This is definitely a 5* tool to add to your MBB preps. Gives you the feeling of what the test might be, and how to solve these types of problems. Specifically good if you don´t have your degree from business school (like myself).
Would recommend 10 out of 10 :-)

Start building your food chain
Choose your core producers
Begin your ecosystem by selecting 3 producer species from the available 9. These foundational species generate the base calories your food chain needs.
Place your ecosystem in the environment that best fits your chosen species. Each location affects survival parameters like temperature, depth and elevation. Accuracy is crucial here.
Review your score, the food-chain eating order, and detailed explanations showing where your logic succeeded or failed. Each result helps you refine your reasoning and improve with every new attempt.
