Need help now Will make u extra points 1. What are three specific examples of organic matter?
2. What kind of organic matter could you find on a forest floor versus on a desert floor.
3. Is organic matter generally darker or lighter than soil when we are referring to color.
4. What do we use the soil texture triangle and what does it tell us, specifically?
5. Search for a picture of a "soil texture triangle." What do the numbers on the side of the triangle mean?
6. We know soil should be 25% air in composition, how does soil compaction affect the soil and what are some ways you can think of that we can bring air back into the soil?
7. There was a short introduction on soil profiles in this reading. After reading the introduction, what do you know about a soil profile?

answer in explanation.

Explanation:

1. plants, animals and bacteria

2.on a forest floor you could find: grass,bugs,leaves,mushrooms etc.

on a desert floor you could find...sand,microbes,feces and possibly animals.

3. It depends on the organic matter that is shown.

4. It tells you what the types of s o i l  are.

5. The smallest particles, which measure less than 0.002 millimeters, are called clay. ... Soils vary in their proportions of clay, silt, and sand. Soil scientists classify different soil types using the soil triangle. Each side of the soil triangle represents the amount of a particle of a certain size—clay, silt, or sand.

6. A possibility is we could pump air into the ground.

7. A product‐soil differs from the material from which it is derived in many ... Typically, horizons of a soil profile will follow the topography of a landscape. ... The area of the soil profile known as the “C Horizon” is comprised of parent material.

hoped this helped. :)

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

answer; both surfaces of the membrane are nonpermeable
