(a(i))[6]

Use the visible features of the organisms in the food web to fill the missing spaces in Table 2.1 and classify the named organisms.

(a(ii))[4]

Suggest and explain what could happen to the populations of snakes and beetles in the food web if the number of meerkats declined.

(a(iii))[2]

Suggest and explain why deserts generally have low biodiversity.

(b)[3]

Meerkats are social animals that live in groups of about $10$-$15$ individuals. When they are not above ground, they spend time in a network of burrows, which may reach a depth of $1.5\ \text{m}$. Suggest three ways in which these burrows help the meerkats to survive.
