Correct Answer: B) It has no woody species

Explanation

This Biology question is asking which of the following statements about savanna is incorrect. The options are as follows: Option A: It occupies about 80% of the land surface of Nigeria. Option B (Correct): It has no woody species. Option C: It is usually burnt annually. Option D: It is a closed or nearly closed cover of grasses. Savanna is a type of ecosystem characterized by grassy plains with scattered trees or shrubs. Option B is the correct answer because it states that savanna has no woody species which is an incorrect statement. Savanna does have woody species, although they are not as densely packed as in a forest. Option A is true as savanna does occupy about 80% of the land surface of Nigeria. Option C is also true as savanna is usually burnt annually to maintain the ecosystem. Option D is also true as savanna is a type of grassland with scattered trees or shrubs. In summary, the correct answer to this question is Option B: It has no woody species. To learn more about savanna and other types of ecosystems, please see the relevant sections of the recommended textbooks.

Correct Answer: A. Shea butter

Correct Answer: B. 80°

Explanation

(a)Definition of soil erosion: This is the wearing away of soil by means of natural agents such as water, ice/ glacier, and wind.

(b) Factors that influence nutrient availability in the soil:

Soil pH, Concentration of other nutrients, Leaching, Crop removal/overgrazing, Oxidation and Reduction, Burning, Erosion, Soil moisture content, Level of organic matter/microorganisms in the soil

(c) Explanation of roles of factors of soil formation (i)Climate

- Abrassive action of rock particles blown by wind

- Rain may be severe enough to cause erosion

- Rain water causes chemical change of rock minerals' aids chemical weathering

- Temperature causes the expansion and contraction of rocks alternately leading to minerals with low expansitivity breaking away to form soil.

(ii) Living organisms

- Soil organisms like termites, earthworms eat deep into the soil and mix the mineral and organic matter together resulting in the formation of soil

- Activities of man during farming operation help to break rocks into tiny particles to form soil

- Roots of plants grow into openings in the rocks, physically forcing the rocks apart into smaller particles,

- Human activities can also cause erosion which result both in soil destruction and formation.

- Living organisms produce carbon dioxide which forms carbonic acid with water and enhances rock weathering,

(iii) Topography

-The shape of the land influences the movement and amount of water in the soil

- Hilly and slopy surfaces support erosion and encourage soil formation

- A flat and exposes the whole surface to equal environmental factors and therefor delays soil formation

- The topography of the land affects the distribution 0,i, plants and animals which influence the process of 01 formation

- More soil formation in the valleys than at the top of the hills

(d) Problems associated with overhead irrigation -

Wind distorts sprinkler patterns and causes uneven distribution of water

- The spray force can damage ripening soft fruits.

- A stable water supply is required for economic use of the equipment

- The water must be clean and free of sand, debris and large amounts of dissolved salts

- The initial investment is usually high

- Power requirements for pumping water is high

- Requires technical know-how

- Can spread diseases

- Lateral pipes hinder movement of farm machines

- High cost of maintenance/repairs/spare parts not readily available.
