10,00, primary consumers have 1,000, secondary consumers have 100, and tertiary consumers have 10. All of the energy is released at heat at the end. In conclusion, food webs are energy that gets transferred to each producer and consumer.

2.        In my group's food web, we played a game where we had to get a food chain of animals that eat what and who. We had three people in my group including me. Once we had our food chains, we combined ours together to make one big food web.
           Our food web biome's would be a desert biome. We had the cactus plant, the rattlesnake, a hawk, and a coyote. All of these animals could thrive in a desert biome. These animals have their habitats located here and can survive in the harsh conditions.
