An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. [1] Abiotic factors include ambient temperature, amount of sunlight, air, soil, water and pH of the water soil in which an organism lives.
The environmental impact of agriculture involves a variety of factors from the soil, to water, the air, animal and soil diversity, plants, and the food itself. Some of the environmental issues that are related to agriculture are climate change , deforestation , genetic engineering, irrigation problems, pollutants, soil degradation , and waste .
An ecosystem (also called an environment) is a natural unit consisting of all plants, animals, and micro-organisms (biotic factors) in an area functioning together with all of the non-living physical factors of the environment. [34]
To explain these environmental factors, it is necessary to say that most of the factors depend on each other and that they change over the years. Consequently, when one factor changes it also affects the others. The equality for every company is the main characteristic of the factors in an environmental analysis. [6]
Limited cognition barriers are barriers that arise from a lack of knowledge and awareness about environmental issues. For example, with a key environmental issue like climate change, a person might not engage in pro-environmental behaviour because they are: unaware that climate change is occurring; or aware that climate change is an issue, but are ill-informed about the science of climate ...
These differences in abiotic components alter the species present by creating boundaries of what species can survive within the environment and influencing competition between two species. Abiotic factors such as salinity can give one species a competitive advantage over another, creating pressures that lead to speciation and alteration of a ...
Important abiotic factors affecting population growth include: Temperature – Higher temperatures speed up enzyme-catalyzed reactions and increase growth. Oxygen availability – affects the rate of energy production by respiration. Light availability – for photosynthesis. light may also control breeding cycles in animals and plants.
The environmental effects of climate change are broad and far-reaching, affecting oceans, ice, and weather. Changes may occur gradually or rapidly. Evidence for these effects comes from studying climate change in the past, from modelling, and from modern observations. [186]
