Ecological niche

hide from predator. The polar bears (Ursus maritimus) eat mainly ringed and bearded seals located on the border of the Canadian arctic. Those seals are killed by polar bears during breathing holes depending on the availability of seals in the ecological niche (Stirling and Archibald 1977). However, arctic foxes and polar bears compete for the adults’ seals and the competition for food increase between them. It is not clear whether the polar bears feed with seals or are hunt by arctic foxes. If…

Description: One of the most critically endangered big cats with only 35 left in the world. They have been critically endangered since 1996. If the amur leopard becomes fully extinct this will cause the ecosystem to become unstable. Reasons why they are critically endangered/threats include habitat loss. It is estimated that between 1970-1983, the Amur leopard lost an 80% of its territory. They will have nowhere else to go. deforestation cutting down trees, Poaching illegal trade, prey being…

interactions among multiple organisms. Existing in an ecosystem are creatures attached to specific habitats and niches. An array of contrasting organisms maintains the balance in a fragile ecosystem, and the issue of overpopulation is avoided by the natural relationships between the predators and the prey. However, the introduction of a single foreign specimen is capable of disrupting an entire ecological community. Generally, the relocation of organisms results in invasive species, yet,…

In today’s society, school curriculums are filled with a variety of topics, from the Math’s to the Sciences, English’s to the Foreign Languages. One of the many items contained in school curriculums includes evolution. Evolution is a highly controversial subject in science that typically starts many debates with differing views on the subject. Some are for the teaching of evolution in public schools while others do not agree with evolution and does not want it taught to their children on the…

provided possible links between the activities of local hunters and deer population, instead of basing his logics on the hunters’ words. Moreover, he has also failed to suggest any reasons of decline due to human intervention and destruction of the ecological niche of the Arctic deer. Any supporting evidence, such as the number of deer killed by poaching, illegal trading or due to destruction of habitat would have strengthened his…

There are various types of insects in this planet, Earth. To survive in this planet, each bugs uses adaptation, which makes each insects unique and special. The definition of adaptation is “the ability of a species to survive in a particular ecological niche, …especially through natural selection.” (Dictionary.com) Through all the ‘adaptation skill’ that bugs use, this particular insect mentioned in article, Podisus maculiventris, uses a special skill when laying the egg. Podisus maculiventris,…

Paramecia, unicellular cilliated protozoa, usually are ovoid and elongated. They widespread in brackish environments and freshwater. Length of the species are various ranging from 50 micrometers to 330 micrometers. They feed on yeasts, algae, and small protozoa which are captured by them through phagocytosis, devouring a particle by “wrapping pseudopodia around it and packaging it within a food vacuole” (Campbell and Reece 2011). They also serve as the models for the study of basic biological…

People drinking water for many years that contains higher MCL for atrazine can suffer from cardiovascular or reproductive diseases. Also, it has ecological effects on birds and aquatic organisms, although it is only slightly toxic to birds and fishes found in those niches. Atrazine also inhibits photosynthesis in plants. In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are…

Creating customer value is an important element for a company securing a niche in competitive market. A company can create customer value to its customer base by providing the consumer with the best price, product and service. A consumer will place value on a fast food restaurant such as Chic-fil-A because they know they will…

Stomach content analysis provides important insight into fish feeding patterns. Feeding of fish represents an integration of many important ecological components that included behaviour, condition, habitat use, energy intake and inter/intra specific interactions, etc. Accurate description of fish diets and feeding habits also provides the basis for understanding trophic interactions in aquatic food webs. Conceptually, trophic relations of fishes begin with foods and feeding behaviour of…
