Answer: Income
Explanation:
In the ecosystem energy budget, primary productivity is like income. This is because primary production is the way in which energy enters an ecosystem.
I hope this helps :}
In the ecosystem energy budget, primary productivity is like income. Therefore, the correct option is B.
What is primary productivity?Primary productivity is the rate at which organic matter is produced by photosynthesis in an ecosystem. It represents the energy that enters the ecosystem from the sun and is available for consumption by other organisms. Therefore, like income, primary productivity is a source of energy that is available to be “spent” by organisms in the ecosystem.
Option A, debt, is not an appropriate analogy for primary productivity, as it implies a negative balance. Option C, the interest rate, is also not an appropriate analogy, as it does not represent a source of energy but rather a factor that affects the rate of exchange of energy. Option D, spending, is a closer analogy, but it does not capture the fact that primary productivity is a source of energy, rather than an action that depletes energy. Therefore, the correct option is B.

Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas (N2)
Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.
Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.
The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

escribe ONE way that the use of rodenticides affects the kit fox population AND explain how the size of the kit fox population is affected.
One way that the use of rodenticides affects the kit fox population will be a
reduction in the population.
Foxes are secondary or tertiary consumers which feeds on smaller animals
such as rodents in the ecosystem. The use of rodenticides will kill and
reduce the number of rodents available for food.
The reduction in the rodents means lesser source of food for the foxes and a
decrease in the population. The size of the kit fox population is affected
because a larger size being more affected than the ones with a smaller

What is necessary for the process of active transport to occur
Answer:
THE use of energy (usually in the form of ATP) is necessary for the process of active transport to occur.
Energy in form of ATP is necessary for the process of active transport to occur.
WHAT IS ACTIVE TRANSPORT:Active transport is the type of transport that involves the movement of molecules with the aid of energy (ATP). Active transport uses energy to move molecules against a concentration gradient unlike passive transport.Therefore, this means that energy in form of ATP is necessary for the process of active transport to occur.

A. The water is warmer than the land during the day.
B. Hurricanes that form in the oceans blow air into the shore.
C. During the day,solar radiation warms the land faster than the water.
D. Earth is tilted toward the Sun, causing air to move inland from the water
If I am correct, the answer is supposed to be C due to on hotter portions of the day, land warms much faster than the water. This causes cooler air to rise from the oceans and the wind currents then push the air towards the land.

When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.Explain with the help of genetics why all fish turn dark blue.
Answer:
The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;
This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)
What type of food was discovered to make up the majority of the diet of human foragers (and, by extension, likely our ancient ancestors)
Plant foods such as nuts, fruits and roots was discovered to make up the majority of the diet of human foragers. Hominine ancestors depended on foraging.
Hominine ancestors (i.e., before the evolution of H. sapiens), depended on foraging for millions of years.
Foraging refers to the search for wild food resources, which are provided by nature by gathering different sources (e.g., plants, small animals, birds, insects, etc).
Nuts, fruits and roots represent excellent sources of food because they contain both macronutrients (lipids, proteins and carbohydrates) and micronutrients (i.e., minerals and vitamins).

On average, men have a basal metabolic rate (BMR) of 1.0 kilocalorie per kilogram per hour. Lawrence weighs 198 pounds. Calculate how much energy Lawrence expends for basal metabolism per day.
The energy Lawrence expends for basal metabolism per day is 2,160 kilocalories per day.
Basal metabolic rate is defined as the amount of energy that is used when an individual is at rest.
This energy is used for life sustaining functions such as:
breathing,circulation,nutrient processing andcell production.To calculate the Basal Metabolic Rate for Mr Lawrence,
Lawrence weight = 198 pounds
60
(convert pounds to kilogramme)
1 pound = 0.453592kg
198 pounds = x
xkg = 0.453592 × 198
= 89.8 kg
But BMR for average men = 1 kilocalorie per kilogram per hour.
That is, 1 kilocalories = 1 kg per hour
x kilocalories = 89.8 per day
Therefore for a day = 89.8 × 24 ( 24 hours = 1 day)
= 2155.469184
approximately. = 2,160kilocalories per day

explain the correlation between solar radiation and kelp biomass.
Given what we know, we can confirm that although sunlight is beneficial to plant growth, intense solar radiation has been proven to be detrimental to the survival of kelp, thus reducing its biomass.
How does solar radiation affect kelp?Solar radiation is not harmful in very low amounts.
However, when exposed at long intervals or high intensity, it has been shown to cause tissue damage.
This tissue damage will inhibit the kelp's ability to undergo photosynthesis.
This means it will not be able to grow, and its biomass will be reduced.
Therefore, given the effect of solar radiation in damaging the kelp's ability to photosynthesize and thus reducing its growth, we can confirm that intense or prolonged exposure to solar radiation reduces kelp biomass.

Answer: The NEGATIVE CONTROL is the
test tube that is filled with ONLY distilled
water.
Explanation:
A negative control of an experiment is
carried out alongside the main primary
experiment except that the treatment is
changed to something that is predicted
to have no result. In the negative
control, the student does not expect any
response. This would help the student
compare the result of a new experiment
against an already known existing results.
Analysing the experiment carried out
by the student, She filled two test tubes
with distilled water and placed a piece
of Elodea in one of the tubes, leaving
the other without a plant. The other test
tube that contains only distilled water is
the negative control because she wasn't
expecting any result from it. It's also
served as a control sample to the primary
experiment. This is observed as she
blew in each tube to add carbon dioxide,
which caused the distilled water to
become more acidic. This would help the
student know that the that experimental
results are valid and to ensure that time is
saved

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.
Ernest would be swimming at 3.25 units on week 10
The explicit formula is given as:
[tex]a_n = a_1 + (n - 1) \times d[/tex]
Also, we have the following parameters
[tex]a_1 =1.0[/tex] -- the initial distance
[tex]d =0.25[/tex] --- the difference between concurrent distances
In week 10, the value of n is 10.
Next, substitute 10 for n in the explicit formula [tex]a_n = a_1 + (n - 1) \times d[/tex]
So, we have:
[tex]a_{10} = 1.0 + (10 - 1) \times 0.25[/tex]
Subtract 1 from 10
[tex]a_{10} = 1.0 + 9 \times 0.25[/tex]
Multiply 9 by 0.25
[tex]a_{10} = 1.0 + 2.25[/tex]
Add 1.0 and 2.25
[tex]a_{10} = 3.25[/tex]
Hence, Ernest would be swimming at 3.25 units on week 10
