c. parasitism
d. mutualism

1. a tapeworm living in the stomach of a human is a type of which symbiosis:

a. mutualism
b. commensalism
c. both a and b
d. parasitism

1. the pollinator - plant relationship is an example of mutualism because

b. predators
c. photosynthesizing plants
d. grazers

Explanation:

1. In lichen, both the fungus and the alga benefit from each other's presence. The alga provides food through photosynthesis and the fungus retains moisture. This is mutualism.
2. A tape - worm living in a human stomach benefits at the expense of the human, causing harm. This is parasitism.
3. In the pollinator - plant relationship, the pollinator gets food (nectar) and the plant benefits as its pollen is spread for reproduction. This is mutualism.
4. Herbivores eat producers (plants).
5. Scavengers, predators, and grazers are types of consumers. Photosynthesizing plants are producers.

Answer:

1. d. Mutualism
2. d. Parasitism
3. a. The pollinator gets food and the pollen is spread to other locations
4. a. Producers
5. a. Scavengers, b. Predators, d. Grazers
