A. Chipmunks and insects can occupy the same niche.

B. As the number of bears in this community increases, the number of chipmunks will increase.

C. Insects are classified as omnivores in alpine meadow communities.

D. Biomass decreases as energy is transferred from one level to another

The answer is D. Biomass decreases as energy is transferred from one level to another

The energy pyramid being referred to is in the attachment below.

Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.

<em>The rank in order from the most specific which is following .</em>

<em>(1) Reproductive isolating mechanism</em>

<em>(2) Sperm-egg incompatibility in sea urchins</em>

<em>(3) Gametic isolation </em>

<em>(4)Prezygotic isolating mechanism</em>

<em>(1) Reproductive isolating mechanism-</em> The components of regenerative confinement are an assortment of transformative instruments, practices and <em>physiological procedures basic for speciation.</em> They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile.

(<em>2) Sperm-egg contradiction in ocean urchins-</em> Bindin is a gamete acknowledgment protein known to control species-explicit <em>sperm-egg grip</em> and layer combination in ocean urchins.

<em> (3)Gametic isolation - Prezygotic hindrances </em>keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the<em> gametes (egg and sperm) </em>come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species  

<em> (4) Prezygotic isolating mechanism- </em>while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion.
