Question 5 unsaved in a tide pool, 15 species of invertebrates were reduced to 8 after one species was removed. the species remo
sesenic [268]
The species was a keystone species.

Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.

Species richness increases Select one: a. as we increase in altitude in equatorial mountains. b. as community size decreases. c.
olga55 [171]

Answer:

D) as we travel southward from the North Pole.

Explanation:

Species richness is the number of different species in a particular community. If we found 30 species in one community, and 300 species in another, the second community would have much higher species richness than the first.

Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change. Communities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species). Many other factors in addition to latitude can also affect a community's species-richness.

The process of photosynthesis can be represented by the chemical formula A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy B) C6H12O6 + 6H
miv72 [106K]
C.
6CO2 + 6H2O + Light -> C6H12O6 + 6O2

Light is needed as energy in order for photosynthesis to occur. Photosynthesis converts carbon dioxide and water into oxygen and glucose.
