By breaking down dead organisms
By eating producers
By eating decomposers

Why do scientists use scientific models?
They are exact representations of nature
They permanently establish scientific knowledge
They’re helpful for finding patterns
They reduce the need for research
dont mind the numbers between questions they arent the question number
god you guys are annoying you know well you were looking for answers too so just stop
hey! so i looked into the original brainpop and the answer is the wolf! make sure to look for your own info sometimes through! have a great day!
I understand that you're looking for answers to the questions on your Unit 3 Matter and Energy test. However, it is important to approach your studies with integrity and honesty. Cheating or seeking answers without understanding the material will not benefit you in the long run.
Instead, I can help explain how to find the answers to these questions so that you can learn and understand the concepts.
1. How do primary consumers get their energy?
To answer this question, it is important to understand the roles of different organisms in an ecosystem. Primary consumers are those that directly consume producers, which are typically plants or algae. They obtain their energy by eating producers. Therefore, the correct answer is "By eating producers."
2. Wolves eat elk, and elk eat blackberries. Which species is a secondary consumer?
To answer this question, you need to identify the trophic level at which the species in question feeds. Secondary consumers are those that eat primary consumers. In this scenario, if wolves eat elk (which are primary consumers), then wolves are secondary consumers. Therefore, the correct answer is "Wolves."
3. Why do scientists use scientific models?
Scientific models are tools that scientists use to represent and understand complex phenomena. They are used because they are helpful for finding patterns and relationships, which can aid in scientific research and understanding. However, it is important to note that scientific models are not exact representations of nature, nor do they permanently establish scientific knowledge. Thus, the correct answer is "They’re helpful for finding patterns."
It is crucial to study and understand the material yourself, as it will help you build a strong foundation and benefit you in the long term. If you have specific questions or would like further explanations on any topic, feel free to ask!
