Changes in WHICH of the following factors will result in a change of an ecosystem's structure and composition?
- A: nutrient availability
- B: temperature
- C: number of trees
- D: light intensity
I got this question from an online "fun" quiz.
I understand that nutrient availability would affect the carrying capacity of an ecosystem. Temperature, if there was a big shift, could cause a change because some organisms would thrive and others would not. Light intensity affects the autotroph population.
But why would the number of trees not change it? I would think that if the number of trees changes, then the structure of the ecosystem would also have changed.
