1. Using the grid provided, label the x-axis “Year". Label the x-axis with the years listed in picture one below.
2. Based on the sizes of the numbers for each population, create a scale on the two separate y-axes (similar to the snowshoe hare-lynx graph). Place the moose population on the y-axis on the left side of the x-axis and the wolf population on the y-axis on the right side of the x-axis.
3. Construct a line graph using the data from Table 2. Use a different coloured line for each population.
4.Give your graph a title. Create a legend for your graph so it is easy to read.
after your done with graph please answer this questions!
1. Describe the relationship between the moose and wolf populations.
2. What biotic and abiotic factors might influence the moose and wolf populations?
3.How would the carrying capacity for wolves be influenced if a large number of moose were killed by humans?

Answers
Answer:
Here is the graph
Explanation:

Answer:
the moose and wolf population is increasing on 1960 and 1965.moose population is increasing but wolf population decreases on 1970.both are increasing on 1975 and 1980.moose population decrease but wolf population increases on 1985.wolf population decrease but moose population increases on 1990 and 1995.moose population decrease but wolf population increases on 2000 and on 2005.Explanation:
2.yes, biotic and abiotic factors might influence the moose and wolf populations.if there is more population of wolf ,moose population will be less
3. the carrying capacity for wolves be influenced if a large number of moose were killed by humans is that the number of wolf automatically decrease when a large number of moose were killed.as wolf is totally depend on moose.

In this case, we have a large population of lizards that live on an island. These particular lizards can either have an all-green tail or a tail with a black tip. In the large population there are many of each type, but one day, two green-tailed lizards and three lizards with black-tipped tails were picked up by a sailor and dropped off on an island that had no lizards of this kind. It was noted that the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators. The lizards began to breed and eventually produced their own large population after a few years. Make a prediction about what you might find if you visited this island after several years based on what you have learned.
PLEASE HELP!!!
Answers
This is a complicated question that's a little easier if you break it down!
Island One:
- Lizard tails are all green or black tipped.
- This island has many of each type.
Sailors Moved:
- two green-tailed lizards
- three black-tipped lizards
On Island Two, we know that the black-tipped lizards are more likely to survive since the question tells us that "the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators".
The green tailed lizards do not have this advantage, and the predators are eating more of them because of this (especially if there are a lot of predators!).
We also know that the lizards on the island were able to reproduce and form a large popuation- not all of them were eaten by predators.
Based on this information we can predict:
There are going to be a lot more black tipped lizards (or they may all be black tipped lizards) because they have an advantage in surviving longer.

Moving a book to a lower shelf decreases potential energy.
True
False
Answers
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

Sewage sludge (biosolids) removed from a municipal wastewater treatment plant is a mixture of organic material and water. Research and explain why the incineration of sewage sludge may require more energy than it produces. Explain why people may be reluctant to use biosolids as a fertilizer for food crops.
Answers
Hey love! <3
Answer:
Sewage systems are used all around the world transferring waste to treatment plants where they are filtered and traded in for organic material. If the sluge were to be incinerated it could be repurposed, however the gas used to burn the sewage waste comes from condensing saturated fuel oil and requires 195 SCM of natural gas to successfully complete the chemical transfer. That's a lot of energy, and the natural process costs plenty more then what you're getting in returns. Through the process toxins can develop inside of the incinerated waste which could poison crops and animals, studies also show the process can release carbon monoxide into the air. To conclude it's called sewage waste for a reason, what goes down should stay down instead of putting what we eat and inhale at stake.
Hope this helps out! (ﾟヮﾟ) Sincerely, Kelsey from Brainly.

The incineration of sewage sludge may require more energy than it produces because of the high cost of energy.
Municipal wastewater treatment plants are estimated to consume more terawatt hours per year of electricity, which equates to about billions in annual electric costs. That's a lot of energy, and the results show that wastewater sludge able to produced up to 44.82 ml biogas/kg of sludgePeople may be reluctant to use bio solids as a fertilizer for food crops.

Nucleotide-for-nucleotide was discovered to differ from the human genome with which it was compared by roughly 1.23 percent. This equates to roughly 40 million changes in our DNA, with half most likely the result of mutations in the human ancestral line and the other half occurring in the chimpanzee line since the two species split.

Why is it important for there to be different species in an ecosystem? What would happen if all the species were the same? Explain why biodiversity matters.
Answers
Answer: Biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines. If all animals in an ecosystem were of the same species, the balance would be lost.
Explanation:
An ecosystem is a set of living beings (of different species) that share the same habitat or biotope. There are first of all primary producers, those that are capable of producing organic matter from inorganic compounds. These organisms are autotrophs, such as plants. Then we find in the second step the consumers, heterotrophic organisms (herbivores, carnivores or omnivores) that feed on matter and energy produced by other living beings. And in the last link of the trophic chain of organisms that make up an ecosystem we find the decomposers, those that feed on dead organic matter. In this way, there are complex interactions between different organisms of different species.
Thus, biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines.
If all animals in an ecosystem were of the same species, the balance described above would be lost. If they were all producers like plants, there would be no consumers to control the plant population. If they were all consumers, they would eventually run out of food. And if they were all decomposers, they would not have enough dead organic matter to feed on either. A greater number of species or biological diversity in an ecosystem makes it more resilient. Because species can absorb and reduce the effects of environmental changes on the overall structure of the ecosystem. In addition, they can reduce the chances of a change to a different state.
