Trophic levels organize organisms by the
a
amount of energy a source provides
feeding relationships
Oc
population of organisms
Od
producers in a food web
Answer:
Energy and the source applied
:
Trophic levels are a way of organizing organisms in an ecosystem based on their feeding relationships. The correct option is b.
The trophic levels represent the different levels of energy transfer and nutrient flow within a food chain or food web.
Organisms within an ecosystem are classified into different trophic levels based on their position in the food chain.
1. At the base of the trophic pyramid are the producers, also known as autotrophs. These are typically green plants, algae, and some bacteria that are capable of converting sunlight into chemical energy through photosynthesis.
2. The next trophic level consists of the primary consumers, also known as herbivores. These are organisms that directly feed on the producers. Examples of primary consumers include rabbits, deer, and grasshoppers.
3. The next level is occupied by secondary consumers, which are carnivores or omnivores that feed on the primary consumers. Examples of secondary consumers include snakes, birds, and frogs.
4. Tertiary consumers occupy the next level and are carnivores that feed on other carnivores. They are often at the top of the food chain. Examples include large predators like lions, sharks, and eagles.
Thus, the correct option is b.

The study of the form or structure of all living things
Answer:
The study of the form or structure of all living things is anatomy.
The study of form and structure of an living organisms is called anatomy.
Anatomy is a branch of science that deals with the form and structure of a living organisms. Anatomy includes external appearance as well as its internal parts. The study of anatomy started more than 2,000 years ago in the Ancient Greeks.
There are two main types of anatomy i.e. gross anatomy, and microscopic anatomy. The study of form and structure is known as anatomy so it is concluded that anatomy is the study of form and structure of an living organism.

When working with a microscope to focus on a specimen identify one safety issue to consider when switching to a higher power objective
Answer:
The correct answer is - One should always look on the side of the microscope so they don't break the slide and use fine adjustment knob only in order to avoid damage.
Explanation:
At the point when an example is in the center at high force, there might be 1-2 millimeters of room between the high power lens and the slide. On the off chance that you check from the side and see more space than that, you are not even close to having the example in the center.
In the event that you need a particular cell in the lower power field of view to be obvious in the high power field of view, it must be in the focal point of the low force field before you switch up to high power!
One should always look on the side of the microscope so they don't break the slide and use fine adjustment knob only in order to avoid damage.

The cheek smear slide is made by taking a q-tip or toothpick, rubbing it on the inside of your mouth (to remove cells) and then wiping or smearing it onto a blank slide. A stain is used on the cells so that you can see them, otherwise, they would be see-through. Look at the cheek smear slide using the 10x objective (total magnification of 100x). Approximately how many cells do you see inside the red circle
Answer:
The number of cells that will be viewed will depend on the size of the cells and the size of the red circle on the slide.
Explanation:
The cells have different sizes and this influences the number of cells that you will be able to view under a microscope.
The intensity with which the smear was made will also influence the number of cells viewed, as well as the quality and quantity of dye you used on the slide.
In summary, we can say that the number of cells that you will be able to visualize is relative and only the experience, in itself, will be able to determine a number.
The diagram below shows the skeletal forearms of different species. Although the functions are different what evidence of evolution is depicted?
Answer:
Due to the presence of different structure of forearms.
Explanation:
The evidence of evolution is depicted in the diagram due to the presence of different forearms of different organisms. The ancestor of all organisms are the same, but due to change in the environment changes occurs in the body structure of organism especially in the skeletal structure. This change in the structure requires millions of year to occur so that's why different organisms have different skeletal forearms.

A local recreation center has received funding to build a swimming pool. Prior to pool construction, engineers use computer models to compare which of several pool designs require the least amount of energy to be heated. What is the DEPENDENT variable in the computer models? a. pool size b. pool location c. pool shape d. pool temperature
Answer:
D. Pool temperature
Explanation:
The dependent variable in an experiment is the variable that is measured or responds to another variable called the independent variable. The outcome of the dependent variable is dependent on the independent variable.
In this computer model, the engineers compare which of several pool designs require the least amount of energy to be heated. The TEMPERATURE at which each pool design is heated is dependent on the type of pool design used. Hence, POOL TEMPERATURE is the dependent variable. It is the variable being measured in response to the type of pool design used.
