1. Soil formation
2. Prevention of soil erosion
3. Recycling of waste
4. Pollination of crops
Select the correct answer using the codes given below.

Accepted Answer

Biodiversity supports human existence through various ecosystem services as highlighted in all four points.

1. Soil formation: Microorganisms like bacteria and fungi, along with earthworms, break down organic matter to create fertile soil.
2. Prevention of soil erosion: Plant roots bind the soil together, while vegetation cover reduces the impact of wind and rain, preventing the loss of topsoil.
3. Recycling of waste: Decomposers and detritivores break down organic waste and pollutants, returning essential nutrients back into the ecosystem.
4. Pollination of crops: Insects, birds, and bats are essential for the reproduction of many food crops, ensuring food security for humans.

Since all these processes are vital ecological functions provided by diverse biological organisms, option D is the correct answer.
