Key Words
Organic molecules contain what element?
CARBON
This trophic level includes organisms like grass, shrubs, and algae that produce their own food using photosynthesis.
What are primary producers?
Which macromolecule is the body's main source of quick energy?
Carbohydrates
Which level of the energy pyramid has the LOWEST biomass?
tertiary/quaternary consumers/top of pyramid
How many alleles do parents contribute to their offspring?
each parent contributes 1 allele
Why are keystone species important?
They have a specific role in the ecosystem AND/OR without them the ecosystem becomes unstable/collapses
These animals take up the third trophic level, eating primary consumers.
What are secondary consumers?
Which macromolecule is used to help build and repair muscle tissues?
Proteins
what is a niche?
a specific role in the ecosystem
What does inheritance refer to?
Passing on of genetics from parent to offspring
These organisms eat producers and are in the second level of the energy pyramid.
What are primary consumers?
As you move up the trophic pyramid, what happens to the biomass? Why?
It decreases -- less available energy
What is the monomer of a protein?
amino acid
which trophic level has the most biomass?
producers!
Bands in gel electrophoresis are sorted by...
size/weight/charge
amino acids and simple sugars are building blocks of what macromolecules?
proteins and carbohydrates
The second level of an energy pyramid, directly feeding on producers.
What are primary consumers?
What gives a molecule the potential for more energy when broken down?
More carbon/carbon bonds
Why is biodiversity important?
Ensures stability of the ecosystem
What group of macromolecules is a starch considered a part of?
Carbohydrates
How is energy transferred through an ecosystem?
Producers take energy in from the sun, which is then transferred through consumers (eating at each trophic level)
Which molecule contains the most carbon/carbon bonds?
Lipids/fats
We generate energy (ATP) by breaking down what type of molecules?
Macromolecules or ORGANIC (contains carbon) molecules
