What is most likely to result immediately after a rainforest in brazil is clear-cut

It will result in less oxygen released into the atmosphere, erosion, animal extinction.

Through the process of photosynthesis, trees absorb carbon dioxide from the atmosphere and release oxygen into the atmosphere. If the number of trees decreases as the consequence of clear-cutting a rainforest, less oxygen released into the atmosphere and more co2 buildup.

Further, tree roots hold the earth in place, so with less trees, erosion could occur without the tree roots to hold the earth in place.

Nevertheless, trees represent habitat for many animals, therefore if the number of trees are cleared-out, loss of habitat of many animals will occur and diversity could decrease.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
