Hope This helped! 2022 answers, last 3 gotta do by yourself.

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.

WRONG I MISSED SOME OF THEM! HERE ARE THE RIGHT ONES!

1. grasshopper
2. birds
3. savanna
4. break down rock into soil
5. The coral is susceptible to starvation
6. coral reef
7. keystone species
8. They have another structure to obtain oxygen
9. more sweating
10. It can inactivate pathogens in the body

Trying to help is correct i got all of them correct, i will come back with essay answers one my teacher grades them

Vouch for "Trying to help", all the multi-choice ones he provided are correct.

1. grasshopper

2. birds
3. It breeds rapidly and has no predators in this environment.
4. They might introduce other organisms, like viruses and bacteria.
5. The coral is susceptible to starvation.
6. coral reef.
7. tourism
8. keystone species
9. The compost pile contained incorrect amounts of "greens" and "browns".
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!
DONT COPY the last 3 questions, put it in your own words!

thx @but u helped so many ppl! I hope u know just how many ppl are really grateful for you and your help!
