Dichotomous Keys and branching diagrams organize different types of information about classification. how are these tools used differently?

Answers

Answer:

In a dichotomous key you named then by their traits while in a branching diagram it already has the name and it's traits.

Explanation:

In dichotomous keys (also called single-entry or single-entry keys), a fixed sequence of alternatives must be followed, where multiple steps (including one or more characters) present two contrasting options (character states). As a result, only a single series of choices results in correct identification. Thus for each taxon there is a specific sequence of steps. An important factor of the dichotomous keys is that through them it is possible to name living beings through their characteristics.

A branch diagram can be used to represent a probability space. It can also be used to represent the various possibilities of a permutation or combination. This type of diagram provides a convenient way to organize information from a set of conditional events. In biology, the branch diagram shows the name and characteristics of a being and its relationship to different beings and characteristics.

To show the different levels of classification and divide among species, and different organisms on planet Earth. It also creates a universal "language" for scientists around the world when referring to organisms (cougar & puma are the same animals; different name)
Example: The American Alligator and the Chinese Alligator (look it up!) are in the same family and genus, but are not the same species.

Could a balanced ecosystem contain producers and consumers but not decomposers? Why or why not.

Answers

I believe the answer is "no" because decomposers are the ones who recycle everything. If they didn't break down dead organisms, there could be catastrophe.

How does the environment select organisms?

Answers

The process in which the environment selects organisms that will survive is called natural selection. It starts with overproduction; when an organism produces more offpsrings than can survive. The second is variation. Because there are so many offsprings, there will be variations. The third step is selection. When the actual "selection" occurs. If the variation is helpful to survive, then it gets passed down. This is the fourth step: adaptation when it is passed down to offsprings for generations.

The heat from the Sun must pass through the vacuum of space before it reaches the Earth. Which process is illustrated in this example?a.Induction
b.radiation
c.Conduction
d.convection

Answers

The question says, the heat of the sun must pass through the vacuum space before it reaches the earth. Which process is illustrated in this example. The correct option is B, that is, radiation. Radiation is the mode of transmission of heat energy as electromagnetic waves through space or through a material medium. Thus, the heat from the sun get to the earth surface through radiation.

the answer is b because radiation is the electromagnetic radiation from the surface of an object which is due to the object's temperature. It is also the only type of heat transfer that can move through the vacuum of space because electromagnetic waves to not need matter to travel.
