Science Review Sheet: Sustainable Ecosystems 1. Carrying Capacity: The carrying capacity of a biological species in an environment is the population size of the species that the environment can sustain indefinitely‚ given the food‚ habitat‚ water and other necessities available in the environment. In population biology‚ carrying capacity is defined as the environment’s maximal load‚ which is different from the concept of population equilibrium. Population size decreases above carrying capacity

Introduction Competition is an important interaction that occurs between living organisms that co-exist in an environment. All living organisms need certain resources in order to survive and reproduce. These resources include but are not limited to nutrients‚ food‚ water‚ and a space to live in. When these resources become limited in a shared area‚ organisms are forced to compete with each other for the resources that they need. This competition can occur among individuals belonging to the same

Diseases caused by Metazoan Parasites Metazoan parasites are multicellular‚ macro in size with complex organs‚ direct or indirect life cycle‚ and evolved to have specialized morpho-adaptation for parasitism. Metazoans include a diverse group of parasites‚ viz.‚ myxozoans‚ helminths (monogeneans‚ digeneans‚ cestodes‚ nematodes and acanthocephalans)‚ crustaceans (copepods and branchiurans) and hirudineans. Myxozoans Myxozoans are coelozoic and histozoic metazoan parasites with microscopic body

Life cannot exist without energy Energy flows in one direction thru the ecosystem eg. Green plants (autotrophs) harness light energy from the sun. An another consumers eat the autotrophs and other consumers. This flow of energy is a consequence on the laws of thermodynamics‚ were in sense that energy can neither be stored or created‚ but is transferred from one type to another. At which sun is converted to heat. The transfer of energy in an ecosystem‚ can be showed in a number of ways eg as a
