Question

which of the following is an example of symbiosis?
two species of lizards that eat flies live in the same area.
plover birds eat the food caught in alligators’ teeth.
a mosquito bites a human.
a spider captures a fly in its web.

Explanation:

Symbiosis is a close and long - term biological interaction between two different biological organisms. Plover birds eating the food caught in alligators' teeth is a form of symbiosis (mutualism in this case as both the plover gets food and the alligator gets its teeth cleaned). The other options represent competition (two lizards eating flies), parasitism (mosquito biting human), and predation (spider capturing fly).

Answer:

Plover birds eat the food caught in alligators’ teeth.
