Which of the following are examples of symbiosis?
select all that apply.
__head lice complete an entire life cycle within a person’s hair and scalp; they cannot survive long away from a human host.
__deer range widely feeding on many different types of grasses, herbs, and woody plants.
__bees feed on flower nectar and pollen; in the process they move pollen from one flower to the next and plants mate.
__archaea (prokaryotes) live in the guts of ruminants like cattle; they cattle digest plant fibers and in return are provided with a warm place to live and abundant food.
__bark beetles live, feed, and breed within the soft wood just beneath the bark of their host trees.
__they leave the tree only for a brief time as adults.

The correct answers are:

__Head lice complete an entire life cycle within a person’s hair and scalp; they cannot survive long away from a human host.  

__Bees feed on flower nectar and pollen; in the process they move pollen from one flower to the next and help plants mate.  

__Archaea (prokaryotes) live in the guts of ruminants like cattle; they help cattle digest plant fibers and in return are provided with a warm place to live and abundant food.  

__Bark beetles live, feed, and breed within the soft wood just beneath the bark of their host trees.  

Explanation:

Symbiotic relationships are held by two different biological organisms that interact with one another. This collaboration can be beneficial to both (mutualism), beneficial to one and neutral to the other (commensalism), or beneficial to one and harmful to the other (parasitism).
