SSCE VCE Biology Regulation of Plant and Animal Systems: A group of scientists investigat

Question

A group of scientists investigated two species of mammals living in their natural habitat. The scientists recorded the ways in which water was lost and gained by the mammals.
The findings are summarised in the table below.

| water gain         | mammal species A |           | mammal species B |           |
|--------------------|------------------|-----------|------------------|-----------|
|                    | mL/day           | % of total | mL/day          | % of total |
| drinking           | 0                | 0         | 1500            | 60        |
| eating             | 6                | 10        | 750             | 30        |
| metabolism         | 54               | 90        | 250             | 10        |
| water loss         |                  |           |                  |           |
| evaporation        | 43.9             | 73        | 900             | 36        |
| urine              | 13.5             | 22        | 100             | 4         |
| third avenue of water loss | 2.6         | 4         | 100             | 4         |

a. State two pieces of evidence from the table that suggest mammal species A is suited to survive in a hot, dry environment.
