Match the 3 levels of the energy pyramid. (See pages 10-11) Carnivores- you know the
ones that eat meat.
1. Top Level
These producers are largely
the autotrophs (organisms
that manufacture their own
food by harnessing energy
from non-living sources of
energy.)
2. Middle Level
3. Bottom Level
Herbivores are animals that
depend only on the plants
for their nourishment and
survival.

my dad did alot of meth and ace cheeks

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

it's 3.2 on edge, i just took the test.

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
