  5. 12. If an ecosystem has two or more food sources for a predator, then the ecosystem might be able to be resilient if one of those food sources disappears. For example, if both elk and bison are available for wolves to eat, then the ecosystem may be able to be resilient if the bison are overhunted and die.  There may be enough elk for the wolves to still have food.

    13.Beavers are very important as keystone “engineers” in some ecosystems. Beaver dams can create water storage (ponds and wetlands). Beaver dams provide habitats for various organisms. The water storage and habitats can help to increase biodiversity. Beaver dams can even have the positive impact of lowering water temperatures downstream. If beavers are removed, wetlands and aquatic habitats can be damaged, and biodiversity can be decreased.

    14. If you grow your own produce and raise your own livestock (like chickens), you can reduce fuel use because those products aren’t being shipped and you don’t have to go to the store to get them. Backyard livestock can sometimes eat leftover food scraps (though not always), which reduces waste.

    7. Marine biologist Dr. James Estes researched sea otters and their habitats in the Aleutian Islands of the. Orthopedic Pacific Ocean. Sea otters feed on animals such as crabs and urchins . Islands with sea otters contained slot of kelp, a seaweed that is important food source for fish and other sea animals. However, islands without otters had large populations of urchins, this allows for kelp to freely grow in those areas.Given this information, what term best describes the otter in the Aleutian Islands ecosystem?

    A. Apex predator*

    A. It can signals the body to fight*
    B. It can signals the body to run
    C. It can inactivate pathogens in the body
    D. It can remove pathogens from the body

    11. Written the question is about beavers and how they benefit the ecosystem as keystone engineers describe a plausible impact thst the removal of the beaver could have on surrounding ecosystem.

    12.This question is about a birdwatcher sees a yellow small bird in a tree. Explain to the birdwatcher how he can use a dichotomous key to identify the bird. He knows nothing about the DK do write two ways of Dj that would help the birdwatcher.

    13. Rainbow trout live in the river and streams of upstate New York. Rivers in this area are cold and strong currents. If temps fall over time because of climate change,what is one variation that would help the trout survive? Why?

    Can someone please check my answers and see if they are correct??? The short answers I haven’t done yet but I don’t expect anyone to write those for me lol on those just some advice——but the ones checked yes please!!!!Please!!!

    10. nitrogen.
    11. composting scraps

    12. If all Bison disappear, all elk will too. Why this is because if there is more than one prey they won't be targeted as much as one prey. So two prey and more can have a good ecosystem, also if all bison disappear then the grass levels will increase because now there is only one herbivore.

    13. Beavers are considered the keystone engineers because they build dams to hold in water. Making more homes for other organisms that live in ponds and small lakes. It would be bad for the ecosystem if beavers disappeared because aquatic places like ponds, etc. would be damaged, and the biodiversity would most likely be damaged.

    14. It would be great to have livestock because you wouldn´t need to spend money on gas because you could eat eggs and drink milk. chickens and cows would be the most helpful because chickens eat just about everything, so that reduces food waste. chickens also lay eggs that are a good source of protein. cows on the other hand produce milk, that can be turned into ice cream, cheese, and other dairy products. That is why having livestock is a good idea.

    have an amazing day!

  31. I want to help some people!
    I do NOT want to encourage cheating, but to encourage learning! So, these will NOT be the answers you need to write, but an explanation of what to write! I saw some answers up top like this, but it didn't really help the way I needed it to.
    So, for Conexus 11-13 here are the answers!

    11. For eleven read the passage, find in the passage were the beaver helped is ecosystem. The part where they help their ecosystem is by making dams! The question asked to explain a potential benefit, and making dams is a benefit, but it can also harm the ecosystem. See, dams store water, provide renewable energy, and prevent floods, but unfortunately, they also cause a lot of harm (go read up on it I suggest searching how dams effect an ecosystem)

    12. For these questions explain what two steps of the dichotomous key that seems the most important. If you don't know what the dichotomous key is here are the steps (6 steps)
    Step 1: List down the characteristics.
    Step 2: Organize the characteristics in order.
    Step 3: Divide the specimens.
    Step 4: Divide the specimen even further.
    Step 5: Draw a dichotomous key diagram.
    Step 6: Test it out.
    I would say, draw a dichotomous key diagram, test it out, and divide the specimen are the three most important, but do as you please. Obviously, you can only pick two, that's why I am giving you as many as I think are correct so you can choose!

    13. Explain how the trout survives in the cold water. If this information helps you then you can use it: Trouts deposit aquatic material over their body to resist in extremely lower temperatures.

    I hope this helps in some way, because it did for me. As you can tell for all the questions I gave information, but also gave you a choice. I never said if the information will help you. This is because I don't encourage cheating. This way, you will most likely look up the information before submitting it. This is exactly what i want you to do. Sure, you used the information I gave you, but you also learnt that is was true along the way :) - A Helpful Student <3 (it makes my day to help fellow students, so please let me know below!)
