Correct Answer: A. al Qabah

Explanation

(a) Distance between Agbeyangi and Marafa as the crow flies

scale : 1:50,000

Distance on map between Agbeyangi and Marafa = 20.6cm

Actual distance = 50,000 x 20.6km 100,000

Therefore, the distance between Agbeyangi and Marafa is 10.3km

(b) The description of the drainage of the mapped area.

(i) River Oshin has many tributaries.

(ii) The mapped area is well drained as it is covered with numerous networks of well defined stream channels.

(iii) The river pattern is generally dendritic.

(iv) The rivers are at their early stages of development as evidenced by the dissected highlands caused by downward cutting.

(v) The central ridge is a major watershed from which many rivers take their sources.

(vi) The major river is River Oshin which flows in the North Eastern direction.

(vii) The river valleys are mostly V-shaped and the rivers in the Eastern part flow eastward.

viii) The smaller ridge at the North Eastern corner of the map has rivers radiating from it.

(ix) The rivers in the North-West flow northwards.

(c) Relationship between Relief and the Road Network

(1) The main road takes advantage of the lowlands and runs between the two major ridges in the map.

(2) The roads take advantage of the valley floors parallel to the IGPORIN hill thereby avoiding the highland.

(3) The secondary road, minor roads and main paths are constructed along spurs.

(4) Roads avoid steep slopes

(5) The roads are constructed through passes, col or sadles

(d) Land use types in the mapped area.

(1) Agricultural land use as shown by scattered cultivation.

(2) Educational land use due to the presence of schools.

Explanation

Nutrient cycling is the process where nutrients are passed through different organisms and the environment. The question is asking which group of organisms is critical in this process. The options are Aves (birds), Nematoda (roundworms), Mammalia (mammals), and Fungi. Out of the options, the correct answer is Fungi. Fungi are important in nutrient cycling because they are decomposers. They break down dead organic matter, such as leaves and wood, into simpler compounds that can be reused by other organisms. Fungi also form mutualistic relationships with plants, where they help the plants absorb nutrients from the soil in exchange for carbohydrates produced by the plants through photosynthesis. Aves, Nematoda, and Mammalia are not as critical in nutrient cycling as Fungi. While some birds and mammals may play a role in dispersing seeds and helping with pollination, they do not have as significant of a role in breaking down organic matter as fungi do. In summary, Fungi are critical in the process of nutrient cycling due to their ability to break down dead organic matter and form mutualistic relationships with plants.
