Why is the world's loss of biodiversity a source of concern? O a. Humans depend upon other organisms for food and oxygen
b. Species have value to humans, both monetary and because we like them
c. Tourism depends on the preservation of certain animal species
d. Both (a) and (b)

Species have value to humans, both monetary and because we like them.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
