Sedimentary rock layers contain information about the relative ages of events and objects in Earth's history.

Cloning and stem cell harvesting. I just had a question like that in my biology class
Answer:
well from what i can see based on the data in the graph is that, since the accidental introduction of species 3 the population of the other 2 species has decreased quite a bit. While you can also observe that the population of population 3 continues to grow.
This suggests 3 possibilities to me
possibility 1. species 3 is consuming leaves just like the other 2 species causing a scarcity in food.
possibility 2. species 3 is consuming the other 2 species causing the decrease in population.
possibility 3. species 3 and the other species may be fighting over shelter, food, or water, causing more lizard fatalities.
