Section I.1 Tolerance (a) Tolerance: the ability to survive and reproduce under a range of environmental circumstances (b) Habitat: the general place where an organism lives Section I.2 Defining the Niche (a) Niche: describes not only what an organisms does‚ but also how it interacts with biotic and abiotic factors in the environment (b) A niche is the range of physical and biological conditions in which a specie

ways in which food chains can be interlinked to form a food web. If one member of the food web is affected‚ this will in turn affect other food chains in the web. Commensalism In ecology‚ commensalism is a class of relationship between two organisms where one organism benefits without affecting the other. It compares with mutualism‚ in which both organisms benefit‚ and parasitism‚ when one benefits while the other is harmed. Example: *Shark and Remora* The remora attaches itself to the

of life. Ecological succession can change a community by making exponential changes to the ecosystem over time‚ symbiotic relationships are important in maintaining a stable ecosystem because they provide competition‚ parasitism‚ mutualism‚ and commensalism to have balanced populations‚ and the impact of a change in the food web would be drastic to the ecosystem because one change can and will alter the life of every animal in the ecosystem. Ecological Succession is predictable changes

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

of relationship between organisms can be divided into two 1)Positive interaction-which is beneficial to one or both partners. These include a) commensalism b)proto co-operation c) mutualism 2)Negative interaction-which is harmful to one or more of the participants. These include a)competition b)predation c)parasitism d)amensalism and e)antibiosis MUTUALISM-is an association between two or more organisms in which all is mutually benefited without any harm.

are three types of symbiotic relationships that include; commensalism‚ parasitism‚ and mutualism. Along with the symbiotic relationships there are also two types of competitions; interspecific and intraspecific competition. Competition is when two organisms fight for the same limited resources. Commensalism is when there are two different organisms and one organism gets benefits without harming the other. One example of commensalism is between a Florida red belly turtle and the American Alligator

Valleser BS Bio August 2‚ 2013 Animal Systematics (ZOOL102) A Literature Review on Symbiotic Relationship between Clownfish and Sea Anemones Symbiosis is a close and often long-term interaction between two or more different biological species. It comes from the ancient Greek words syn meaning “together” or “with” and vios meaning “life” (ODZ). Symbiosis is fundamentally classified as ectosymbiosis and endosymbiosis. Ectosymbiosis or exosymbiosis is a type of symbiotic relationship

Species interact with each other in these different ways: interspecific competition‚ predation‚ parasitism‚ mutualism‚ and commensalism. 4. As environmental conditions change‚ one species may be replaced by other groups of species. This gradual change in the composition of species in a given area is called ecological succession. 5. A community has three aspects of
