ZOL2601
ASSIGNMENT 4 SEMESTER 1 2025

UNIQUE NO. 209620
DUE DATE: 13 May 2025

, Assessment 4

Question 1: CO₂ Production and Metabolic Rate

When animals breathe, they take in oxygen and give off carbon dioxide (CO₂). The
amount of CO₂ they produce can tell us how fast their bodies are using energy—this is
what we call their metabolic rate. Basically, the more active or "busy" an animal's body
is, the more CO₂ it gives off.

There are a couple of ways scientists can measure this:

1. Closed Respirometry: This is when the animal is placed in a sealed container.
As it breathes, the amount of oxygen goes down and CO₂ goes up. By
measuring these changes over time, we can figure out how much energy the
animal is using.
2. Open Flow Respirometry: In this method, fresh air is constantly flowing through
a chamber that the animal is in. We measure how much CO₂ is in the air before
and after it passes through the chamber. This gives us a real-time idea of the
animal’s metabolism.

So, by keeping track of the CO₂ an animal gives off, we can estimate how much energy
its body is burning, just like checking how fast fuel burns in a car engine.




Question 2: Glycogen Storage and Migrating Birds

Some animals store extra energy in the form of glycogen, which is a kind of sugar
stored in their liver and muscles. This stored energy can be used when the animal
needs it—like during exercise or when food is hard to find. Animals like humans, frogs,
and even some insects use glycogen as a short-term energy source.
