What Is Dichotomous Key

1.什么是二分法？

Adichotomous keyis an identification tool mainly used by scientists to classify and identify organisms into particular categories based on their traits. It helps classify animals, plants, bacteria, and any organism by matching their characteristics with known organisms. From thedichotomous key definition, we concur that it simplifies the identification of organisms by giving a series of statements with two answers that always lead to correct results. We can use a branching flowchart to illustrate the dichotomous key in biology.

科学家继续发现新的物种和生物，并将它们分为正确的类别至关重要。科学家使用特定方法来识别新发现的物种与已知物种之间的关系。它还回答了有关的问题二分键的目的是什么。It is a classification tool that helps scientists identify unknown organisms with multiple statements that best describe them. It is commonly used for plants or animals, but you implement it on any object. Here is an example of a dichotomous key.

2.二分法的类型

有四种常用类型的二分键。

1：分支

The branched dichotomous key uses a tree diagram to graphically represent statements with two choices, each leading to different answers. You can only use it to identify organisms one at a time because the tree can't move downwards from both sides.

2: Nested

这是二分法键的最简单易于理解的形式。您可以同时使用它来对两个生物进行分类。在嵌套的二分法中，每个语句的答案在导致它的答案之前筑巢。

3：计算机程序

一两个关键的计算机程序是一个most commonly used types because it makes everything easier for the user. It is quite similar to a quiz game. The user answers the question one at a time and proceed towards the correct identification.

4: Linked

链接的二分法键以列出的形式表示问题及其答案。您可以将其称为二分法关键工作表，在对对象进行分类之前，您获得的每个答案都会导致一个不同的问题。

3.什么是维ichotomous Key Used For?

Identifying Patterns:A dichotomous key is an identification tool used by people from a multitude of professions to identify patterns based on their opposing statements. After you test a sample using contrast multiple times, you will identify its boundaries and categorize it.

识别有机体：You can use a dichotomous key to identify organisms based on their characteristics. Thedichotomous keydefinition biology states that it can easily identify plant or animal species by comparing their behavior and other features with the know species.

对象的分类：The method of identification using adichotomous key可以轻松地应用于除生命形式（例如化学物质和石头）以外的物体。使用此类型的键，您可以同时对单个对象或一组对象进行分类。您可以使用它对不同对象进行分类。

4.如何使用二分键？

使用链接，分支和嵌套类型的dichotomous keyis simple because you make your diagram step-by-step and follow the learned procedure. With a computer program, you got to knowhow to use a dichotomous keybecause it gets complex sometimes to identify organisms or objects with limited information. Remeber these guidelines before you use the dichotomous key program.

• After you start the program, you will get a statement on the screen with two choices, and you will have to pick one.
• As you move on, the next statement will appear with two choices, while your previously selected choice will move to one side till you identify the object.
• After selecting the correct choice, the program will lead you to a single genus tree with a description and name of its species and some pictures to identify.
• 您必须继续选择具有正确特征的神秘树特征的选择，直到到达正确分类的树属为止。如果您发现错误的属，请重新开始过程。

5. How to Make a Dichotomous Key?

我们做二分键通过将其特征和行为与已知生物进行比较，识别和分类生物。如果您遵循适当的过程并牢记一些事情，则制作图表来说明您的二分法密钥很简单。确保每个声明仅导致两个选择。这是制作二分键的步骤。

• STEP 1:首先列出有关生物或对象的所有特征和特征的列表。
• STEP 2:List the characteristics logically by starting the list from its major features and moving towards its more minor features.
• STEP 3:在图中添加语句或问题，以将样品与其特征分开。始终将它们分为两组，以遵循二分法的正确布局。
• 步骤4：Add two choices for each statement of your dichotomous key. Lead both choices to the new statement and repeat the same step until you reach the last statement of identifying the organism.
• 步骤5：Make the dichotomous key diagram using a tree diagram or other illustrations that you think are suitable for your project. Please focus on the organism you are trying to classify and add all the statements and choices in the diagram before reviewing it and testing it out.

6. Dichotomous Key Examples

Here are some二分法的关键示例that will help you understand the correct format of adichotomous keydiagram used to classify plants, animals, and objects. You can also get the templates in these examples for free and use them to create your diagram onbob体育佣金。You can only make a perfect diagram by following the proper layout; that is why check out all of our examples before you make your diagram.

示例1：二分键工作表

The dichotomous key worksheet in this example illustrates the vertebrate classes of animals, insects, and fishes to help you identify the species using its statements. This diagram has four statements, each leading to two choices that move you to the next statement. These diagrams are mostly used in school books and daily lectures because students find them attractive and fun to read.

示例2：团队合作小册子

The purpose of the plant dichotomous key is to help you identify various species and types of plants based on their physical traits and characteristics that belong to other types of plants. The first statement in this example separates the specimen based on having vascular tissues. The next statements lead to two choices that move you to the next statement till you identify the plant species.

Example 3: Dichotomous Key for Animals

此示例中的图以图形方式表示动物根据其观察到的特征来帮助它们分类并将其列入类别的二分法钥匙。钥匙始于哺乳动物，移至鸟类和爬行动物，并以鱼类类别结束。这是一个较小成绩学生的学习图，因为它在阅读它的同时向他们介绍了二分法的钥匙。

7.关于二分键的常见问题解答

1. What is a dichotomous key example?

一个二分法的关键示例说明了如何使用其方法根据其特征来识别生物的方法。它最常用的示例之一是树的二分法钥匙。钥匙中的陈述会问您问题，例如树有叶子还是有针，它是宽阔的，还有其他相关问题。

2. What is a dichotomous key in simple terms?

In simple terms, adichotomous keyis a set of statements that gives you choices as you get in a quiz; you answer the statement by picking one of the choices and repeat the same step for the next statements till you reach a correct identification of any object. Scientists use it to classify organisms.

3.What are the three types of dichotomous keys?

The three common types of dichotomous keys are the nested, linked, and branched dichotomous keys. In the nested type, we get the answer of each statement nested right next to it. In the linked types, we use lists of text to identify objects. We use a tree diagram to make thedichotomous key在分支类型中。

8. Key Takeaways

Adichotomous key是科学家使用的鉴定工具，通过将其特征和行为与已知生物进行比较，将生物的特征和行为分类为类别。学生和化学家还使用此工具来识别岩石和化学物质等物体。bob体育佣金Edrawmax Online是最好的二分法主要制造商，它为您提供免费模板并支持各种文档格式。bob手机版网页体育它还带有一个综合的符号库。访问Edrabob体育佣金wmax在线，立即开始。您可以轻松地创建蜘蛛图bob体育佣金。它为您提供免费的专业模板和符号库来制作图表。bob手机版网页体育它还带有独特的自定义工具，并支持各种文档格式。寻找更多二分法的关键示例。
