Answer:
A scientific investigation is a plan for asking questions and testing possible answers. A scientific investigation typically begins with observations. Observations often lead to questions. A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge.
Explanation:
The process of science involves asking a question and then forming testable hypotheses in order to gather evidence either to support or to refute it. So-called "cherry picking" of evidence to support an idea and ignoring evidence that may refute it does not advance knowledge and is not the scientific method.
Hoped this helped! :D
<h2>Answer:</h2>
The correct option is B which is plants.
<h3>Explanation:</h3>
Food chain contains:
- Producers: Organisms that produce food for their own and other animals. They convert simpler compounds into complex compounds.
- Consumers: They utilize the food made by the consumers. There primary, secondary and tertiary consumers.
- Decomposers: They convert complex organic compounds into simpler one.
So plants are autotrophic and they are the producers in food chain.
Hence Earth's food chain starts with plants.
Bacteria is prokaryote that live in almost every habitat.
I would go with hypothesis because I never heard any of the other answers in Bio and a hypothesis is an educated guess so it means what you already know and it’s an observation (I hope this helped!!)
