In this article we will discuss about the food chains, food webs and trophic levels of various organisms in the environment. Food Chains, Food Webs and Trophic Levels: 1. Food Chain: The transfer of food energy from the soured in plants through a series of organisms with repeated eating and being eaten, is called food chain (Fig. 48.2). a. At [...]
In this article we will discuss about the intraspecific and interspecific interaction between organisms. Intraspecific Associations: In intraspecific association individuals are quite similar in their resource requirements. This may often lead to intense competition. Intraspecific competition is a major force in ecology. To overcome or cope with competition, intraspecific competition may lead to behavioural adaptations such as dispersal and territoriality. [...]
The following points highlight the five main types of mutualism. The types are: 1. Obligate Mutualism 2. Facultative Mutualism 3. Trophic Mutualism 4. Defensive Mutualism 5. Dispersive Mutualism. Type # 1. Obligate Mutualism: Obligate mutualism is the relationship between mutualists which has evolved to such a point that the two species are fully dependent on each other. Here, none of [...]
