1. what is the correct order of the steps in the scientific method?

a. write a hypothesis, test the hypothesis, analyze results, draw conclusions, and ask a question.

Explanation:

1. An ecosystem consists of biotic (living) and abiotic (non - living) factors. A population is a group of the same species, a community is multiple populations, an organism is a single living thing, and a biome is a large geographical area with similar climate and ecosystems.
2. A hypothesis is an educated guess or prediction. Elizabeth's statement about plant growth is a prediction (hypothesis), not a conclusion (which comes after testing), an experiment (the actual testing process), or an observation (just noting something without prediction).
3. The independent variable is the one that is changed on purpose in an experiment. The dependent variable changes in response, the control variable is kept the same, and "experimental variable" is not the standard term (independent variable is the correct term).
4. The scientific method is a series of steps (like making an observation, forming a hypothesis, testing it etc.) to solve problems. Observation is part of it, hypothesis is part of it, and "scientific steps" is too vague.
5. The correct order of the scientific method is: ask a question (first, to identify the problem), write a hypothesis (based on the question), test the hypothesis, analyze results, draw conclusions.

Answer:

1. E. Ecosystem
2. D. Hypothesis
3. B. Independent variable
4. A. Scientific method
5. (The correct order should be: ask a question, write a hypothesis, test the hypothesis, analyze results, draw conclusions. None of the options for 16 are correct as presented. But if we assume a typo and the intended order is similar to the scientific method steps)
