Answer:
Temporal partitioning or niche differentiation
Step-by-step explanation:
Temporal partitioning refers to the variability in the competitive abilities of different species competing for the same resources based on varying conditions of the environment.
The environmental factors could be light, temperature, moisture, etc. Each species specializes in feeding within varied condition of one or more of the factors.
In this case, both species are in competition but while the first species feeds during the day, the second species feeds during the night. Here, light and temperature probably plays a huge factor.
Temporal partitioning is also known as niche differentiation, segregation, separation or niche partitioning.
