Question

1. analyze which ecological interactions are present in the community described below? select all correct answers.

pitcher plants are carnivorous plants that grow in bogs, which are wet areas that have little water flow. winged insects become trapped in the plants long tube - like structures where they die and get absorbed by the plant. bogs also provide habitat for frogs that feed on winged insects, snails, and slugs and grass snakes that feed on frogs, fish, and small mammals.
a. pitcher plants are predators.
b. frogs compete with pitcher plants.
c. grass snakes and frogs are competitors.
d. grass snakes have a symbiotic relationship with winged insects.
e. winged insects have a symbiotic relationship with pitcher plants.

Explanation:

• Option A: Pitcher plants trap and absorb insects (their prey), so they are predators.
• Option B: Frogs and pitcher plants both consume winged insects. Competition occurs when two or more organisms vie for the same limited resource (in this case, winged insects).
• Option C: Grass snakes eat frogs. This is a predator - prey relationship, not competition.
• Option D: Symbiotic relationships involve a close and long - term interaction between different species. Grass snakes eat winged insects (if they can catch them, but the main food of grass snakes in the given context is frogs, fish, and small mammals). There is no symbiotic relationship here.
• Option E: Pitcher plants trap and kill winged insects (a predator - prey or consumer - resource relationship), not a symbiotic relationship (which would imply some mutual benefit or at least a non - harmful close interaction).

Answer:

A. Pitcher plants are predators.
B. Frogs compete with pitcher plants.
