When these factors are changed or altered, the organisms should adapt to that change or else they will not survive. (b) What factors affect the distribution of plants and animals? Temperature changes can be natural, due to sunspots, weather-pattern shifts or ocean upwelling, or can be artificial, as with cooling-tower outfall, released water from dams or the concrete effect (concrete absorbing heat). Competition is when organisms compete for resources, such as food and territory. 5). Within an ecosystem, there are three different categories of organisms: producers, consumers and decomposers.
