In Activity A, you explored photosynthesis in a pond. The dissolved oxygen in a pond is produced by pond plants and algae (small, plant-like organisms) in a process called
photosynthesis.
What is the source of energy that is present during the time that photosynthesis takes
place?

Photons

Explanation:

Photons are the only source of energy for photosynthesis. Photons are absorbed by chlorophyll molecules within Photosystems I and II (and antennae complexes), generating higher-energy ‘excited’ states of the photosystems which can carry out energetically costly chemical reactions.

i am thinking the sun is the answer because the sun is usually the main source of energy that is included in photosynthesis

answer: populations of walruses and polar bears will decline

explanation:

you put it
