Question
1)In the Arroyo Seco, the Western Toad feeds on beetles, bees, and small aquatic insects. The Bull Frog has been introduced and eats the same foods. The based on this information interaction between these two species can best be described as:
2)Introduced species such as the Polyphagous Shot Hole Borer can damage the communities they are introduced to by:
3)Species that compete for the same resources often switch to either use different resources or find ways to reduce competition. Why is this often true?
Parasite and HostExplanation / Answer
Ans1: competition
when two species have same needs for survival, then the two species compete for resources. In this case, the two frog species have the same need for food. Thus, their interaction can be called competition.
Ans2: (iv) spreading new parasites and diseases.
Polyphagous borer spreads a fungal disease, called Fusarium Dieback.
Ans3: (iii) direct competition harms both species, even the superior competitor.
This is true, when two competitors encounter, both are harmed, even when one wins. For eg, if a leopard and cheetah fight, either may win, but both will face severe injuries.
