Suppose that you have just started a summer internship working for a cooperative service, where you will collect soil samples, conduct laboratory and field tests, and make recommendations on soil conservation and agricultural practices.

(i) Identify one biome that is characterized by soil that is rich in humus. Describe how humus originated in the soil of this biome and TWO ways that humus improves conditions for plant growth.

(ii) Describe TWO soil conservation practices that are designed to decrease soil erosion. *

seen below

Explanation:

I) Deciduous forest: is an example of a biome (a biome is a large naturally occurring community of flora and fauna occupying a major habitat) it's seasonal/tropical and temperate.

Humus which is an organic component of soil originated here because of plant and animal materials decomposition on the forest. Two ways humus improves soil conditions includes;

a) by providing fertility or nutrients for plants and soil organisms.

b) humus also helps the topsoil hold water.

II) Two soil conservation practices that decreases erosion include;

a) Conservation tillage, minimizes the number of tillage passes, where the soil aggregate disruption is reduced, and a minimum of 30% of the soil surface covered with residues, and this aims to reduce by disturbing the soil as little as possible when planting crops.

b) Terracing or division terrace, this helps by shaping the land to create level shelves of earth to decrease soil and water runoff, thereby decreasing erosion.

1: the largest region of the brain is the:

  cerebrum

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis
