Hi, the given question from question 30 says that lost tropical rainforest according to soil composition, there are tremendous amount of diversity of fallies in tropical rainforests.
00:33
You might assume that rainforest soils are rich in nutrient.
00:36
In fact, rainforest soils are nutrient poor because nutrients are not stored in them.
00:59
No nutrient is stored.
01:09
So that heavy rains that occur in rainforest was organic material from the soil.
01:15
Although decomposition occurs rapidly in the hot, moist condition, many of the dead fallenly when other organic detritus were swept away before releasing all of their nutrients.
01:29
That's why the right answer from 30 is that most of the nutrient in the ecosystem are removed in the harvested timber that is option c is the right one now come to the point 31 pattern of succession related to succession so that as we know succession is a series of progressive change in the composition of an ecological community over time so that mainly two type of succession primary succession and secondary succession primary succession newly explored or newly formed rock is colonized by living things for the first time and in secondary succession an area previously occupied by living things is disturbed so that in the community an association of interacting population is usually defined by the nature of the interaction or the place in which they live.

It's called community can be used in the more limited sense such as plant community.
04:00
Animal community also also even the bird community...
