with a plant. Plants provide food for ALL organisms‚ either directly or in directly (directly - animals eat plants or indirectly - animals eat other organisms which ate plants). The position an organism occupies in a food chain is called a trophic level e.g. producer‚ primary or secondary consumer. A SIMPLE FOOD CHAIN plant → animal eats plant → animal eats animal (producer) (primary consumer) (secondary consumer) E.g. cabbage → caterpillar

is a continuous variable that provides a measure of the passage of energy and an index of ecological structure that increases in value counting progressively through the linkages in a linear fashion from the lowest to the highest trophic (feeding) levels.[7] Food chains are often used in ecological modeling (such as a three species food chain). They are simplified abstractions of real food webs‚ but complex in their dynamics and mathematical

Introduction Last week‚ my Biology class and I went down to the Port Kembla Rock Platform. While we were there we surveyed five different sectors about the rock platform and recorded them‚ these included: 1. Surveying the abiotic characteristics of the rock platform 2. Observing the abundance and distribution of the Black Periwinkle (Nerita Atramentosa) 3. Observing the feeding relationships and food webs of the organisms 4. Finding the adaption’s of organisms 5. And Observing the human impacts

to as being tri-trophic. Due to nature’s complexity and the millions of extant species of plants and animals‚ cascading trophic effects are capable of running through multiple trophic levels. Depending on the species‚ or location‚ effects from apex predators can cascade through four‚ seven or twenty trophic levels. The occurrences of trophic cascades have been recognized in all of Earth’s major

juvenile stages that feed at a low trophic level‚ while the adults feed at a tertiary or quaternary trophic level? By having them feed at different trophic levels they are not competing for the same foods. The foods the adults eat are not the foods the juvenile eats so they are not intruding and competing against each other. That separation in trophic levels assists in the survival of the juveniles to the adult stage. 4. Not all adults feed at a high trophic level. Whale sharks (50 ft) are the largest

There was much diversity between Mediterranean Sea and Indian Ocean trade. For example‚ in the Mediterranean‚ sailors used square sails and long banks oars to maneuver among the sea’s many islands. But the traders of the Indian Ocean built sails the shape of triangles and did not use oars. Another example would be that the Indian Ocean ship builders would make the ships by piercing and tying planks of wood and then caulking them together with bitumen. The shipbuilders of the Mediterranean‚ however

Write a commentary on one of the following: The music of the ship was howling around him. The low whistlings; the tortured rumbles; the wheezy sputters of breeze flowing through it. The clatter of loose wainscoting. The clank of chains. The groaning of boards. The blare of wind. Never before had he felt rain quite like it. It seemed to spew from the clouds‚ not merely to fall. He watched the wave rise up from a quarter of a mile away. Rolling. Foaming. Rushing. Surging. Beginning to thicken and
