What is the general trend in the predtor-prey graph?
Predators and prey lag behind eachother, one increases and decreases AFTER the other. Never at the same time.

What do you call a trait/egenskaper that increases an organism’s chance of surviving, mating, and reproducing?
An adaptation

The passing of genes/traits from one generation to another
Heredity

List two main reasons why plants are essential to ecosystems (think about the products of photosynthesis).
1. Provide oxygen through photosynthesis for other organisms to use
2. Convert solar energy into glucose (chemical energy) for other organisms

What are the 4 aspects (parts) of evolution?
Heredity, Time, Variation, Natural Selection

How did the earth get oxygen?
From chloroplasts doing photosynthesis

Why do we draw arrows between organisms in a food chain?
Arrows represent the direction of energy flow (going from one organism to another).

List two organisms that would be directly affected if bees disappeared from an ecosystem, and one organism that would be indirectly affected.
DIRECT: -Plants/flowers (rely on the pollen)
DIRECT: -Birds (consume bees)
INDIRECT: Foxes, who eat the birds that rely on the bees

1 kilogram of beef contains 2356 calories, while 1 kilogram of macadamia nuts contains 7173 calories. Explain why this is.
Macadamia nuts come from plants which are producers. They contain much more energy since it comes directly from the sun. Beef comes from cows which are primary consumers, thus they only contain 10% of the original energy.

Describe what a limiting factor is and name 3 examples.
Anything that will slow down or stop population growth (ex: disease, lack of food and water, habitat destruction, natural disasters).

Fossil records (intermediate species), DNA Comparison, Comparative Anatomy, Embryos and Development

What were the four simple chemicals found in primitive (early) earth?
Water (H2O), Hydrogen Gas (H2), Ammonium (NH4), Methane (CH4)

Grass ---> Rabbit ---> Fox
In the above ecosystem, the rabbits have evolved to have darker skin and camoflauge better from the foxes. Explain how this will affect each other organism in the food chain in 6 months, and then in one year.
6 months:
Grass population will DECREASE due to more rabbits
Fox population will DECREASE due to less rabbits being visible.
Rabbit population will INCREASE due to better camoflauge.
1 year:
Overtime, the grass will run out and the rabbit population will likely crash. Fox population will also be low, and grass population will begin to increase again.

What are the four ecosystem services? Describe the name of each one and what they represent.
Cultural (human enjoyment/health), Provisioning (gives a physical resource to humans), Supporting (large, fundamental process), Regualting (one service that keeps the ecosystem processes going).
