Question

Answer 1

I'm not doing your homework for you . Get your book out read the chapter and you can discuss what ever you need to about d soil.

Answer 2

Burrowing invertebrates increase the aeration of the soil by making tunnels. They also increase soil nutrients by way of their excretement and decaying once they die. Plants also have a role in soil nutrients, the organic decaying matter once a plant dies and their role in the uptake of nutrients such as nitrogen. Plants play a major role in nutrient cycles. Plants also help with soil structure, they are key players in stabilising unstable ground, their roots hold the soil together.

Hope that was of some help

If I had an answer for you I would give you one but I don't.  Sorry.

Answer 4

what is bontan

Answer 5

Worms help aerate the soil and help water get down to the roots of plants by digging tunnels and loosening the soil. Their waste is a fertilizer and also affects soil pH. Insects like ants and some small animals like moles and gophers do this as well. Fungal hyphae also loosen and organify soil as well as convert dead plant and animal matter to organic nutrients. Some bacteria affix to roots and rhizomes of plants and fix atmospheric nitrogen, converting it into organic forms that plants can use to build proteins.
