Determine the relationships in which the listed organisms enter with each other: algae and mushrooms in a lichen
Determine the relationships in which the listed organisms enter with each other: algae and mushrooms in a lichen, a fox and a hare, a fox and a wolf, a liver fluke and a cow. What group of environmental factors are these relationships attributed to?
Algae and fungi in lichen are symbiotic. Symbiosis is a mutually beneficial existence of organisms, one helps the other and vice versa.
The fox and the hare are predation. Predation is a relationship between organisms, one eats the other.
The fox and the wolf are competition. Competition is a type of relationship where one organism has the same needs as another.
Liver fluke and cow – parasitism. Parasitism is a type of relationship between organisms where one (parasite) feeds on the other.
Environmental factors are: abiotic (factors of inanimate nature), biotic (factors of living nature) and anthropogenic (factors associated with human activities). The data are biotic.
