If there are 1,000 kilocalories of energy available at the
producer level, how much energy will be available at the 3rd
consumer level?

Answers

Answer 1

Answer:

1 kilocalorie of energy

Explanation:

As you go up from each layer, you divide the amount of energy by 10. (Otherwise known as the Rule of 10)

So if the producer has 1000 kilocalories of energy, the grasshopper would have 100 cause you divide it by 10.

Then from the grasshopper to the mouse, you would divide 100 by 10 to get 10.

And finally from the mouse to the owl, you divide 10 by 10 to get 1 kilocalorie of energy.

Answer 2

1 kcal, this is because it decreases by 10% after each level. so at the primary consumer level, it would be 100, secondary consumer = 10, and tertiary consumer = 1, and quaternary consumer = 0.1

Internal and External Structures

You are now going to construct an argument that plants have internal and external structures that support growth and reproduction.

Choose the internal and external structures you want to gather evidence and create a statement about.

subject: sciences

Answers

Explanation:

Some structures are internal, like the lungs, brain, or heart. Other structures are external, like skin, eyes, and claws. Some structures are unique, like the long neck of a giraffe. Other structures are more common, like a heartStructure and Function: Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction.

Plants have internal and external structures just like us humans do. While humans internally have lungs, a heart, and intestines Plants have that to. Plants have different fibers that allow the it to move water, make food, do photosynthesis, etc. So for this you could pick a couple different plant fibers such as the sclerenchyma fiber and the parenchyma fiber. The sclerenchyma fiber allows the plant to come out of the ground. This fiber is essentially its bones. The parenchyma fiber allows photosynthesis to occur. It moves water creates food etc.

I hope this helps! Good Luck!

A. John thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, John counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.

B. Candy notices that her shower is covered in a strange green slime. Her friend Belinda tells her that coconut juice will get rid of the green slime. Candy decides to check this out by spraying half of the shower with coconut juice. She sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.

Wave Rock, Australia
This concave rock formation is part of the northern side of Hyden Rock located in Hyden Wildlife Park, Western Australia. It is made of granite and estimated at 2.7 billion years old. The wave shape formed over the years by the action of running water weathering the middle faster than the top. The streaks on its face are minerals that were deposited by rainwater runoff.

What conclusion can be drawn about the number of elements the make up the majority of the world in which we live and the total number of elements identified on the Periodic table?

I think what you're reaching for is how the vast majority of the world we live in is comprised of only a few elements on the periodic table (carbon, hydrogen, oxygen, to name a few).

Explanation:

The other molecules identified on the periodic table do exist in nature but in much smaller quantities than those of a select few atoms.

Answer:

Of these 118 elements, 94 occur naturally on Earth. Six of these occur in extreme trace quantities: technetium, atomic number 43; promethium, number 61; astatine, number 85; francium, number 87; neptunium, number 93; and plutonium, number 94.

Create a nucleotide sequence with at least 9 DNA bases. Then, replicate your DNA strand using the appropriate DNA bases.

Answers

Answer and Explanation:

We need to create a nucleotide sequence, but first what are DNA nucleotides? They are the monomers of the entire nucleic acid strand of DNA.

DNA nucleotides have 4 bases: adenine (A), thymine (T), guanine (G), and cytosine (C). When pairing bases, A and T always go together and G and C always go together. (An interesting trick to remember this is Apple in the Tree and Car in the Garage.)

To create our own, we can draw up any combination of A's, T's, C's, and G's. I'm just going to arbitrarily write the following:

A A G C T T C G A T C G A C C

We need to pair these up by replicating it (remember A with T and G with C). The new strand will become:

T T C G A A G C T A G C T G G

Finally, we need to transcribe this back into the original format because replication is creating the same copy of something:

A A G C T T C G A T C G A C C

Answer:

plants or animals that migrated to new places where they are not native

Explanation:

Invasive species are non-native species that cause harm to the environment, economy, or human health. These species often outcompete native species for resources, prey on native species, and disrupt the natural balance of the ecosystem. They can also spread diseases to other species, and cause significant economic damage. Examples of invasive species include the emerald ash borer, zebra mussels, gypsy moths, and Asian long-horned beetle.

write a paragraph explaining the flow of energy through your food web. (100 points :>)

Answers

The flow of energy through the food web begins with the sun, which provides energy for the primary producers, such as plants, to undergo photosynthesis. The primary consumers, such as herbivores, eat the plants, and the energy is transferred to them. The secondary consumers, such as carnivores, eat the herbivores, and the energy is transferred to them. The tertiary consumers, such as apex predators, eat the carnivores, and the energy is transferred to them. Decomposers, such as bacteria and fungi, break down dead organisms and return nutrients to the soil, which can then be used by the primary producers. The energy flow through the food web is unidirectional, with energy being lost as heat at each level.

In a food web, the flow of energy starts with producers, such as plants or algae, which harness sunlight to convert it into chemical energy through photosynthesis. This energy is then transferred to primary consumers, also known as herbivores, which feed on the producers. As the energy moves up the trophic levels, it is passed on to secondary consumers, such as carnivores that feed on herbivores, and tertiary consumers that prey on other carnivores. At each transfer of energy, there is a decrease in the amount of energy available, known as the 10% rule, as some energy is lost as heat or used for metabolic processes. Decomposers, such as bacteria and fungi, play a crucial role in the food web by breaking down dead organisms and waste, releasing nutrients back into the environment to be used by the producers. This continuous flow of energy through the food web ensures that organisms obtain the necessary energy for their survival and maintains the balance and stability of ecosystems.

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
