HELP!!! The graph on the left shows the total supply and consumption of forests
zzz [600]

Answer:

A

Explanation:

The number of different species in a particular habitat is what is what makes up the biodiversity in such habitat. The more varied the species are, the higher the biodiversity.

There are factors that could lead to a decline in the biodiversity level of an habitat which is illustrated by the two graphs above. One of such factors is over exploration of a forest.

The graph shows that as consumption of lumber increases at a faster rate compared to how forest is replenished, the amount of lumber available for supply also reduces. As this goes on, biodiversity keeps declining.

In summary, we can say that:

"When forests are cut down faster than they can be replenished, biodiversity quickly decreases."
