Food Chain: A sequence that links species by their feeding relationships. Herbivores: Organisms that only eat plants. Carnivores: Organisms that only eat animals. Omnivores: Organisms that eat both plants and animals. Detritivores: Organisms that eat detritus‚ or dead organic matter. Specialist: A consumer that primary eats one specific organism. Generalist: Consumer that has varying diet. Trophic levels: The levels of nourishment in a food chain. Food Web: Shows the network of feeding relationships

business began in 1940‚ with a restaurant opened by brothers Richard and Maurice McDonald in San Bernardino‚ California. Their introduction of the "Speedee Service System" in 1948 furthered the principles of the modern fast-food restaurant that the White Castle hamburger chain had already put into practice more than two decades earlier. The original mascot of McDonald’s was a man with a chef’s hat on top of a hamburger shaped head whose name was "Speedee." Speedee was eventually replaced with Ronald

water and sunlight. In a typical ecosystem‚ plants and other photosynthetic organisms are the producers that provide the food. (Leibold) Ecosystems can be permanent or temporary and they usually form a number of food webs. Examples of ecosystem include: Marine Ecosystems: oceans‚ coral reefs‚ intertidal zones‚ estuaries (harbour‚ lagoons) Terrestrial Ecosystems: deserts‚ forest‚ grasslands‚ tropical rain forests‚ tundra‚ taiga Freshwater Ecosystems: streams‚ rivers‚ pond‚ lake‚ swamps and marshes

The Ecosystem - Deserts An Ecosystem is a biodiversity community where biotic and abiotic elements inhabit the same environment. There are many types of ecosystems located throughout the world and one of which is known as the Gobi desert. The Gobi is a large desert region that scales from 500‚000 square miles and spans across two countries (China and southern Mongolia) covering parts of northern and northwestern China. Like all deserts‚ the Gobi desert is a cold biome desert that consists

In both agricultural and arable farming‚ there has been an increase in the pressure to provide plentiful and available good quality food at low prices for consumers. This has led to the development of not only a highly competitive market‚ but intensive methods for farming to have been designed.

Desert Marcus Green SCI/230 11/11/2012 Yasmin Henry Desert biomes can be defined as sandy regions that have very little rainfall as less than 50 cm a year with extreme temperatures and very scare vegetation. The fact that deserts are so dry the temperatures can change drastically‚ during the day temperatures can be as hot as 32 degrees Celsius‚ but at night temperatures can drop as low as -4 degrees Celsius because when the sun goes down there is no moisture in the air to trap the heat

The algae shut down fishing for crabs in most of California. This algae is also affecting sea lion babies. The problem is caused by warm ocean water. Their food source comes from cold water‚ but when the water is warm there is not enough food for mother sea lions. Mother sea lions cannot make milk without food. The babies are hungry and are super thin. The experts biggest worry is pregnant mothers since are more vulnerable to the illness because they consume more fish while pregnant
