Algae live on the riverbeds of Bartlet National Park. These algae absorb light from the Sun and use it to make their own food. Moose in the park eat both algae and grass. The wolves in the park survive by hunting and eating moose.

Which of the following food webs best represents the relationships described above?

(Algae & Grass) ---> Mouse ---> Wolf

Explanation:

- Two arrows pointing towards mouse means it feeds on both algae and grass. Hence, mouse can be called an herbivore (feed on plants only)

- A single arrow pointing towards wolf means it feeds on mouse only. Hence, wolf can be called a carnivore (feed on animal flesh only)

Thus, the relationships is best represented as (Algae & Grass) ---> Mouse ---> Wolf
