Earth and its ecosystem are in a constant state of change. explain how a catastrophic environmental change, such as a wildfire in california, affects the local ecosystem. how does the ecosystem respond in this case

A wildfire in California can cause lots of changes in the ecosystem that has been affected by it. For starters the forests, shrubs and grasses will burn, so the basis of the ecosystem will be destroyed. While the grasses will grow again, the shrubs and trees will need much more time or might not even grow again at all. This leaves the animals without their environment to which they are adapted to, and instead of forest they will have a grassland (few months after). This usually causes big populations of animals to die out in that region. Also the soil will be exposed to erosion ones the trees are gone, which will contribute to quick changes in the shape of the terrain, and also the ground will be heavily affected by landslides after heavy rains. So all in all, the ecosystem will change overnight and it will have devastating effects on the flora, fauna, and the relief as well.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
