Certain species of birds are known to follow groups of army ants. As other insects leave their hiding places to flee the path of the ants, they are eaten by the bird. The relationship between the ant and the bird is what kind?
Commensalism.

This is the term for the number of organisms in a population that an ecosystem can support- growth will occur until this line is reached.
What is carrying capacity?

This biome is characterized by extremely harsh conditions due to year-round cold. It is found at the northernmost parts of Earth and while there are no trees, short grasses will grow during the brief summer.
What is a tundra?

Aphids secrete honeydew from their bodies, which is collected by ants and used as a food source. Ants protect aphids from predators by moving them underground to their colony. What kind of relationship is this?
Mutualism.

An ecologist notices that when the population of species A increases, the population of species B decreases. When the population of species B rises, the population of species A also rises. What kind of relationship can we theorize exists between these two species?
Predator-prey.
