1<br />The problem is asking us to identify the correct statement about a balanced ecosystem. A balanced ecosystem is one where the population of each species is in equilibrium with the other species and the environment. This means that the ecosystem is not static, but rather it changes in response to natural and human-caused events.<br /><br />## Step 2<br />Option A suggests that a balanced ecosystem doesn't change. This is incorrect because, as mentioned above, a balanced ecosystem is dynamic and changes in response to various factors.<br /><br />## Step 3<br />Option B suggests that a balanced ecosystem changes in response to natural and human-caused events. This is correct because a balanced ecosystem is indeed dynamic and changes in response to various factors, including natural and human-caused events.<br /><br />## Step 4<br />Option C suggests that a balanced ecosystem is always changing. This is also correct because a balanced ecosystem is dynamic and changes in response to various factors.<br /><br />## Step 5<br />Option D suggests that a balanced ecosystem is always changing in response to natural and human-caused events. This is also correct because a balanced ecosystem is dynamic and changes in response to various factors, including natural and human-caused events.
