What it niche?? What is "competitive exclusion principle"?? In the Lotka-Volterra competition equations, the parameter relates to what? What is parasite? An organism inducing disease in its host is called a _________. Example of the relationship between predator and prey; Lynx and hate populations both oscillate repeatedly, with a similar period (study tins!) In the Lotka-Volterra predation model, a prey (host) population in live absence of predators would ________? In a the Lotka-Volterra predation model, a predator population in the absence of prey (Hosts) would ____________? In most laboratory experiments, predators and prey held together m simple habitats exhibit repeated cycles in population sires. True or false? Which factors can stabilize predator-prey relationships by providing a prey refuge? What is community? A simple tree community consists of 4 maples, 3 oaks, and 1 alder. The species richness of this community is __________? Robot Mac Arthur's study of forest warblers suggested that warbler species diversity increases with habitat complexity. True or false? Estimates of the number of species present in a community can usually be made more easily by sampling only a single indicator taxon. True or false? Niches of single-celled algae, such as diatoms, seem most often to be distinguished by their requirements for _________? Concentrations of inorganic nutrients typically don't vary much across the surface of a single lake. True or false? What is disturbance? What is food web? What it mutualism?

Explanation / Answer

Niche is an ecological environment and adaptations of an organism in which he can utilize all the available (biotic and abiotic) resources and protects himself from predators, in order to survive successfully. Competitive Exclusion Principle states that Any two species who compete for the same set of resources cannot survive together. In such condition fittest of them will survive and other will perish or migrate from that niche. Alpha 12 is the effect that the species 2 imparts on species 1 population , after competition between the two. Parasite is an organism that lives in or on the body of another organism (host), and derives all his nutrients from it. The host is adversely affected by activities of parasite. For example Malarial parasite lives in Mosquito and human.
