Primary successon

Answer 35

Bare rock, no soil, very slow, only lichens and moss can grow

Question 36

Secondary successon

Answer 36

After a disturbance and retains soil, faster (hurricane or fire)

What’s the math to find the net primary productivity

Answer 42

GPP subtract respiration

Question 43

Resource partitioning

Answer 43

Instead of fighting for the resource, species divide them
