Which causes the biodiversity of rainforests?
A. Primary disturbances

B. Stable ecosystems

C. Very little moisture

D.layclical disturbances

B. Stable ecosystems

Explanation:

The main cause of the biodiversity experienced in rain forests is largely due to the stable ecosystems that they enjoy.

A stable ecosystem is a sustainable one that does not change too much over the course of time.

Most organisms and the diverse life forms are easily nourished by the provisions made available by nature in such regions.

Most rain forest receives a large amount of solar radiation and energy all year round as the sun is directly overhead here. This suggests that the producers have enough energy to cater for their own need and that of the organisms there in. The consumers and decomposers have sufficient food available all year round. This coupled with other factors whereby organisms have specially adapted to environmental conditions makes a rain forest very biodiverse with life forms. An unstable ecosystem cannot be biodiverse
