Tropical rainforests are amazing places full of life. They have around 50% of all the plants and animals on Earth, even though they only take up about 6% of the land.

Here are some important reasons why rainforests are so rich in biodiversity:

1. Climate:

   • The temperature here is usually between 20 and 25 degrees Celsius.
   • It rains a lot too, with about 1750 to 2000 millimeters of rain each year. This makes the air and soil moist.

2. Layers of the Forest:

   • Rainforests have different layers, such as the canopy at the top, the understory beneath it, and the forest floor.
   • Each of these layers offers special homes for different kinds of animals and plants.
   • In fact, the canopy itself can be home to 50% of the species in the rainforest.

3. Nutrient Recycling:

   • Things like dead leaves and plants break down quickly in rainforests.
   • This helps create rich soil, which is really important for plants to grow.

4. Relationships Between Species:

   • In rainforests, many species rely on each other. For example, some animals help to pollinate flowers while others spread seeds.
   • These connections help the ecosystem stay balanced.

5. Isolated Areas:

   • Many tropical rainforests are cut off from each other.
   • This separation can lead to the development of new species because there isn’t much mixing between them.

All of these factors together make tropical rainforests some of the richest and most complex places for life on our planet.
