Summary Introduction

Introduction:

A forest is the most effective ecosystem. It supports any kind of organism or species. It absorbs the energy to build up organic materials. It occupies roughly 40% of the land. A forest usually has 200 millimeters of rain per year. The main reasons for the depletion of the forest are deforestation and the diversion of forest land for nonforest use.

In climatology, spring is the season of the year when temperature gradually rises between winter and summer. In the polar region, spring is very short.

A flower is sometimes termed as blossom or bloom. It is the reproductive organ present in flowering plants. Its role is to generate seeds through reproduction.

Germination occurs when seed or spore begins to grow. The seed produces a seedling that means spore is ready to develop during germination.

In climatology, autumn is the season after summer and before winter. In the U.S. this season is also called fall.
