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

1- Define abiotic and biotic components of the environment. Natural environment includes all the living and non-living components occurring naturally on Earth. The biological components of the ecosystem that is the biotic components interact with the physical entities (abiotic components). The scientific study of the interaction of biotic community with each other and with abiotic components is known as Ecology. Abiotic Components The abiotic components are also known as the abiotic factors. The

to their specific environment. Darwin concluded that the environment interacting with populations could cause evolutionary change. We now know that small changes in the ecological framework can cause changes long down the road. Environments always have both abiotic and biotic components. Abiotic are non-living components and biotic are things that are alive. All organisms in an environment are referred to as “biota”.

Ecosystem is the physical system (an open system) in which the mutual interaction between biotic and aboitic component motored by the energy component is studied. While the Ecology is the science which study the interrelation between Abiotic (inorganic) and Biotic (organic) components as well as the interaction among the biotic component. To make it more clear‚ ecosystem is the fundamental unit of ecological study. Ecology vs Ecosystem Ecology and ecosystem are two confusing concepts for those
