Ecology Definitions Biogeography refers to geography in relation to living organisms. It studies the distribution of organisms’ geographically‚ and tries to understand the reason as to why a certain organism will prefer a certain locations compared to another. It then goes ahead to use the information discerned to describe what conditions favour different organisms. Abiotic Nonliving‚ as in abiotic factor‚ which is a nonliving physical and chemical attribute of a system‚ for example light

. . . a nest of parasites hanging from the neat sunlit town‚ eating its substance‚ giving no nourishment back. Yet to K lying idle in his bed‚ thinking without passion (What is it to me‚ after all? he thought)‚ it was no longer obvious which was host and which parasite‚ camp or town.

In economics‚ a compensatory test is applied for “evaluating public policy choices” (Kenyon 258). The test compares existing policies to suggested policies and the suggestion is only accepted if the prospective gainers can compensate prospective losers without leaving any individual worse off (Chipman). So‚ what if this test were used to evaluate “policies involving the gain or loss of human life” (Kenyon 258)? In such a scenario‚ it may be proposed that society could only continue to benefit because

Section 1 1. Define mutualism and commensalism. Mutualism- Both are benefited Commensalism- One benefits the other doesn’t care. 2. Give examples of mutualism. Oxpeckers (a type of bird) and Zebras‚ the Oxpecker picks ticks and parasites off of the Zebra. The oxpecker gets food and the Zebra gets pest control. 3. Explain why most parasites do not kill their host. Why is it in their own best interest to keep their host alive? If a parasite kills its host the parasite will most likely die too Section

Mutualistic relationship of young desert plants and nurse plants. By: Anthony J. Johnston University of Arizona Abstract- The project being presented is on the association of desert plant life with nurse plants. It is said that desert plant life such as C. Gigantea‚ Ferocactus Wislizeni‚ and Ambrosia Deltoidea‚ associate themselves with other large nurse plants for protection‚ and other resources. Results showed that there was no random association of this hypothesis; therefore the null hypothesis

Individual plants and animals could not exist by its self on earth. All organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water

1. Parasitism - one organism‚ known as a parasite‚ lives in or on the other organism‚ known as the host‚ from which it derives nourishment. It is not in the best interest of the parasite to kill the host. 2. Deserts - receive less than 25 centimeters of rain per year; windy. 3. Tundra-permanent frozen layer-permafrost; found north of Taiga and in small patches on the mountain tops called alpine tundra. No trees can live here. During a brief 2 month summer‚ the top layer thaws‚ and many
