To determine which statement is true regarding the carbon balance in the ecosystem, we need to analyze the carbon input and output depicted in the graph. While I don't have access to the actual graph, I can help you interpret the statements based on general knowledge.
-
The ecosystem is balanced because equal amounts of carbon is entering and exiting the environment/atmosphere.
- This statement would be true if the graph shows that the amount of carbon entering the atmosphere is equal to the amount leaving it.
-
The ecosystem is balanced because non-equal amounts of carbon are entering and exiting the environment/atmosphere.
- This statement contradicts the concept of balance; non-equal amounts would indicate an imbalance.
-
The ecosystem is not balanced because more carbon is leaving the atmosphere than being absorbed by the atmosphere.
- This statement indicates that the ecosystem is losing carbon, which suggests an imbalance (more carbon exiting than entering).
-
The ecosystem is not balanced because more carbon is entering the atmosphere than being absorbed by the environment.
- This statement indicates an excess of carbon in the atmosphere, suggesting that the ecosystem is absorbing less than what is being added.
To choose the correct response, observe the graph closely: if it shows equal amounts of carbon in and out, select the first statement; if more carbon is entering, select the fourth; if more is leaving, select the third. The second statement is not valid in terms of balance.
Without the actual graph, I cannot definitively tell you which statement is true, but you should base your choice on the information presented in the graph.
