Ecosystem, Week 3

Here's a quick summary: it rained in Africa, and the lions are slowly recovering.
The trees have grown back in Siberia, but the caribou have left Alaska, so the wolves will have to find other food sources.
The Ankylosaurs were hit by a sickness, but this isn't doing any damage to the ecosystem.
It rained again in the field.

Finally, a new species appeared in the tide pool: kelp, which brings with it another kind of snail called an abalone.
