In order to explain how change to physical components of a ecosystem effect population, you must use data from observation and investigations. These data are also known as a a statement B reasons c evidence d and argument
The data from observations and investigations in this context are referred to as evidence.
When discussing how changes to physical components of an ecosystem affect populations, evidence plays a crucial role in supporting the explanations. Evidence can include quantitative data, such as population counts or measurements of physical variables, as well as qualitative observations or experimental results.
For example, if studying the impact of deforestation on bird populations, evidence might include population surveys conducted before and after deforestation, which show a decline in bird numbers. Additionally, evidence could involve comparing the abundance of birds in deforested areas to nearby intact forests, providing further support for the negative effect of habitat loss on bird populations.
With evidence at hand, an argument can be constructed. An argument is a logical presentation or explanation of the evidence, demonstrating the cause-effect relationship between the change in physical components (deforestation) and its impact on the populations (decline in bird numbers). The argument puts forth a logical and well-supported interpretation of the evidence, leading to a conclusion.
In summary, in order to explain how changes to physical components of an ecosystem affect populations, it is essential to gather data from observation and investigations, which serve as evidence supporting an argument that connects the cause and effect relationship.
