d

Question 2
A student is investigating the effect of light intensity on the rate of photosynthesis. She observes that as light intensity increases, the rate of photosynthesis increases. Which explanation best describes how the rate of photosynthesis can affect the biodiversity of an area?
a
A high rate of photosynthesis can decrease biodiversity because it allows more producer populations to survive which then deter consumer populations.
b
A low rate of photosynthesis can increase biodiversity because it allows more producer populations to survive which then attract consumer populations.
c
A low rate of photosynthesis can increase biodiversity because it allows more producer populations to survive which then deter consumer populations.
d
A high rate of photosynthesis can increase biodiversity because it allows more producer populations to survive which then attract consumer populations.
Question 3
A species that lives in every biome and is easy to track and count is best used as
MONARCH BUTTERFLY.Danus plexippus
a
a diverse species.
b
an invasive species.
c
an indicator species.
d
a keystone species.
