Which of the following is an example of how living things, including humans, affect erosional and weathering processes?
a. animals burrow into soil and humans excavate souls when building.
b. decaying organic matter and burning off fossil fuels contributes to physical weathering.
c. plants contribute to erosion when. their roots exert pressure on rocks
d. all of the above.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

the correct answer in apex is tissue development, i know because i just had this question

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
