Read the following extract carefully and answer the questions set.
Many organisms live on the sand dunes and in the valleys between the
dunes, forming a desert community. Ants, crickets, beetles, beetle
larvae and termites all feed off seeds and bits of organic matter which
the wind carries inland from the coast. The ants are eaten by ant-lion
larvae which hide in the sand. Spiders feed on the termites. Scorpions
eat beetle-larvae and spiders. Sun spiders, which are not true spiders,
devour the scorpions as well as the beetles and beetle larvae. Lizards
eat spiders, beetles and sun spiders. The side-winder adder feeds on
the lizards.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
