Answer:

temporal summation

Explanation:

Temporal summation occurs when stimuli are applied to the same axon in rapid succession. These back to back stimuli cause overlapping EPSPs that sum. Temporal summation requires the buildup of neurotransmitter released by a single presynaptic end bulb two or more times in rapid succession that does not allow the postsynaptic neuron's membrane potential to return to the resting potential. The resultant postsynaptic potentials sum. A typical EPSP lasts about 15 msec. Therefore, temporal summation occurs when the second release of neurotransmitters occurs soon after the first one so that the postsynaptic neuron does not acquire resting potential.

Strangler figs are plants that attach themselves to trees for their growth and support. They absorb nutrition from the host tree
PIT_PIT [208]

Strangler figs are plants that attach themselves to trees for their growth and support. They absorb nutrition from the host tree and cause it to struggle to obtain sunlight and nutrients. This indicates that Strangler figs is a parasite to the trees.

Orchids are also plants that attach themselves to tropical trees. However, orchids don’t harm the host. Orchids obtain sunlight and moisture from their surroundings. This indicates that orchids are in a commensalist relationship with the trees.  

Both Strangler figs and orchids exhibit symbiotic relationship of two different kinds, namely, parasitism and commensalism.
