Answer:
To eliminate alternative explanations for the results of an experiment.
Explanation:
The scientific experiments include all the procedure and observations that are observed during the experiments. The scientific experiments explain about the correct scientific information.
The particular hypothesis is tested by the scientific experiments. The experiments include controls and the variables. The variable that are used as hypothesis is not controlled and the results are matched directly. The other variables are controlled as this includes the other alternative explanation of the particular result.
Thus, the correct answer is option (C).
Flows of nutrients and energy
Flows of nutrients and energy link the producers, consumers, decomposers, and the abiotic environment in an ecosystem. Within an ecosystem, the producers obtain energy from the abiotic environment (sunlight). Consumers get nutrients and energy by feeding on other organisms. Decomposers get nutrients and energy by feeding on dead organisms or organic materials.
