Introduction Ecology may be broadly defined as the study of the interrelationships or interactions among the different components of the ecosystem. All the ecosystem components are directly and /or indirectly linked with one another. “There is constant interchange of various kinds within each system‚ not only between the organic and inorganic” (Tansley‚1935). The linking forces are two processes: the energy flow process‚ and the biochemical cycle. In other words‚ ecosystem components are

provide for our food chain in different ways. You have herbivores which eats our plants such as a squirrel or cow. You have carnivores which are meat eaters. They supply many of the animals we don’t usually eat such as lions and tigers. You then have omnivores which supply our bears and pigs because they can eat plants and meat. As you can see many of these natural resources are used to supply all of our animal’s food for their survival. Natural resources were cared for in a better manner years ago. Cave

Basic Ecological Concept Levels of Organization Cells- are composed of Cell Membrane‚ Nucleus and Protoplasm. Tissue-is an aggregation of cells performing a common function or functions. Organs- is the aggregation of tissues usually forming a definite shapes‚ and performing a definite function within an organ system. Organ System-is a group of organs that perform coordinated functions together to keep the organism alive and functioning well. The scope of the biology includes the study of all

When you hear‚ the word endangered what comes in mind? Endangered means a species of animal that is at risk of extinction. Do you ever wonder what kind of animals that are endangered? There are multiple of animals that are endangered and one of them is the Western Lowland Gorilla. The Western Lowland Gorilla is found in Africa (Earth’s Friends). The Western lowland gorilla is one of the most recognized wild animals around the world (Earths Friends). This incredible subspecies is native to Africa;

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

For instance‚ Shubin relates that “The bumps‚ pits and ridges on teeth often reflect the diet” (Shubin 60). By knowing the diet of an ancient creature‚ it is reasonable to see how a paleontologist and evolutionist can follow the emergence of the omnivore over the carnivore and herbivore. And the hardness of teeth make it the “best-preserved animal we find in the fossil record for many time periods” (Shubin 61). This clue to these ancient animal’s diets can “give us a good window on how different

conveniently happened to stumble upon PETAs website in my elementary school ’s computer lab. After watching multiple investigative videos of the gruesome animal slaughters occurring in factory farms‚ I‚ much to my parents’ dismay‚ renounced my title of an omnivore and adopted the vegetarian diet. However‚ a ten year old girl does not have many vegetarian peers in Catholic school. I consequently turned to vegetarian forums for moral support and conversation concerning this new lifestyle of mine. Over the past
