Why would houses ruin an animals habitat?
As animals like koalas possums birds and many others live in trees. And to make houses you need wood from trees, so when the tree gets cut down the animals home is gone and even sometimes the animal could still be in the tree and it can get killed when the tree falls to the ground.
Well, they did until humans dicided to ruin there habitat by burning and chopping down trees ( and killing, and skinning animals ) but somtimes people need to do these things for food, and survival, In other words: Animals WOULD accept there habitat if humans had not ruined it. Hope this help :) Jodie Cameron.
What is the role of the decomposer's in every food chain and web what will happen if they didn't exist?
Their main role is to recycle nutrients in dead organisms and their wastesIf all the decomposers were to die, there would be no organic nutrients and all the dead plants would ruin the animals' habitat; the ecosystem would be filled with plant and animal waste, and there would be no decomposition of waste material.
they can cause floods and damage to the sea shore and can damage/ruin the sea creatures habitat ADDED. They do no such thing. Coastal erosion and sediment transport is dependent partly on the tides and tidal currents; but these cannot be called "damage"; and the bit about harming the animals' habitat is absurd because the inter-tidal wildlife is adapted to that environment.
A developer plans to bulldoze a wetland to build a shopping mall how will this affect the water level in the area?
Fleas usually die when there is no blood to suck on, but if you really are convinced that fleas are living in your stuffed animals then I would consider give your stuffed animal a bath. Its simple really, just bathe it like you would an infant. Just don't use the washing machine or dryer otherwise it would ruin the toy.
