Meaning: "abiotic" means not alive, not from living things.

Wrong options:

• abotic: It leaves out the "i". Check the letters: "abiotic". A small spelling mistake loses the mark.
• biotic: This is the living type, not the non-living word needed here.

Correct answer: herbivorous

Explanation: Listen for "eaten by herbivorous animals". The sentence says plant eaters, so the word ends in ous.

Meaning: "herbivorous" means eats plants.

Wrong options:

• herbivourous: It adds an extra "u". Check the letters: "herbivorous". A small spelling mistake loses the mark.
• herbivore: "herbivore" is a close word, but it ends in "e". The speaker says "herbivorous", which ends in "ous".

Correct answer: carnivorous

Explanation: On the recording you hear "food for carnivorous animals". You need a describing word that ends in ous.

Meaning: "carnivorous" means eats meat or other animals.

Wrong options:

• carnivourous: It adds an extra "u". Check the letters: "carnivorous". A small spelling mistake loses the mark.
• carnivore: "carnivore" is a close word, but it ends in "e". The speaker says "carnivorous", which ends in "ous".

Correct answer: ultimate

Explanation: Listen again to "called the ultimate consumer". It follows "called the", so you need the word for the last one.

Meaning: "ultimate" means the last or final in a series.

Wrong options:

• ultamate: It has "a" where the word has "i". Write "ultimate". Only the exact spelling gets the mark.

Correct answer: energy

Explanation: Here you hear "transfer of energy takes place". You need a word for what moves between stages.

Meaning: "energy" means the power that moves through the food chain.

Wrong options:

• enegy: It leaves out the "r". Check the letters: "energy". A small spelling mistake loses the mark.

Correct answer: exhale

Explanation: The speaker says "animals and man exhale carbon dioxide". It comes before "carbon dioxide", so you need an action word meaning breathe out.

Meaning: "exhale" means breathe out.

Wrong options:

• exhal: It leaves out the "e". Check the letters: "exhale". A small spelling mistake loses the mark.
• exhaled: "exhaled" has an extra "d" at the end. The speaker says "exhale".
