Help me right know How are dolphins affected by the moon or seasons?

For dolphins that foraged at night, the presence of echolocation was reduced during nights of the full moon and during times of night that the moon was present in the night sky.

Explanation:

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.
