<span>Answer Beavers build Dams for food storage and protection. They build a dam tomake an artificial lake, and then they proceed to build their lodge nearby. Thedeeper water in a dam allows the beaver to travel near its home protected fromother animals and predators. After the dam is built, the beaver will also digchannels leading away from the new dam, to create safe transport channels forwhen it is gathering more wood to continue building its dam and lodge. Once itslodge and dam are built, the beaver will proceed to gather smaller pieces ofwood, and take it to the deep bit of the new lake directly next to the dam, andwill poke the wood into the mud. The cold water down there helps the wood staymuch fresher for longer. I have observed that beavers in the Rocky Mountainslove to eat the bark off of the Aspen trees. To get the bark, they must fell thetrees. As they use the trees closest to their beaver made lake, they get furtherand further away from the protection of the water of their dams. They then usethe logs or limbs (they have already eaten the bark) to make the dam higher andpush the water back to the edge of the aspen grove little by little. This is sothey can reach the water quickly when a predictor comes around.There is also astudy of dam building beavers being serinaded by the sound of running water (viarecording) in each case the beavers cover the speakers by the next day tosilence the noise. I don't think it because of the sound as much as it is to<span>prevent their predictors from using the sound to sneak up on them unnoticed.
hope it helps

Finding the volume of regular geometric objects uses standard formulas. The volume of a box equals length times width times height, for example. Not every object, however, fits a formula. Water displacement is best only used for irregular shaped objects.
<h2>Answer:</h2>
The correct answer is option C which is chemical waste.
<h3>Explanation:</h3>
- Wind is the renewable source of the energy. The air has energy in it which is used to run the generator to produce electrical energy from the mechanical energy of wind.
- Wind energy is perfect in sense of pollution. It does not create any chemical waste because there is no conversion or production of chemical energy involve in this energy production.
- While bats and birds death is caused by the fans used to run generators and a huge noise is also created by the wind energy production.
