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

List six organisms that would be found in your schoolyard community. 2. This section will look at interspecific interactions. Be clear on the meaning of the prefix! To begin‚ distinguish between intraspecific competition and interspecific competition. Give an example of each. Type of Competition

The last type of relationship is parasitism. It is parasitism when one symbiont benefits while the other is harmed. An example is the human and the tapeworm. The tapeworm derives food and shelter from the human host‚ while the human is denied of the nutrition that is consumed by the tapeworm. Perhaps

different groups using hierarchical rankings ; Genus and species. 5. What is a species? Define the biological species concept. A species is a living organism which follows the biological species concept of parasitism‚ commensalism‚ and mutualism. The biological species concept: Parasitism: one benefits from the other; taking over a host‚ (+/- reaction) (Ex: plasmodium apicomplexa taking over a human host causing malaria‚ tapeworm) Commensalism: one benefits and one doesn’t care‚ (+/0 reaction)

31. Molds and mushrooms are similar in the process of reproduction. They both reproduce asexually through the process of sporulation. Why these organisms reproduced anywhere? a. because the spores are lighted directly by the sun. b. because the spores are transported by air and wind. c. because the spores are very small and heavy. d. because the spores are grafted to another plant. 32. In flowering plants‚ there are two events that lead to reproduction. What are these two events? a. Fertilization

An ecological community consists of all the interactive species living within a certain area or a certain habitat. Most species have interacted over a long period of time. The interactions fall into categories including commensalism‚ competition‚ parasitism‚ predation‚ and mutualism. Commensalism is when one species will

Some possible interactions between the two species were neutralism‚ commensalisms‚ mutualism‚ and parasitism. It was hypothesized that the relationship would be commensalism‚ with Spanish moss benefited and the Southern live oak neither benefited nor harmed. The type of symbiotic relationship was determined using two factors‚ the relative health of the

Competition- (–/– interaction) occurs when species compete for a resource in short supply example when an invasive species moves in it cause competition. Large insects defend feeding sites on cottonwood leaves by kicking and shoving smaller aphids from better sites. Predation- (+/– interaction) refers to an interaction in which
