If you have a small fish pond with an aerator, turn it on during cloudy weather. Fewer daylight hours (during autumn and winter) also influence photosynthesis, as well as temperature and humidity.

Changes in the condition of a leaf (aging, tearing, etc.), the arrangement of leaves on a branch, even the shape and size of a leaf affects the amount of photosynthesis that occurs in a plant; so much so that two different types of plants have developed over time, based on their tolerance for light.

Different types of plants use different forms of chlorophyll for photosynthesis.

Chlorophyll a is the pigment directly responsible for transforming light energy (sunlight) into chemical energy (carbohydrates).

An abundance of suspended clay, silt, or phytoplankton (free-floating algae) can also make a lake turbid or murky, which may slow or prevent submersed plant photosynthesis and growth because of low-light conditions.

Fortunately for all animals, including humans and fish, oxygen is a by-product of this process.

As long as photosynthesis is occurring, oxygen is continuously being released into the air and into the world's lakes, oceans, rivers, and ponds.

Without sufficient soil-anchoring plants on the bottom, sediments continue to be re-suspended by wind and wave action, furthering the turbidity problem.

Several days of cloudy weather can slow the rate of photosynthesis, resulting in lower oxygen production within a waterbody.

The green hue we see in plants is the result of tiny grains of green pigment (light-absorbing molecules) inside the chloroplasts.
