Molecules
A large molecule is known as a...
Macromolecule
Animals use specific behaviors for what ultimate goal?
(The goal of every living organism)
Survive and reproduce
What are the names of the trophic levels?
Producer
Primary consumer
Secondary consumer
Tertiary consumer
Describe the length of a carnivore's digestive tract
It is short because it's mainly digesting proteins
Organisms that share DNA are likely...

What element (think periodic table) is included in all organic molecules?
Carbon
Why is it beneficial to hunt in a group (ex: lions)
-To catch larger prey
-Get more energy while expending less
What do the arrows represent in a food chain/web?
Flow of energy
Describe the length of an herbivore's digestive tract
It is long because it has to digest tough plant material such as cellulose
Where does an organism get their DNA from? How much from each?
Mother and father, 50% from each (23 chromosomes from each)
Small repeating units that bond together to create macromolecules are known as...
Monomers
Why is it beneficial for prey to travel in herds?
Decreases an individual's chance of being preyed upon
What trophic level holds the most energy? (and therefore passes it to the rest of the ecosystem)
Producers
Why must organism's perform digestion?
To break down large molecules into usable forms for the body
Variations of a gene are known as...
Alleles
What do proteins get broken down into?
Amino acids
What is the benefit of reproducing offspring in large numbers at one time rather than small? (what do they have a better chance of doing?)
It is more likely that some will survive and reproduce
How much energy is passed from one trophic level to the next?
10%
In what digestive organ do most macromolecules (carbs, proteins, fats) get broken down in?
Small intestine
How can you tell if two organisms share a common ancestor?
Look at the genetic info and check for shared DNA/genes/alleles
What elements (think periodic table) does an organism need to build a protein?
C, H, O, N
Why is it important for species to communicate?
-To find food/resources for the group
-Take down prey as a group
-To escape predators/protection
What happens to the size of a population as trophic levels increase AND why?
Populations get smaller because there is less energy available
What happens to macromolecules after they're broken down?
They are absorbed into the blood stream and distributed via the circulatory system
Why is it beneficial for a mother to take care of a cub she is not the mother of, but still related to?
They still share genetic information so if that cub survives and reproduces her genes will still be passed on
