Explanation

(a) After Philip had completed his work in Samaria, the angel of the Lord directed him towards Gaza. There, he met an Ethiopian Eunuch returning home after worshipping in Jerusalem. The spirit of God directed Philip to join the Eunuch in his chariot and Philip heard the Eunuch reading from Isaiah. He asked him whether he understood the passage but the Eunuch answered that he could not, except somebody put him through. He, therefore, invited Philip into his chariot. The passage was about the sheep being led to the slaughter. He asked Philip whom the prophet was referring to: himself or to somebody else. Philip started from this passage and developed it to preach the good news of Jesus to him. When they came to a body of water, the Eunuch asked him what could prevent his baptism. They went down into the water and Philip baptized him. Thereafter, the spirit of the Lord caught up Philip and the Eunuch saw him no more. He went on his way rejoicing.

(b) Philip's preaching of the Gospel message to the Ethiopian Eunuch is significant in many ways:

(i) He took the Gospel beyond Jerusalem and Judea, through Samaria and into Gentile territory and beyond.

(ii) The Holy Spirit received on the Day of Pentecost was active in the Church; Philip's activities bore eloquent testimony to this.

(iii) The Ethiopian Eunuch, as the first African' convert to Christianity, probably initiated further evangelization into Africa.

(iv) It shows the need for divine inspiration in understanding and interpreting the scripture.

(v) Preachers and ministers of God should help in interpreting the word.

(vi) All christians are obliged to evangelize.

Silas Marner

Comment on the friendship between Silas Marner and William Dane.

Silas Marner has a gentle, loving nature and a truthful, simple soul. On the other hand, William Dane is a hypocritical, self-righteous young man. The two first meet at Lantern Yard during the betrothal of Sarah to Silas Marner. They both belong to the same church prayer meeting group and Silas Marner feels at home in the company of William Dane.

Silas Marner is highly thought of in the community,, being a young man of exemplary life and ardent faith. At one of the prayer meetings, Silas Marner is struck by a cataleptic fit which jeopardizes his chances of marrying Sarah, even though there is not enough reason to break an engagement which the church approves of. William Dane then seizes the opportunity of Silas' fit to set him up as they take their turns in watching over the ailing senior deacon at night. As fate would have it, Silas Marner had previously used his knife to cut William's strap for him forgetting to replace it in his pocket.

On that fateful night senior deacon dies, Silas Marner must have had his fit again, for suddenly, he realizes that the Deacon has been long, dead and wonders why William has not come to take his turn watching over the deacon. Apparently, William placed Silas' knife near the deacon's bed and went away with the bag of money while Silas is unconscious, sneaks into Silas' chamber and tucks the empty bag behind the chest of drawers to frame Silas.

This act leads to the summoning of Silas to the church where the lots cast declare him guilty. His hope in God to vindicate him proves futile and when he hears that William has married Sarah, he becomes totally disillusioned and devastated. This state of mind drives him to a new "land" Raveloe where he becomes a different person altogether. He lives a solitary life and, with his faith in God shattered, he keeps aloof from his neighbours altogether who in turn ostracize him.

Thus, as a result of William's betrayal, Silas' life in Raveloe is described as — "an eager life filled with immediate purpose which fenced him in from the wide, cheerless unknown". However, it is a barren life devoid of human relationships except with his gold. The only being that makes an inroad into his affection is the child, Eppie, who reminds him of his own little sister. From the moment he finds her, she becomes a "light" in his life and his "window" to the outside world.

(a) (i) Ecosystem:

Is a natural unit consisting/made up of living/biotic/organism and non-living/abiotic elements/factors; interacting to produce a stable system.

(ii) Abiotic environment:

The non-living components of the ecosystem; such as light/pH/water/oxygen/wind/temperature etc.

(b) Ecological factors that are specific to:

(i) Aquatic habitat

Salinity; turbidity; tidal movement; dissolved gases; density; substratum; water current.

(ii) Terrestrial habitat

Humidity; soil; topography; wind; altitude; availability of water.

(c) The relationship between grass and rabbit in a given habitat

• Grass (green plants) can photosynthesize/ manufacture its food;
• Rabbit which cannot manufacture its food feeds on grass;
• During respiratory process, rabbit gives out carbon dioxide as a waste product;
• Grass makes use of the carbon dioxide to manufacture its food;
• Grass during photosynthesis gives out oxygen as a by-product which the rabbit uses for respiration;

When a rabbit defecates/ dies, bacteria/fungi cause its decay, which forms manure that is absorbed as soil nutrients by grass.

(d) Pyramid of energy

Correct Answer: D) Fourth

Explanation

In Biology, a food web is a diagram that shows the transfer of energy from one organism to another in an ecosystem. The organisms in a food web are grouped into different trophic levels based on their feeding relationship. The trophic level of an organism refers to its position in the food chain or web. Primary producers are at the first trophic level, primary consumers at the second, secondary consumers at the third, and tertiary consumers at the fourth trophic level. The question is asking which trophic level tertiary consumers belong to in a food web. Tertiary consumers are organisms that feed on secondary consumers, which in turn feed on primary consumers that consume primary producers. Therefore, tertiary consumers are at the fourth trophic level in a food web. The correct answer to this question is option D: Fourth. Tertiary consumers belong to the fourth trophic level in a food web. It is essential to understand the concept of trophic levels and how they relate to the feeding relationships in a food web. To learn more about this, please read the relevant sections of the recommended textbooks.
