A biologist studying a desert ecosystem observes that the population of a lizard species increases following a particularly hot, dry period that causes a snake population to decline. What could the biologist hypothesize about the roles of these two species?
A.The lizard preys on the snake
B.The lizard is a parasite of the snake
C.The snake and lizard use the same limiting resource**
D.The snake is a keystone species in the ecosystem
I disagree.
Would it be d instead?
Yes, d.
