Question

This table shows 3 different groups of crocodiles. Each group, A,B and C, is in a category based on their total lengths in meters. Study the chart and choose the statement below that is a valid conclusion based on the data in the table.

Question 1 options:

Group C does not have a preference between reptiles and bird.


The smaller the crocodile is, the larger the prey.


Overharvesting of fish will have a negative impact on Group B.

Answer 1

Since the main food source for the crocodiles from the group B is fish, overharvesting of fish will have a negative impact on Group B.

Overharvesting of fish or overfishing can usually have serious consequences on aquatic ecosystems, including organisms such as crocodile in this example. Overfishing results not only in affecting the balance of life in the oceans, but also of the coastal communities who depend on fish for their way of life.
