Check the box next to the process or processes used by organism listed oak tree

Oak trees performs cellular respiration and photosynthesis so both boxes should be checked

Explanation:

"Plants" (seaweeds are not strictly plants) all can perform photosynthesis, in which they use chlorophyll to convert solar elergy into chemical energy (glucose). But they can also carry out respiration which is the opposite process. In respiration glucose is broken down and its stored energy is released and used as fuel for the organism's processes.

Conversely, animals such as the housefly, the rabbit and the crab in the lower part of the image, can only perform respiration.

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded
