Question

A) Leaf-cutter ants cultivate fungus. The ants keep conditions optimal for fungus growth and carry leaf fragments for the fungus to grow
on. Then the ants feed on pieces of the fungus. Which kind of relationship exists between the fungus and the ants? (1 point)
predator/prey
consumer/producer
symbiotic
parasite/host

Question 3
Question 4
A) Which statement describes a consumer/producer relationship? (1 point)
One organism that benefits from living in or on another organism at the expense of that organism.

One organism eats another organism that makes its own food.
Both organisms benefit from each other.
A)
Owls and mice have a predator/prey relationship. Owls are the predators, and mice are the prey.
What happens to the mouse population when there is a decrease in the owl population?
(1 point)
It increases because there is more food available for mice.
It decreases because mice would not be eaten as owl food.
It decreases because there is less food available for mice.
It increases because fewer mice are eaten by owls.

Question 5
A) Fleas and dogs have a parasite/host relationship. What happens to the fleas in a home when another dog is brought into the home?
(1 point)
The flea population increases because the relationship is mutually beneficial.
The flea population decreases because the fleas harm the dogs they live on.
The flea population increases because there are more dogs to live on.
The flea population decreases because fleas are not be able to live on all dogs.

Answer 1

1) symbiotic — the ants and fungus have a mutualistic symbiosis (both benefit).

2) dogs and fleas — fleas are parasites and dogs are their hosts.

3) "One organism eats another organism that makes its own food." — describes a consumer (heterotroph) eating a producer (autotroph).

4) It increases because fewer mice are eaten by owls. — with fewer predators, mouse numbers rise.

5) The flea population increases because there are more dogs to live on.
