A tapeworm and a cat have this type of relationship.

• mutualism
• parasitism
• commensalism
• competition

Type of symbiosis: Hummingbirds feed on nectar from flowers. The flowers are pollinated by hummingbirds as they move from flower to flower.

• commensalism

• mutualism

• parasitism

• predation

Type of symbiosis: Skunks often live in burrows that have been dug and abandoned by woodchucks.

• commensalism

• mutualism

• parasitism

• predation

Bird & Tree: A bird builds a nest in a hole in the trunk of the tree. It is protected from the rain and predators. The tree is not harmed or helped by the bird.

• Mutualism

• Commensalism

• Parasitism

• Competition

Bees use flower nectar for food, and they carry flower pollen to other flowers, allowing the flower to reproduce.

• Mutualism
• Commensalism
• Parasitism

Starfish are probably the most important predator in the shallow ecosystem because they eat basically anything that they can come across. Their feeding activities control the whole ecosystem. This is an example of the starfish ___.

• habitat
• biotic factors
• tolerance level
• niche

A relationship in which two species live closely together.

• resource
• mutualism
• succession
• symbiosis

What level of ecological organization would include all squirrels that live in the same area?

• biome

• community

• ecosystem

• population

All the different populations that live together in an area make up a(n)

• community.
• ecosystem.
• organism.
• species.

Several species of warblers can live in the same spruce tree ONLY because they

• have different habitats within the tree.
• don’t eat food from the tree.
• occupy different niches within the tree.
• can find different temperatures within the tree.
