Undertstanding P values

Hi everyone

I wonder if anyone might be able to help me?

I'm trying to interpret the P value of this graph, however I'm not very knowledgeable about statistics.
Ad libitum.png

Would I be correct to say that the P value at 0.001 shows very small significance of the results and that we can therefore reject the null hypothesis?
What would I say the null hypothesis is? Is it that there is no significance between age and ad libitum energy intake?

I'm very grateful for any help.
Thank you :smile:
